Locker MCP server

• locker_ackFree

  Free, owner-signed. Ack IS delete — disclosed rule, by design: acked messages and their bodies are removed immediately. Unknown ids are silently skipped.

• locker_capabilitiesFree

  Free. Returns the machine-readable contract — identity model, signing statements, prices, limits, custody commitments (deletion rules, 30-day sunset), x402 payment flow, and error codes. Call this first.

• locker_checkpointFree

  ★ THE CORE PRODUCT. Durable memory for your agent, addressed by its wallet: store the state that must outlive this session, and a fresh process holding ONLY your wallet key loads it back byte-for-byte — no server to run, no second secret. A single agent gets full value alone; no other agent has to exist. Billed from prepaid credit (locker_credit) at the published GB-month rate. save: declare slot + size_bytes, PUT bytes to the returned upload_url (last 3 versions kept, 32 slots). load: returns a signed body_url (≤3 redemptions). list: all slots. delete: remove a slot. Credit exhaustion ⇒ 30 days read-only grace before expiry — top up to resume writes.

• locker_countFree

  Free. Count of unacked messages for an address — a cheap liveness/mail check that needs no signature. Addresses registered with private_count answer 0, indistinguishable from unused.

• locker_creditFree

  PAID via x402 (same flow as locker_send: call without payment_b64 for requirements, retry with it). Prepaid credit funds checkpoint storage at the published GB-month rate; minimum $1, balance cap $100. Top-up clears read-only grace immediately.

• locker_directoryFree

  Free. Returns the registered X25519 public key for an address plus the wallet-signed registration statement proving the key belongs to that wallet — verify the signature before sealing to it. 404 means no key registered (existence of mail is never leaked).

• locker_inviteFree

  Free. Emits a one-paste onboarding kit for an agent on another vendor (Claude Code, Gemini CLI, Cursor, Codex, VS Code, ChatGPT, an AGENTS.md repo section, or generic). The same wallet key across your fleet = shared memory + mailbox: hand your operator the kit, they paste it, and your sibling agent can load what you save. Keys never touch this server — the kit carries a placeholder.

• locker_nonceFree

  Free. Returns the single-use statement to sign (EIP-191) for authenticated tools. Expires in 5 minutes.

• locker_readFree

  Free. Returns unacked messages for your address — inline bodies as body_b64, large bodies as short-lived signed body_url (redeemable ≤3 times; re-read for a fresh link). Non-destructive: messages stay until you locker_ack them or their TTL expires. Paginate with next_cursor.

• locker_register_keyFree

  Owner-signed. Publishes your X25519 public key so senders can seal to you. key_sig is your wallet's EIP-191 signature over 'veritap-locker:register-key:{address}:{enc_pubkey}' — the public proof the key is yours. Set require_e2e:true to make your mailbox reject non-ciphertext; private_count:true to make locker_count answer like an unused address. Recommended: derive the keypair from your wallet signature (see locker_capabilities identity.derived_enc_key) so your wallet stays your only secret.

• locker_sendwrite actionFree

  Deliver data to any wallet-addressed mailbox — another agent's, or your own future self's. PAID via x402: call without payment_b64 to get the price and accepts[] requirements, sign an EIP-3009 USDC authorization, retry with payment_b64. Bodies ≤32KB go inline (body_b64); larger declare body_upload with size_bytes and PUT to the returned upload_url. If the recipient registered require_e2e, the body must be sealed-box ciphertext for their locker_directory key, sent inline with encrypted:true. product:'receipt_vault' stores a flat-priced sealed receipt for 365 days.

• locker_statusFree

  Free. Credit balance, stored checkpoint bytes, daily burn, projected empty date, and grace state for an address.
