Fixes

4 checks to fix

  1. Fails

    issuer equals the authorization_servers entry; token_endpoint_auth_methods_supported (ChatGPT)

    auth_chatgpt_metadata

    Blocks ChatGPT.

    Measured issuer "https://agentpixel.io/" is not exactly the authorization_servers entry "https://agentpixel.io"

    Use the exact metadata "issuer" string in the protected resource metadata authorization_servers list (no trailing-slash or case differences), and list token_endpoint_auth_methods_supported (for example ["none"] for public clients) in the au

  2. Warning

    Tool descriptions

    tool_descriptions

    Measured 1 under 60 chars: get_pixel

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

  3. Warning

    initialize latency

    latency

    Measured 1673 ms

    Bring initialize under 1.5 s: avoid cold starts and upstream calls in the handshake.

  4. Warning

    JSON-RPC error for unknown method

    jsonrpc_errors

    Measured JSON-RPC error -32602 instead of -32601

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