  1. 02

    Save the file and restart Claude.ai.

  2. 03

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

  3. 04

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

Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai 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.
