client:ChatGPT transport:streamable-http tool:describe_data

Add Smarter Weather 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 describe_data does. ChatGPT lists the server's tools on connect and calls describe_data itself — you do not invoke it by name.

  3. 04

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

Smarter Weather will not start until these are set, so describe_data never becomes available.

  • SMARTERWEATHER_MCP_URL

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
