Fixes

7 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 10/10 tools set neither readOnlyHint nor destructiveHint: search_creators, list_schedule, find_overlaps, inventory_snapshot, get_profile and 5 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 10/10 tools miss an explicit hint: search_creators, list_schedule, find_overlaps, inventory_snapshot, get_profile and 5 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 10/10 without title: search_creators, list_schedule, find_overlaps, inventory_snapshot, get_profile and 5 more

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

  4. 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.

  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.

  6. Warning

    Supported protocol version negotiated

    protocol_version

    Measured Negotiated 2025-03-26

    Support protocol version 2025-11-25 (or 2025-06-18) and echo it back in initialize.

  7. Warning

    initialize latency

    latency

    Measured 1739 ms

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