    How to connect

    How to connect Tracepay to Claude

    The server address to paste into Claude settings:

    https://tracepay.ai/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Tracepay to ChatGPT

    The server address to paste into ChatGPT settings:

    https://tracepay.ai/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    trace_paymentUse this whenever you need to determine whether a supported stablecoin payment completed, failed, or is delayed — where the money currently is, who owns the next step, and what should happen next. Typical triggers: 'the recipient says the payment never arrived', 'this payout is stuck', 'did this transaction go through?'. Give it a Base transaction hash, Solana signature, Bridge transfer ID, Circle payment ID, or a Base/Solana wallet address (USDC). Trace correlates blockchain and provider evidence into one deterministic normalized state: completed/terminal flags, health, current stage and owner, an evidence-backed diagnosis code with a machine-readable suggested action and retry timing, and a knowledge model separating observed facts from inferences from what Trace cannot see (e.g. beneficiary bank credit — onchain finality never proves the recipient's bank credited funds; unknown never means failed). Public blockchain data works without authentication; provider-connected state requires an API key. If the user has no identifier, ask for a transaction hash, provider payment ID, or supported wallet address. Read-only: this tool never moves funds, retries payments, signs transactions, or guarantees beneficiary receipt — do not use it to send or swap anything. If a payment's state is unresolved, do NOT send a replacement payment; follow the returned warnings and suggested action instead.
    get_traceRetrieve an existing Trace payment trace by its trace_id (tr_...), including the stage timeline. Read-only. Same normalized representation as trace_payment.
    list_supported_systemsList what Trace supports and can do: assets (USDC), chains with public tracing (Base, Solana), providers requiring connected credentials (Bridge, Circle), and explicit capability flags (read-only; cannot send, retry, or sign). Call this when unsure whether a payment is in scope for trace_payment.
