What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• ucode_render_home

  **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_services

  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_welcome

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

• ucode_session_status

  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_panel_ping

  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_agent_billing

  No login. Lists prepaid credit packs priced in USDC on Base for autonomous agents/bots (packageId, credits, usd, payTo). Buy one with **ucode_agent_buy_credits**. Signed-in humans pay by card at https://ucode.uk/app/credits instead (**ucode_render_credits**).

• ucode_instructions

  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_help

  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_connect

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

• ucode_login_start

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

• ucode_login_poll

  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_authenticate

  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_whoami

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

• ucode_disconnect

  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_sign_out

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

• ucode_credits_status

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

• ucode_render_credits

  Opens the **Add credits** card with the current wallet balance. Payments never happen in chat — the user taps through to **https://ucode.uk/app/credits**. After they add credits there, call **ucode_credits_status**. No payment details are collected in chat.

• ucode_credit_packages

  Same packs as **ucode_render_credits** (data). Prefer **ucode_render_credits**; credits are added on the Ucode website dashboard, never in chat.

• ucode_credit_gift_breakdown

  Free-credit badges / gift breakdown.

• ucode_credit_referral_stats

  Referral code and earnings summary.

• ucode_credit_referral_redeem

  Apply a friend's referral code (once per account, only if the referral program is active). Never guess, generate or loop over codes.

• ucode_payments_stripe_prices

  **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_create_checkout

  **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_verify

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

• ucode_payments_nowpayments_create

  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_status

  Poll invoice / payment status by NOWPayments id.

• ucode_credits_verify_app_store_purchase

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

• ucode_services_catalog

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

• ucode_sms_services

  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_countries

  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_prices

  **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_summary

  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_packa

• ucode_sms_service_detail

  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_rent_packages

  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_with_credits

  **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_rent_provider_direct

  **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_active_rentals

  Active/received rentals with SMS snippets if already fetched.

• ucode_sms_get_code

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

• ucode_sms_cancel_rental

  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_refund_expired

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

• ucode_sms_transactions

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

• ucode_app_init_snapshot

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

• ucode_find_numbers

  No sign-in needed. Search which apps/services (Telegram, WhatsApp, Google, OpenAI…) have virtual numbers in stock, by country, with the price in Ucode credits. Use this first whenever someone asks for a number or a price. Then: signed-in humans rent with ucode_sms_rent_packages →

• ucode_agent_quote

  Exact USDC (Base) price to rent ONE number for a service/country without prepaid credits. Use the 'service' code from ucode_find_numbers and a countryId.

• ucode_agent_buy_credits

  Autonomous agents: buy a prepaid credit pack with USDC on Base using the x402 protocol — no account or card needed. Step 1: call with {pack, acceptLawfulUse:true} (no paymentHeader) → returns PAYMENT_REQUIRED with exact x402 requirements. Step 2: sign that payment with your x402

• ucode_agent_rent

  Rent one virtual number for a lawful SMS verification. Pays from the agent wallet when a uc_live_ API key is active (from ucode_agent_buy_credits, ucode_agent_use_api_key, or an Authorization: Bearer uc_live_… header on the MCP connection). Without a key it uses pay-per-SMS: firs

• ucode_agent_check_sms

  Poll an agent rental for the SMS/OTP. Pass id and pollToken from ucode_agent_rent (or rely on the session API key).

• ucode_agent_wallet

  Credit balance of the agent wallet behind the active uc_live_ API key.

• ucode_agent_use_api_key

  Activate a previously issued uc_live_ agent API key for this MCP session (for clients that cannot set an Authorization header).

• ucode_agent_cancel

  Cancel an agent rental when no SMS arrived; credits return to the agent wallet. Requires the uc_live_ API key.
