client:ChatGPT transport:streamable-http tool:create_project_token

Add EchoRelay to ChatGPT

  1. 01

    Open Settings → Connectors → Advanced → Developer mode and merge this in. Keep any servers already there.

  1. 02

    Save the file and restart ChatGPT.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that EchoRelay'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 24 September 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.
