ChatGPT Quickstart
Connect ChatGPT to FrankKi MCP. Start with a dryRun rehearsal: it is free and shows price and preview. A real send waits for your approval.
- Step 0
Your account
You can create it while connecting, in the sign-in window, or beforehand at /dashboard/registrieren. It is free, needs no invitation and no company.
- Step 1
Add FrankKi as a custom MCP server
In ChatGPT, add a custom MCP server with the URL below and OAuth as the authentication, then sign in to FrankKi in the window that opens (or create your account there). ChatGPT does not offer custom servers on every plan, and OpenAI has moved the menu during 2026. The current steps are in OpenAI's guide: https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt
Server URL: https://mcp.frankki.app Authentication: OAuth
- Step 2
Rehearse without sending
Ask your assistant to run mcp_health, then order_send with dryRun:true. The rehearsal is free and returns the price and page 1 as an image, without a letter, a charge or an approval. It needs a complete sender profile and the signed data processing agreement; mcp_health lists what is missing, with a link.
mcp_health({}) order_send({ "clientOrderId": "production-dry-run-001", "subject": "Connection check", "content": "This call only rehearses the send.", "recipientName": "Max Mustermann", "recipientStreet": "Musterstraße", "recipientHouseNumber": "1", "recipientZip": "10115", "recipientCity": "Berlin", "dryRun": true }) - Step 3
Send for real
Without dryRun the send waits for your approval in the FrankKi dashboard and is charged from your wallet once you approve. Top up from EUR 10 before the first real letter.
