Fixes

5 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 22/22 tools set neither readOnlyHint nor destructiveHint: ad_get_build_options, ad_register, ad_get_me, ad_create_character, ad_list_live_tables and 17 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 22/22 tools miss an explicit hint: ad_get_build_options, ad_register, ad_get_me, ad_create_character, ad_list_live_tables and 17 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 22/22 without title: ad_get_build_options, ad_register, ad_get_me, ad_create_character, ad_list_live_tables and 17 more

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

  4. 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.

  5. Warning

    initialize latency

    latency

    Measured 3842 ms

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

12 checks passed, 10 did not run
