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

Fixes

5 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 4/17 tools set neither readOnlyHint nor destructiveHint: ask_arc, google_checkout_readiness, get_agent_facts, list_category_agent_facts

    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 6/17 tools miss an explicit hint: ask_arc, google_checkout_readiness, get_agent_facts, list_category_agent_facts, store_card and 1 more

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

  3. Fails

    Human-readable title on every tool

    tool_titles

    Blocks Claude and ChatGPT.

    Measured 17/17 without title: precheck, precheck_bulk, find_agent_ready_stores, can_agent_checkout, ask_arc and 12 more

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

  4. Fails

    Resource metadata "resource" equals the server URL

    auth_resource

    Blocks Claude.

    Measured resource https://arcreport.ai/api/mcp is not the server URL https://www.arcreport.ai/api/ask

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

  5. Fails

    GET answers SSE or 405

    get_stream

    Measured HTTP 200 application/json

    Return HTTP 405 Method Not Allowed on GET (or a text/event-stream), not a page or 404.
