Ucode SMS MCP server

• ucode_agent_billingFree

  No login. Lists prepaid USDC (Base) credit packs for autonomous agents/bots and how to pay with x402. ChatGPT humans should use **ucode_render_credits** and https://ucode.uk/app/credits instead.

• ucode_app_init_snapshotFree

  Combined snapshot (packages, rentals, credit status, settings). Use platform web for ChatGPT (Stripe/crypto web packages); ios/android for native.

• ucode_authenticateFree

  Hidden escape hatch: only if the user explicitly already has a mobile Bearer token and asks to use it. Do NOT suggest this for normal sign-in — use ucode_login_start + ucode_login_poll instead.

• ucode_connectFree

  Starts browser sign-in for the visual card **Connect** button. Returns linkUrl + sessionId with uiView sign-in. Poll **ucode_login_poll** until linked.

• ucode_credit_gift_breakdownFree

  Free-credit badges / gift breakdown.

• ucode_credit_packagesFree

  Same packs as **ucode_render_credits** (data). For ChatGPT humans prefer **ucode_render_credits** and the website dashboard. Agents: x402 USDC on Base.

• ucode_credit_referral_redeemFree

  Redeem a 6-character referral code for bonus credits.

• ucode_credit_referral_statsFree

  Referral code and earnings summary.

• ucode_credits_statusFree

  Linked wallet — **credits** are in-app points for renting numbers, not a bank balance. Always say “you have X credits”. After a dashboard or x402 payment, call this so the ChatGPT card refreshes. Never imply USD wallet unless discussing listed pack prices.

• ucode_credits_verify_app_store_purchasewrite actionFree

  Server-side verify of RevenueCat / store purchase (same as mobile). Requires packageId, transactionId, productId, platform (iOS/Android), and purchaseToken for Android.

• ucode_disconnectFree

  Sign out / unlink this ChatGPT conversation from Ucode. Clears the MCP session only (not account deletion). Use when the user asks to sign out, log out, disconnect, or switch accounts. Shows the welcome card with **Connect** again.

• ucode_helpFree

  Optional natural-language help about Ucode features and flows. Uses the OpenAI key from Panel (Settings → ChatGPT App) when set, else OPENAI_API_KEY on the MCP host. Respects the “AI help” toggle in Panel.

• ucode_instructionsFree

  Full product guide (read-only). **Not for the first message** — use **ucode_welcome** first. If the user is not signed in, call **ucode_welcome** / **ucode_login_start** instead of answering rental questions. Official site https://ucode.uk.

• ucode_login_pollFree

  Poll after **ucode_login_start**. Links the ChatGPT session when the user has finished in the browser — **call repeatedly** until complete; do not ask users to paste tokens or to type “done” as the only completion signal.

• ucode_login_startwrite actionFree

  Creates a one-time browser sign-in URL. Prefer the in-card **Connect** button (**ucode_connect**). Poll **ucode_login_poll(sessionId)** until linked.

• ucode_panel_pingFree

  Public health check against Ucode Panel (no auth). Official downloads and info: https://ucode.uk — do not use unrelated domains (e.g. ucode.io).

• ucode_payments_nowpayments_createwrite actionFree

  Creates a crypto invoice (NOWPayments) for human web/Telegram top-ups. ChatGPT humans should use **https://ucode.uk/app/credits** instead. Autonomous agents/bots must pay **USDC on Base via x402**, not NOWPayments.

• ucode_payments_nowpayments_statusFree

  Poll invoice / payment status by NOWPayments id.

• ucode_payments_stripe_create_checkoutwrite actionFree

  **Do not use in ChatGPT.** In-card Stripe is blocked. For humans, call **ucode_render_credits** and open **https://ucode.uk/app/credits**. For agents/bots, call **ucode_agent_billing** and pay USDC on Base via x402.

• ucode_payments_stripe_pricesFree

  **Rare.** Resolve fiat display for Stripe IDs — do **not** read raw **prod_**/ **price_** strings to end users; use **ucode_credit_packages** for storefront-style copy.

• ucode_payments_stripe_verifyFree

  After Checkout completes, pass checkout **session id** plus **packageId** so Panel credits the account.

• ucode_render_creditsFree

  Opens the **Add credits** card with the current wallet balance. ChatGPT cannot run Stripe in the iframe — the user taps through to **https://ucode.uk/app/credits**. After they pay, call **ucode_credits_status**. Agents/bots should call **ucode_agent_billing** and pay USDC on Base instead of this tool.

• ucode_render_homeFree

  **Call on the first user message** in every new chat. Renders the interactive Ucode card with a **Connect Ucode account** button. Until linked, only welcome/connect/login tools — never rent or checkout.

• ucode_render_servicesFree

  Opens the **visual service picker** (popular apps + search). Call after sign-in or when the user wants a number — same data as **ucode_sms_summary** but optimized for the in-chat card.

• ucode_services_catalogFree

  Paginated Ucode service catalog with per-country availability from the Panel database.

• ucode_session_statusFree

  Check whether this ChatGPT session is linked to Ucode. Use at chat start; if connected is false, run **ucode_render_home** — do not process rental requests. If they already have a live number, the card shows it.

• ucode_sign_outFree

  Same as **ucode_disconnect** — unlinks Ucode from this ChatGPT chat. Call for sign out, log out, or disconnect requests.

• ucode_sms_active_rentalsFree

  Active/received rentals with SMS snippets if already fetched.

• ucode_sms_cancel_rentalwrite actionFree

  Cancel an active rental and refund credits when no SMS has arrived. Requires a cancel reason for analytics. Reasons: service_rejected | number_has_account | code_not_arrived | other. If an SMS arrives during cancel, credits stay charged and the code is returned.

• ucode_sms_countriesFree

  Raw worldwide country id table — pairs with legacy APIs only. For renting, use **ucode_sms_summary** / **ucode_sms_service_detail** so users pick by country name + credits.

• ucode_sms_get_codeFree

  Poll latest SMS for a rental id (provider rental id string).

• ucode_sms_pricesFree

  **Avoid for ChatGPT users.** Uses backend USD-ish snapshots; assistants must guide rentals via credits-only summaries (**ucode_sms_summary**, **ucode_sms_service_detail**) and **ucode_sms_rent_packages**. Responses are partially sanitized.

• ucode_sms_refund_expiredwrite actionFree

  Trigger server-side refund scan for expired rentals (same as app).

• ucode_sms_rent_packagesFree

  After user picks **serviceCode** + **country** (numeric id from summary/detail), list **credit-priced routes** only. Same package picker as the app (rentalFlowVersion 2). Present **credits**, recommended badge, labels — never quote USD or backend provider names.

• ucode_sms_rent_provider_directFree

  **Do not use for ChatGPT end users.** Legacy rental against upstream balances — skips normal credit UX and exposes provider-era assumptions. Only **ucode_sms_rent_with_credits** with packages.

• ucode_sms_rent_with_creditsFree

  **Primary rental** — charges Ucode credits. Always use **rentalFlowVersion: 2** and **packageId** from **ucode_sms_rent_packages** (matches mobile). Never mention wholesale/provider IDs or dollar amounts to the user.

• ucode_sms_service_detailFree

  Load one service’s countries after you have its short **serviceCode** (from summary `service` field). Matches opening that service in the iOS/Android app: availability, credits per country. Prefer over legacy `/prices` APIs.

• ucode_sms_servicesFree

  Low-level provider service codes — exposes internal naming. Do NOT use for normal rentals; prefer **ucode_sms_summary** or **ucode_sms_service_detail** then credits-only packages.

• ucode_sms_summaryFree

  Primary discovery: search by app/service name (e.g. Telegram, WhatsApp). Returns services with countries, **credits** only (no provider names / no USD in assistant copy). Same idea as the app Services tab. Then **ucode_sms_service_detail** or go straight to **ucode_sms_rent_packages** once service + country are chosen.

• ucode_sms_transactionsFree

  Provider ledger audit trail — sanitized before ChatGPT. Prefer explaining rentals via **ucode_sms_active_rentals** for users.

• ucode_welcomeFree

  Same as **ucode_render_home** — product summary + sign-in card. Prefer **ucode_render_home** on first message.

• ucode_whoamiFree

  Current linked Ucode user (requires ucode_login_poll complete or ucode_authenticate).
