Fixes

3 checks to fix

  1. Fails

    Resource metadata "resource" equals the server URL

    auth_resource

    Blocks Claude.

    Measured resource https://mcp.asterwise.com is not the server URL https://mcp.asterwise.com/mcp

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

  2. Warning

    Tool descriptions

    tool_descriptions

    Measured 1 over 2000 chars: asterwise_get_western_natal

    Keep each tool description between 60 and 2000 characters: when to use it, what it returns, key limits.

  3. Warning

    JSON-RPC error for unknown method

    jsonrpc_errors

    Measured HTTP 401 instead of a JSON-RPC error

    Route the method first and answer unknown methods with JSON-RPC error -32601 before the auth check, or return a JSON-RPC error body with the 401.
