Fixes

6 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 18/18 tools set neither readOnlyHint nor destructiveHint: catalog, list_suites, read_suite, enter_open_challenge, start_challenge and 13 more

    Set annotations.readOnlyHint: true on read-only tools and destructiveHint: true on tools that modify or delete data (Claude needs one of them on every tool; ChatGPT needs all three hints, see tool_open_world).

  2. Fails

    Protected resource metadata (RFC 9728)

    auth_prm

    Blocks Claude and ChatGPT.

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

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

  3. 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"].

  4. Fails

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 18/18 tools miss an explicit hint: catalog, list_suites, read_suite, enter_open_challenge, start_challenge and 13 more

    Set readOnlyHint, destructiveHint and openWorldHint to explicit true/false on every tool (OpenAI app review requires all three).

  5. Fails

    Human-readable title on every tool

    tool_titles

    Blocks Claude and ChatGPT.

    Measured 18/18 without title: catalog, list_suites, read_suite, enter_open_challenge, start_challenge and 13 more

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

  6. Warning

    Tool descriptions

    tool_descriptions

    Measured 2 under 60 chars: read_card, fetch

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

15 checks passed, 6 did not run

Passed. Served over HTTPS, initialize over Streamable HTTP, Supported protocol version negotiated, JSON or SSE response Content-Type, JSON-RPC error for unknown method, GET answers SSE or 405, initialize latency, serverInfo name and version, Server instructions, tools capability declared, Sign-in method the store supports (OAuth or none), Resource metadata "resource" equals the server URL, tools/list returns tools, inputSchema is an object schema, Tool names are valid and portable.

Not run. 401 carries WWW-Authenticate resource_metadata, First metadata URL Gemini tries answers 200 with the required fields, issuer equals the authorization_servers entry; token_endpoint_auth_methods_supported (ChatGPT), PKCE S256 advertised, Client registration (DCR or Client ID Metadata Documents), refresh_token grant advertised. These need an OAuth sign-in flow the check could not reach.
