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.
Home (visual card) — **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.
Browse apps (visual picker) — 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.
Welcome (start here) — Same as **ucode_render_home** — product summary + sign-in card. Prefer **ucode_render_home** on first message.
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.
Panel API 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).
Agent credits (USDC on Base) — 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 user guide — 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 (AI) — 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.

Operate Ucode?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
— Starts browser sign-in for the visual card **Connect** button. Returns linkUrl + sessionId with uiView sign-in. Poll **ucode_login_poll** until linked.
Sign in with browser (recommended) — Creates a one-time browser sign-in URL. Prefer the in-card **Connect** button (**ucode_connect**). Poll **ucode_login_poll(sessionId)** until linked.
Finish browser sign-in — 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.
Link Ucode account (developer / mobile token only) — 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.
Who am I — Current linked Ucode user (requires ucode_login_poll complete or ucode_authenticate).
Disconnect from ChatGPT — 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.
Sign out — Same as **ucode_disconnect** — unlinks Ucode from this ChatGPT chat. Call for sign out, log out, or disconnect requests.
Credit balance — 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.
Buy credits (visual picker) — 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.
List credit packages — Same packs as **ucode_render_credits** (data). For ChatGPT humans prefer **ucode_render_credits** and the website dashboard. Agents: x402 USDC on Base.
Gift credits breakdown — Free-credit badges / gift breakdown.
Referral stats — Referral code and earnings summary.
Redeem referral code — Redeem a 6-character referral code for bonus credits.
Stripe price lookup — **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.
Create Stripe 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.
Verify Stripe checkout — After Checkout completes, pass checkout **session id** plus **packageId** so Panel credits the account.
Create crypto (NOWPayments) invoice — 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.
