StoreStatusReason
Claude Connectors Directory Not ready Blocked by readOnlyHint or destructiveHint on every tool.
ChatGPT app directory Not ready Blocked by Sign-in method the store supports (OAuth or none), Protected resource metadata (RFC 9728), Authorization server metadata (RFC 8414 / OIDC), readOnlyHint or destructiveHint on every tool and Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT).
Gemini Connected Apps Not ready Blocked by Sign-in method the store supports (OAuth or none) and Authorization server metadata (RFC 8414 / OIDC).
Official MCP Registry Ready No blocking check failed.

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

Fixes

8 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 11/11 tools set neither readOnlyHint nor destructiveHint: generate_illustration, generate_logo, vectorize_image, get_task, wait_for_task and 6 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 ChatGPT.

    Measured Not found: https://cleanvector.ai/.well-known/oauth-protected-resource/api/mcp -> 404; https://cleanvector.ai/.well-known/oauth-protected-resource -> 404

    Serve RFC 9728 metadata at /.well-known/oauth-protected-resource (plus the path-suffixed form) with "resource" and "authorization_servers".

  3. Fails

    Authorization server metadata (RFC 8414 / OIDC)

    auth_as_metadata

    Blocks ChatGPT and Gemini.

    Measured Not found: https://cleanvector.ai/.well-known/oauth-authorization-server -> 404; https://cleanvector.ai/.well-known/openid-configuration -> 404

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

  4. Fails

    Sign-in method the store supports (OAuth or none)

    auth_method

    Blocks ChatGPT and Gemini.

    Measured unknown method: HTTP 401 and no working OAuth discovery: the server expects a credential such as an API key or static token

    ChatGPT and Gemini cannot send a static API key or token: add MCP OAuth (protected resource metadata and authorization server metadata), or serve the tools without auth. Claude accepts a static credential in a request header only in a beta

  5. Fails

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 11/11 tools miss an explicit hint: generate_illustration, generate_logo, vectorize_image, get_task, wait_for_task and 6 more

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

  6. Warning

    401 carries WWW-Authenticate resource_metadata

    auth_challenge

    Measured unknown method: WWW-Authenticate apikey without resource_metadata

    Add resource_metadata="https://<host>/.well-known/oauth-protected-resource<path>" to the WWW-Authenticate: Bearer header on 401.

  7. Warning

    Tool descriptions

    tool_descriptions

    Measured 1 under 60 chars: list_tasks

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

  8. 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.

13 checks passed, 6 did not run

Passed. Served over HTTPS, initialize over Streamable HTTP, Supported protocol version negotiated, JSON or SSE response Content-Type, GET answers SSE or 405, initialize latency, serverInfo name and version, Server instructions, tools capability declared, tools/list returns tools, inputSchema is an object schema, Tool names are valid and portable, Human-readable title on every tool.

Not run. Resource metadata "resource" equals the server URL, 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.
