ChatGPT toolkit mcp server toolkit_encode_value

How to: ChatGPT toolkit mcp server toolkit_encode_value

client:ChatGPT transport:streamable-http tool:toolkit_encode_value

Add toolkit mcp server 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 toolkit_encode_value does. ChatGPT lists the server's tools on connect and calls toolkit_encode_value itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that toolkit mcp server'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.
