Proof Holdings MCP server

• add_challengerFree

  Pre-enroll a Proof-Me challenger (a trusted contact) on a HITL config. Enabling the first challenger opts the config into Proof-Me. A telegram challenger captures its chat_id later at enrollment; a whatsapp challenger must pre-declare its phone. Agent usage: After adding a challenger, call invite_challenger to mint the single-use enrollment link the challenger taps to bind their messenger identity. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• add_circle_memberFree

  Add a pending member to a Circle by name, with an optional pre-declared WhatsApp phone. The Telegram chat id is captured later when the member taps the enrollment deep link. Agent usage: after adding a member, call invite_circle_member to mint the single-use enrollment link the member taps to bind their messenger identity. ACCESS: needs a Proof account.

• create_accountwrite actionFree

  Create an account-bootstrap session for agent-driven onboarding. Public endpoint (no API key required). Returns a session id, channel-specific instructions, and — FOR TELEGRAM AND WHATSAPP ONLY — deep_link, qr_code (base64 PNG) and qr_text (UTF-8 text QR). The endpoint is safe to call regardless of whether the submitted identity is new: completing verification transparently creates a User when none exists, or logs the user in when one already does. The response is intentionally uniform — the server does NOT reveal whether the identity is already registered (this would be a user-enumeration oracle). If the agent needs to distinguish new-vs-returning users, call `get_current_user` after verification and inspect the user's `created_at`. EMAIL CHANNEL SENDS NOTHING HERE. The response carries email_sent=false and send_required=true: confirm with the user that the address is theirs, then call send_account_email. The other channels dispatch nothing either way — the user sends the first message themselves (reverse OTP). Agent usage: (1) Call create_account with the user's chosen channel. (2) For email, confirm with the user and call send_account_email. On telegram/whatsapp pass `deep_link` to render_auth_link, which prints the clickable link and a QR code beneath it. On sms `deep_link` is an EMPTY STRING and render_auth_link will reject it — show `sms_message`, which is what the user sends; this response carries no destination number, so do not invent one. Do not hand `qr_text` to a link renderer either — it is the link already rendered as QR art; print it verbatim inside a fenced code block if a real terminal needs the QR. (3) Call wait_for_account_creation with the session id until verification completes. (4) On verified, JWT + refresh cookies are set; proceed with whatever follow-up the agent was asked to do.

• create_api_keywrite actionFree

  Create a new API key. The secret key value is returned ONLY in this response — store it securely. Note: the secret will be visible in the AI conversation context. Optionally bind the key to a sub-account (project) via profile_id — outbound messages sent with the key are then branded as that project. Agent usage: This operation requires 2FA. Before calling, complete the 2FA flow: (1) call start_2fa with action_type "api_key_create" and the user's preferred channel, (2) tell the user a code was sent and wait for them to verify, (3) poll get_2fa_status until status is "verified", (4) then call create_api_key — the backend session will be elevated. If you get a 403, the 2FA session has expired — restart the flow. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• create_authorizationwrite actionFree

  Create a new authorization request. Authorizations grant permission to send confirmations to a user via a specific channel. The user must approve the authorization before confirmations can be sent. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_chat_id_discoverywrite actionFree

  Create a Telegram chat ID discovery token. Returns a deep_link, qr_code (base64 PNG), and qr_text (UTF-8 text QR for terminal display). The user opens the link in Telegram, which reveals their chat ID for HITL config setup. Agent usage: pass the response's `deep_link` to render_auth_link so the user can click or scan it. Never hand `qr_text` to a link renderer — it is that same link already rendered as QR art. Print it verbatim inside a fenced code block only when a real terminal needs the QR. Then poll poll_chat_id_discovery with the returned token until the chat_id appears. Use the discovered chat_id when creating a HITL config with a Telegram channel. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_circlewrite actionFree

  Create a Circle — a named group of trusted contacts (the people-primitive powering Proof-Me and Approvals-on-Circle). Optionally seed initial members; each member's declared channels are stored so they can be invited to enroll. Agent usage: after creating a Circle, add members with add_circle_member (or seed them here), then invite_circle_member to mint the enrollment deep link each contact taps to bind their messenger identity. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_circle_member_drillwrite actionFree

  Fire an on-demand Proof-Me drill against one enrolled member — a real cross-channel identity challenge carrying the scheduled-safety-check label (the account owner practices confirming). Complements the automated daily drill + monthly reinforcement sweeps. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_confirmationwrite actionFree

  Create a HITL confirmation request. Sends an approval request to the channels configured on the referenced HITL config. First response wins. Agent usage: The HITL config referenced by hitl_id must be authorized before you can create confirmations. If this returns a 403 or "not authorized" error, call request_hitl_authorization on the HITL config first, then wait for the user to approve via the messaging channel. After creating a confirmation, poll get_confirmation to check for approval/denial, or use get_confirmation_approval_link to generate a fresh link for the user. Encryption (v1 vs v2): when the HITL config has E2E encryption enabled, `message` must be a JSON ciphertext envelope, not plaintext. Choose the version by who must be able to decrypt: - v1 (single-recipient): wraps the content key for the config owner only. Use when there are no enrolled non-owner approvers. - v2 (multi-recipient): additionally wraps the content key for each enrolled approver via an `approver_ek` map, so every approver can decrypt. Use when the config has enrolled approvers — otherwise approvers get "wrong password" on the approval page. Build it with the SDK `encryptMessageV2(plaintext, ownerPublicKey, hitlId, approverKeys)` after fetching the approvers via the SDK `getApproverKeys(hitlId)` (`GET /api/v1/hitl/:id/approver-keys`). AAD is the `hitlId`. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_delegationwrite actionFree

  Create a delegation (Proof of Delegation): a control-proven domain authorizes a typed url/purl artifact for a set of capability scopes and receives a publishable signed token. The attestation is that the domain's controller authorized this artifact — nothing more; it says nothing about the artifact or the business behind it. Each mint is a billable proof. A requested lifetime longer than the control proof's remainder is rejected, never truncated. The result carries the publishable token AND the DERIVED effective_status/is_valid — the same pair the list and get tools return, so the shape does not depend on which verb produced it. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_dns_credentialwrite actionFree

  Store DNS provider credentials for automated domain verification. Note: credentials will be visible in the AI conversation context. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• create_hitlwrite actionFree

  Create a HITL (Human-in-the-Loop) config. Defines which messaging channels receive approval requests and the default timeout. Agent usage: After creating a HITL config, you must call request_hitl_authorization before it can be used with create_confirmation. For Telegram channels, use create_chat_id_discovery first to discover the user's chat ID, then include it in the channel config. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_identity_challengewrite actionFree

  Create a Proof-Me cross-channel identity challenge (CONFIRM) for an enrolled challenger. The account holder approves/denies on a channel different from the one the suspicious contact reached the challenger on. Agent usage: poll get_identity_challenge with the returned ID until it reaches a terminal state (active = confirmed, denied, expired). ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_multi_channel_verificationwrite actionFree

  Create a multi-channel phone verification: one phone number challenged over several channels at once (OR / first-wins). The first channel the user completes wins, yields a single proof token, and cancels the losing siblings. Exactly one proof is billed, at the winning channel's completion — not one per channel, and nothing at creation. Agent usage: the response includes a `group_id` (format vg_<hex>) and a `channels` array — each block carries a `deep_link` (WhatsApp/Telegram) or an `sms_message` to present to the user — pass the `deep_link` to render_auth_link. A block's `qr_text` is that same link already rendered as QR art, not an alternative address: print it verbatim inside a fenced code block or leave it out. Poll get_multi_channel_verification_status with the group_id to track completion and retrieve the proof token when a channel verifies. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_profilewrite actionFree

  Create a new profile with optional display name, bio, avatar, business info, and theme settings. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_sessionwrite actionFree

  Create a new phone verification session. Returns deep_link, qr_code (base64 PNG), and qr_text (UTF-8 text QR for terminal display). Sessions provide a hosted verification flow with callbacks. Agent usage: After creating a session, pass the response's `deep_link` to render_auth_link so the user can open or scan it. Never hand `qr_text` to a link renderer — it is that link already rendered as QR art. Print it verbatim inside a fenced code block only when a real terminal needs the QR. Then use wait_for_session to poll until the session reaches a terminal state (verified, failed, or expired). ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_user_requestwrite actionFree

• create_verificationwrite actionFree

  Create a new identity verification. Initiates a verification flow for an asset identifier (phone number, email, domain, social handle, wallet address, account, or Telegram bot). Agent usage: pass the asset `type`, the delivery `channel`, and the `identifier` (e.g. type "phone", channel "sms", identifier "+37060000000"; or type "email", channel "email", identifier "user@example.com"). The response carries a `challenge` object with the instruction for the chosen channel — except a `telegram_bot` verification made with a LIVE key, which the server completes on the spot and answers with `status: verified` plus a proof token and no challenge at all; with a `pk_test_` key that same call stays pending and does carry a challenge. On the messenger channels it also carries `challenge.deep_link` — pass THAT to render_auth_link to give the user a clickable link and a QR code. This endpoint returns no `qr_text` at all. For OTP-based flows (sms/email), the user receives a code — poll get_verification or use wait_for_verification to track completion. For Telegram/WhatsApp, the user clicks the deep link to verify. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• create_verification_requestwrite actionFree

• list_delegationsFree

  List your own delegations with optional filters. Each item carries the DERIVED effective_status/is_valid beside its stored status — read effective_status, since status records only whether the owner revoked the delegation themselves, so a delegation still reads active there after its domain control proof was revoked, suspended or expired, and after its OWN lifetime ran out. effective_status accounts for all of those: it reports expired once either lifetime has passed, whichever is earlier. Tokens are not included in the list — use get_delegation for the stored token. There is no public enumeration of third-party delegations. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• regenerate_api_keyFree

  Regenerate an API key, issuing a new secret while keeping the same ID and settings. The old key stops working immediately. The new secret is returned ONLY in this response. Note: the secret will be visible in the AI conversation context. Agent usage: This operation requires 2FA. Before calling, complete the 2FA flow: (1) call start_2fa with action_type "api_key_regenerate", (2) wait for user to verify the code, (3) poll get_2fa_status until "verified", (4) then call regenerate_api_key. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• remove_challengerwrite actionFree

  Remove a Proof-Me challenger from a HITL config. Removing the last challenger disables Proof-Me on the config. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• remove_circle_memberwrite actionFree

  Remove a member from a Circle. Deletes the member's channels and revokes any live authorizations that routed through them. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• remove_circle_member_channelwrite actionFree

  Remove a channel from a Circle member. Removing the last channel is allowed (the member simply becomes unreachable). ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• remove_emailwrite actionFree

• render_auth_linkFree

  Render an authorization or verification URL as a clickable link followed by a scannable QR code inside a fenced code block. This is a local computation tool — no HTTP request is made. Agent usage: pass a LINK field from an earlier response — `deep_link` (create_session, create_chat_id_discovery always; start_login, create_account, start_2fa, start_2fa_for_action on telegram/whatsapp ONLY, where on sms and email that field is empty or absent altogether and this tool rejects it either way), `challenge.deep_link` (create_verification, messenger channels only), or `telegram_deep_link` / `whatsapp_deep_link`. Do NOT pass `qr_text` to this tool: that field is a QR code already rendered as text, and this tool takes a link. When a response gives you `qr_text` and no link, print it verbatim inside a fenced code block instead — its rows only scan while they stay adjacent, so a blank line or wrapped row destroys the code.

• render_templateFree

  Render a template with provided variables. Returns the fully rendered message content. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• request_hitl_authorizationFree

  Request authorization for a HITL config. Sends consent requests to all configured channels (Telegram/WhatsApp). Users must approve before confirmations can be sent. Agent usage: This must be completed before create_confirmation will work for this HITL config. The consent request is DELIVERED to each channel — the response carries no link to show. It returns `authorizations` — one entry per resolved recipient, each with its `channel`, `recipient`, `authorization_id` and `status` — plus a `message`. Read the entries rather than assuming: `status: 'pending'` means consent was just sent and the user must approve in Telegram/WhatsApp itself, while `status: 'active'` means that recipient had already authorized and nothing was sent to them. An EMPTY array does not mean everyone is authorized — it means no recipient could be resolved at all (usually a HITL config bound to a missing or inactive circle, or channels whose recipient is blank), so nobody was asked and waiting for an approval would hang forever. Do not relay `message` on that branch: it reads 'All channels already have active or pending authorizations', which is exactly the wrong conclusion. Read the array. After requesting, you can proceed once the user confirms they have approved. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• resend_domain_emailwrite actionFree

  Resend the domain verification email. Rate limited to 3 requests per minute. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• resend_email_otpwrite actionFree

  Resend the OTP code for an in-progress email addition. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• resend_verificationFree

  Resend a verification message (email channel only). Generates and sends a new code. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• retry_webhook_deliveryFree

  Retry a failed webhook delivery. Creates a new delivery attempt with the same payload to the configured endpoint. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• revoke_api_keyFree

  Revoke an API key by ID. The key will immediately stop working. This action cannot be undone. Agent usage: This operation requires 2FA. Before calling, complete the 2FA flow: (1) call start_2fa with action_type "api_key_revoke", (2) wait for user to verify the code, (3) poll get_2fa_status until "verified", (4) then call revoke_api_key. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• revoke_assetFree

  Revoke a verified asset by ID. The asset will be marked as revoked and associated proofs will no longer validate. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• revoke_auth_sessionFree

  Revoke a specific authentication session by ID. When called via JWT, cannot revoke the current session. When called via API key, any session can be revoked. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• revoke_authorizationFree

  Revoke an active or pending authorization. Only authorizations with status "active" or "pending" can be revoked. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• revoke_delegationFree

  Revoke ONE delegation. The domain control proof and sibling delegations stay valid; the revocation is mirrored into the proof registry so the CRL, status list and public status lookup all see it. Idempotent: a repeat revoke answers success with the same body, both here and through revoke_proof with the ph_dlg_ handle — unlike a PROOF, where a repeat answers already_revoked. The result carries the DERIVED effective_status/is_valid beside the stored status. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• revoke_proofFree

  Revoke a proof by its public handle (ph_ctl_* / ph_dlg_*) or a verification ID — the same addresses get_proof_status takes. The proof token will no longer validate anywhere: the status endpoint, the public validator, the revocation list and the Token Status List all report it revoked. This action is irreversible. It revokes the PROOF only — the asset, consent or delegation the proof is about is not withdrawn. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• searchFree

  Prefix-anchored global account search across six resource buckets (verification_requests, verifications, hitl, confirmations, authorizations, api_keys). Case-sensitive prefix match over indexed plaintext fields only; recipient identifiers are masked. Results are scoped to the authenticated account. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• send_account_emailwrite actionFree

  Deliver the verification email for an account-bootstrap session created with channel "email". Public endpoint (no API key required). Why this is a separate call: create_account deliberately sends NOTHING. A message from proof.holdings arriving in someone's inbox is an act with a person on the other end, so it takes an explicit second step rather than being a side effect of creating a session. ASK THE USER to confirm the address is theirs before calling this — do not call it automatically after create_account. The other channels (telegram, whatsapp, sms) never need this: the user sends the first message themselves (reverse OTP), so nothing is dispatched to them at all. One session sends at most one email, including under concurrent calls. A repeat answers 410 already_sent, which means the material backing the send is gone: usually because the email went out, occasionally because an attempt was interrupted mid-send and nothing was delivered. Do not tell the user a message was sent on the strength of a 410 — create a new session instead. (A session the recipient cancelled via the decline link, or an expired one, answers 404, not 410.) If delivery fails the response carries email_sent=false and the call can be retried.

• set_primary_emailwrite actionFree

  Set an email address as the primary email for the account. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• set_primary_phoneFree

  Set a phone number as the primary phone for the account. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• set_primary_profileFree

  Set a profile as the primary profile. The previous primary profile becomes secondary. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• setup_domain_emailwrite actionFree

  Set up email sending for a verified domain. Configures the domain for sending verification emails from a custom address. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• share_request_emailwrite actionFree

  Send an email notification to the subject of a verification request. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• start_2faFree

  Start a two-factor authentication challenge for a sensitive operation. Sends a verification code via the chosen channel. Returns a session ID, and for messaging channels: deep_link, qr_code (base64 PNG), and qr_text (UTF-8 text QR for terminal display). Agent usage — full 2FA flow: (1) Call start_2fa with the appropriate action_type and channel. (2) Present the challenge, and do NOT announce a message the server did not send: email is the ONLY channel it dispatches on. On telegram/whatsapp the user opens `deep_link` and sends the message themselves; on sms they send `sms_message` to a number from `sms_dids`; the response's own `instructions` field says which. On email, a 200 carrying `requires_email_selection: true` and `available_emails` means nothing was sent and no session exists — ask which address and call again with `email_id`. For telegram/whatsapp, pass `deep_link` to render_auth_link; for sms, show `sms_message`. Never hand `qr_text` to a link renderer — it is the link already rendered as QR art, so print it verbatim inside a fenced code block only when a real terminal needs the QR. (3) Poll get_2fa_status with the returned session_id until status is "verified" (the user enters the code on their device) or "expired". (4) If verified, proceed with the protected operation (e.g. create_api_key). If expired, inform the user and offer to restart. Typical channels: "telegram" or "email". For email, the user may receive a magic link instead of a code — the backend handles this automatically. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• start_2fa_for_actionFree

  Start a 2FA challenge that grants the authenticated user permission to perform a sensitive action. The 2FA must complete on a channel DIFFERENT from the user's last login channel (the backend enforces this). On success a grant is stored keyed by the user id and action_type; middleware on the protected endpoint reads the grant and allows the mutation. Destructive action types (api_key_create, api_key_revoke, api_key_regenerate, api_key_view, account_delete, phone_remove, email_remove, revocation_bulk) are capped at 5min TTL and forced single-use by server policy. Configuration scopes (settings_write, profile_update, templates_write) allow up to 24h TTL and caller-chosen single_use — useful for agents making multiple settings mutations in one session. Agent usage: (1) Attempt the sensitive call; if you get `403 2fa_required` note the `action_type`. (2) Call start_2fa_for_action with that action_type and a channel different from the login channel. (3) Present the challenge: on telegram/whatsapp pass `deep_link` to render_auth_link; on sms show `sms_message` and the number to send it to; on email check the response first: with more than one verified email and no `email_id` given, it answers 200 with `requires_email_selection: true` and `available_emails` — NO session was started and nothing was sent, so ask the user which address and call again with `email_id` rather than telling them to open a mailbox. Never hand `qr_text` to a link renderer — it is the link already rendered as QR art. Print it verbatim inside a fenced code block only when a real terminal needs the QR. (4) Call wait_for_2fa until the session is verified. (5) Retry the original sensitive call. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• start_add_emailwrite actionFree

  Start adding a new email address. Sends an OTP code to the email. Returns a session ID to verify with. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• start_add_phoneFree

  Start adding a new phone number. Uses reverse OTP: the system sends a message and the user replies. Returns a session ID, deep_link, qr_code (base64 PNG), and qr_text (UTF-8 text QR for terminal display). ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• start_domain_email_verificationwrite actionFree

  Start domain verification via corporate email. Sends a verification code to a standard admin email address at the domain. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• start_domain_verificationFree

  Start a B2B domain verification. Creates a verification record and returns DNS/HTTP instructions for the customer to complete. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• start_loginFree

  Start a login session by sending an authentication challenge to the user's chosen channel (Telegram, WhatsApp, SMS, or email). Returns a session ID and, FOR TELEGRAM AND WHATSAPP ONLY, deep_link, qr_code (base64 PNG) and qr_text (UTF-8 text QR for terminal display); on sms it returns sms_message with sms_dids instead, and on email nothing to display. Agent usage: (1) Call start_login with the desired channel and phone_number (for SMS) or email (for email). (2) Present the challenge, and WHICH FIELD depends on the channel. On telegram/whatsapp pass `deep_link` to render_auth_link, which prints the clickable link and a QR code; in a chat client the link is what the user acts on, since they are usually on the same machine. On sms `deep_link` is an EMPTY STRING and render_auth_link will reject it — show `sms_message` and let the user pick a number from `sms_dids`. `suggested_region` is always set, but the matching ENTRY in `sms_dids` may be missing (europe and israel appear only when a number is configured) or present with an empty `did`, so offer that region first only when `sms_dids[suggested_region]` exists and carries a number, and otherwise offer whatever the object does. On email there is nothing to display at all, and nothing to check either: a result means the mail was accepted for delivery, so tell the user to open their inbox. A delivery failure is an ERROR here, not a field — the tool answers `challenge_delivery_failed` and NO session exists, so do not call wait_for_login; retry, or offer another channel. Never hand `qr_text` to a link renderer — it is the link already rendered as QR art, so print it verbatim inside a fenced code block or not at all, because its rows stop scanning the moment one wraps or a blank line lands between them. (3) Call wait_for_login with the returned session ID to poll until the user completes authentication. Terminal states: "verified" (login succeeded), "failed", "expired".

• start_user_domain_verificationFree

  Start a self-service domain verification session. The user proves ownership of a domain via DNS or HTTP challenge. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• submit_verification_codewrite actionFree

  Submit an OTP/challenge code for a pending verification. Accepted ONLY where we delivered the code out-of-band to the party being verified: type "email", and type "domain" with channel "email". Any other pair answers 400 unsupported_for_type and completes elsewhere — use trigger_verification (POST /verifications/:id/verify) for a domain over dns/http/auto; a phone completes when the code reaches us FROM that number; social completes through its OAuth callback; a telegram_bot is already verified at creation. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• test_verifyFree

  Auto-complete a verification in test mode (pk_test_* API keys only). Useful for testing flows without real OTP delivery. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

Setting the first webhook endpoint creates the signing secret and returns it in this response; the value is returned only when this call created or rotated it, so record it then. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• update_templatewrite actionFree

  Create or update a custom template for a specific channel and message type. Replaces the default template. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• upload_hitl_keyswrite actionFree

  Upload an encryption keypair for a HITL config. The server validates the RSA-4096 public key and computes the key ID. Note: the encrypted_private_key is already encrypted client-side with the user's password — the server never sees the password. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• validate_proofFree

  Validate a proof token online. Checks the token signature, expiry, and revocation status against the server, and optionally that the proof is about the identifier you expect. Public endpoint — no API key required.

• verify_2fawrite actionFree

  Submit a verification code to complete a 2FA challenge. Rate limited to 10 attempts per minute. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• verify_2fa_magic_linkFree

  Complete a 2FA challenge using a magic link token (received via email). No code submission needed — the token itself is the proof. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• verify_delegationFree

  Verify a Proof of Delegation — the attestation that a domain authorized a specific agent artifact. Pass either the artifact's card (MCP server.json / A2A agent card) or a raw delegation token, PLUS two facts you established yourself: the artifact identity you resolved (the package you are installing, the endpoint you are calling) and the domain you expect to stand behind it. Both are required — a token can be copied into someone else's card, and any domain owner can mint a valid delegation naming someone else's package, so a verdict without both pins would mean 'some domain said something about some artifact'. WHERE THE IDENTITY MAY COME FROM: it is the artifact you are acting on, and never a value read from inside the artifact you are checking. A name in the artifact's own package.json, card or manifest is self-declared and editable by whoever ships it, so checking it against the delegation compares the artifact with itself. Resolve it afresh at call time instead of reusing a value from earlier in this conversation, which may already be stale. When no independently resolvable identity exists — a local or unpublished artifact — you have nothing to compare against, and that is the honest answer: report it rather than a mismatch, because a mismatch here reads as an accusation against the domain named in the delegation. The verifier walks signature → principal → delegate → revocation status, including the cascade down to the domain control proof. Requires no API key. What a verified result means: the expected domain's controller authorized this artifact for these scopes — NOT that the artifact is safe, audited or endorsed.

• verify_delegationsFree

  Batch-verify up to 50 Proof of Delegation artifacts in one call — the inventory half of the checker (h-proof-checker-mcp): re-check everything you already trust instead of one verify_delegation call per artifact. Each item takes the same shape verify_delegation requires (card XOR token, delegate, expected_principal, optional required_scopes) and follows the same rule about where identity comes from: each `delegate` is the artifact you are acting on, never a value read from inside the artifact you are checking, and resolved afresh at call time. Items are verified INDEPENDENTLY — no cross-item state, nothing persisted, one item failing never affects another item's result. This tool does NOT discover what you have installed and does NOT fetch anything on your behalf: it verifies material you already hold, the same trust boundary verify_delegation draws. Revocation is always checked (there is no check_status:false here — the point of a batch re-check is to see what changed since you last looked). Each result carries an `outcome`: confirmed_valid (verified), confirmed_invalid (a genuine negative verdict — revoked, expired, mismatched, malformed, and similar), no_claim_found (the artifact publishes no delegation at all — an absence, never an accusation), or unconfirmed (we could not reach the issuer or otherwise get a confident answer right now — NEVER treat this as a bad verdict). Requires no API key. `checked_at` on each result is the moment THAT item's own check completed, not one timestamp shared across the call.

• verify_domainFree

  Trigger domain verification. Checks DNS records or other verification method to confirm domain ownership. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• verify_domain_with_credentialsFree

  Verify a pending domain using previously stored DNS credentials. Use when credentials are already connected. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• verify_email_otpwrite actionFree

  Submit the OTP code to verify an email addition. Completes the add-email flow if the code is correct. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), or sign in with start_login — a session opens this tool — then call this tool again.

• wait_for_2faFree

  Poll a 2FA session until the user completes the challenge. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after start_2fa with the returned session_id. Terminal states: "verified" (challenge completed — proceed with the protected operation), "expired" (offer to restart with start_2fa). Before polling, present start_2fa's challenge: pass its `deep_link` to render_auth_link on telegram/whatsapp, or show its `sms_message` on sms. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• wait_for_account_creationFree

  Poll an account-bootstrap session until the user completes verification. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after create_account with the returned session id. Terminal states: "verified" (this server keeps the session for this connection; the `user_id` field in the terminal body identifies the authenticated user), "expired". A result with status "pending" means the wait ran out before the user finished — call this tool again with the same id. Works identically whether the underlying flow created a new User or logged in an existing one.

• wait_for_chat_id_discoveryFree

  Poll a chat ID discovery token until the user interacts with the Telegram bot. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after create_chat_id_discovery. Present the discovery response's `deep_link` with render_auth_link first, then poll with the returned token. Terminal states: "completed" (chat_id discovered — use it when creating a HITL config with a Telegram channel), "expired". While "pending", the user has not yet opened the Telegram link. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• wait_for_confirmationFree

  Poll a confirmation until the approver responds. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after create_confirmation with the returned confirmation ID. Terminal states: "approved" (action authorized — check the proof_token), "denied" (action rejected). While "pending", the approver has not yet responded. This poll returns no link — the approval request is delivered to the approver's own channel. If the approver needs one anyway, call get_confirmation_approval_link for a fresh `approval_url`; it needs the confirmation to be still pending — the state this tool waits in — and also refuses once `timeout_at` has passed, so a long wait can outlive the link even while the status has not moved. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• wait_for_loginFree

  Poll a login session until the user completes authentication. Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. Agent usage: Call this after start_login with the returned session ID. Terminal states: "verified" (login succeeded — this server keeps the session for this connection and signs your own account records with it: emails, phones, domains, API keys, 2FA, DNS credentials, verification requests, your public profile's username and proof list), "failed", "expired". A result with status "pending" means the wait ran out before the user finished — call this tool again with the same id.

• wait_for_requestFree

  Poll a verification request until it reaches a terminal state (completed, expired, or cancelled). Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• wait_for_sessionFree

  Poll a session until it reaches a terminal state (verified, failed, or expired). Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.

• wait_for_verificationFree

  Poll a verification until it reaches a terminal state (verified, failed, expired, revoked, or cancelled). Uses exponential backoff (2s initial, 1.5x, 30s max) with jitter. A multi-channel verification that lost the race is "cancelled" and one whose proof was withdrawn is "revoked"; both are final, so the wait returns rather than polling on. ACCESS: needs a Proof account. Authenticate this client (Claude Code: /mcp → Authenticate), then call this tool again. start_login does NOT open this tool.
