ChatGPT Hermoso request_feature

How to: ChatGPT Hermoso request_feature

client:ChatGPT transport:streamable-http tool:request_feature

Add Hermoso to ChatGPT

  1. 01

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

https://app.hermoso.ai/mcp?src=registry
  1. 02

    Save the file and restart ChatGPT.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Hermoso'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

Set these first

Hermoso will not start until these are set, so request_feature never becomes available.

  • HERMOSO_TOKEN
  • HERMOSO_API_BASE

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.
