Store readiness

StoreStatusReason
Claude Connectors Directory Not ready Blocked by Resource metadata "resource" equals the server URL.
ChatGPT app directory Unverified Nothing failed, but tools/list returns tools, inputSchema is an object schema, readOnlyHint or destructiveHint on every tool, Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT) and Human-readable title on every tool could not run in a check without credentials.
Gemini Connected Apps Unverified Nothing failed, but Supported protocol version negotiated, tools/list returns tools and inputSchema is an object schema could not run in a check without credentials.
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

2 checks to fix

  1. Fails

    Resource metadata "resource" equals the server URL

    auth_resource

    Blocks Claude.

    Measured resource https://mcp.marcora.ai is not the server URL https://mcp.marketcore.ai/

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

  2. Warning

    initialize latency

    latency

    Measured 2634 ms

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