Store readiness

StoreStatusReason
Claude Connectors Directory Ready No blocking check failed.
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) 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

7 checks to fix

  1. Fails

    Protected resource metadata (RFC 9728)

    auth_prm

    Blocks ChatGPT.

    Measured Not found: https://mcp.mosadd.com/.well-known/oauth-protected-resource/mcp -> 404; https://mcp.mosadd.com/.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".

  2. Fails

    Authorization server metadata (RFC 8414 / OIDC)

    auth_as_metadata

    Blocks ChatGPT and Gemini.

    Measured Not found: https://mcp.mosadd.com/.well-known/oauth-authorization-server -> 404; https://mcp.mosadd.com/.well-known/openid-configuration -> 200

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

  3. Fails

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

    auth_method

    Blocks ChatGPT and Gemini.

    Measured GET: HTTP 401 and no working OAuth discovery: the server asks for a Bearer token but its OAuth metadata could not be found

    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

  4. Fails

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 85/103 tools miss an explicit hint: mDM_list_contacts, mDM_publish_keys, mDM_send, mDM_send_unencrypted, mDM_list and 80 more

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

  5. Fails

    Server instructions

    instructions

    Measured No instructions in the initialize result

    Add an "instructions" string to the initialize result: what the server covers, for whom, and its limits.

  6. Warning

    401 carries WWW-Authenticate resource_metadata

    auth_challenge

    Measured GET: WWW-Authenticate bearer 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 4 under 60 chars: mIRC_list, mIRC_get, mIRC_unban, mAYL_view

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

14 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, tools capability declared, tools/list returns tools, inputSchema is an object schema, Tool names are valid and portable, readOnlyHint or destructiveHint on every tool, 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.
