Fixes

8 checks to fix

  1. Fails

    readOnlyHint or destructiveHint on every tool

    tool_annotations

    Blocks Claude and ChatGPT.

    Measured 20/20 tools set neither readOnlyHint nor destructiveHint: multi_jurisdiction_search, federal_register_search, federal_register_document, sec_filing_search, sec_

    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 20/20 tools miss an explicit hint: multi_jurisdiction_search, federal_register_search, federal_register_document, sec_filing_search, sec_company_filings and 15

    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 20/20 without title: multi_jurisdiction_search, federal_register_search, federal_register_document, sec_filing_search, sec_company_filings and 15 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://tooloracle.io is not the server URL https://tooloracle.io/law/mcp/

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

  5. 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.

  6. 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.

  7. 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.

  8. Warning

    Tool descriptions

    tool_descriptions

    Measured 3 under 60 chars: federal_register_document, de_law_lookup, ping

    Keep each tool description between 60 and 2000 characters: when to use it, what it returns, key limits.
