Add Multi Mail to ChatGPT

  1. 02

    Save the file and restart ChatGPT.

  2. 03

    Ask for something threads_archive does. ChatGPT lists the server's tools on connect and calls threads_archive itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Multi Mail's identifier in your config matches the one above exactly.

Custom connectors are a paid-plan feature and take a remote URL only. ChatGPT cannot run a packaged server locally. ChatGPT docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
