Fixes

4 checks to fix

  1. Fails

    Human-readable title on every tool

    tool_titles

    Blocks Claude and ChatGPT.

    Measured 1/24 without title: introspection_prompt_library

    Add a short human-readable "title" to every tool (shown in store UIs and consent screens).

  2. Fails

    Resource metadata "resource" equals the server URL

    auth_resource

    Blocks Claude.

    Measured resource https://mcp.comos-federation.com is not the server URL https://mcp.comos-federation.com/mcp

    Serve metadata whose "resource" is exactly https://mcp.comos-federation.com/mcp (Claude requires an exact match, path included), e.g. at /.well-known/oauth-protected-resource/mcp.

  3. Fails

    Server instructions

    instructions

    Measured No instructions in the initialize result

    Add an "instructions" string to the initialize result: what the server covers, for whom, and its limits.

  4. Warning

    JSON-RPC error for unknown method

    jsonrpc_errors

    Measured JSON-RPC error -32000 instead of -32601

    Return JSON-RPC error code -32601 (Method not found) for unknown methods.
