Store readiness

StoreStatusReason
Claude Connectors Directory Not ready Blocked by Resource metadata "resource" equals the server URL and readOnlyHint or destructiveHint on every tool.
ChatGPT app directory Not ready Blocked by readOnlyHint or destructiveHint on every tool and Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT).

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

4 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 8/8 tools set neither readOnlyHint nor destructiveHint: sign_up, complete_sign_up, search_brands, get_brand, list_brand_assets and 3 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

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 8/8 tools miss an explicit hint: sign_up, complete_sign_up, search_brands, get_brand, list_brand_assets and 3 more

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

  3. Fails

    Resource metadata "resource" equals the server URL

    auth_resource

    Blocks Claude.

    Measured resource https://motomarks.io is not the server URL https://motomarks.io/api/mcp

    Serve metadata whose "resource" is exactly https://motomarks.io/api/mcp (Claude requires an exact match, path included), e.g. at /.well-known/oauth-protected-resource/api/mcp.

  4. Warning

    initialize latency

    latency

    Measured 2151 ms

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