MCP Registry ready means a valid public remote for the registry, not that the server is listed in a store.

Fixes

4 checks to fix

  1. Fails

    Protected resource metadata (RFC 9728)

    auth_prm

    Blocks Claude and ChatGPT.

    Measured https://satohub.ai/.well-known/oauth-protected-resource/api/mcp has no authorization_servers

    List your issuer URL in "authorization_servers" in the protected resource metadata.

  2. Fails

    Authorization server metadata (RFC 8414 / OIDC)

    auth_as_metadata

    Blocks Claude, ChatGPT and Gemini.

    Measured No authorization server to probe

    Serve RFC 8414 metadata at <issuer>/.well-known/oauth-authorization-server with authorization_endpoint, token_endpoint and response_types_supported ["code"].

  3. Fails

    initialize latency

    latency

    Measured 4590 ms

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

  4. Warning

    Tool descriptions

    tool_descriptions

    Measured 20 over 2000 chars: onchain_agent_search_resources, onchain_agent_get_deploy_spec, onchain_agent_search_agents, onchain_agent_recommend_stack, onchain_agent_get

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