Fixes

7 checks to fix

  1. Fails

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 5/5 tools miss an explicit hint: get_latest_filing, list_filings, get_filing_toc, read_node_content, search_sec_event_filings

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

  2. 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.

  3. 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.

  4. Warning

    401 carries WWW-Authenticate resource_metadata

    auth_challenge

    Measured unknown method: WWW-Authenticate bearer without resource_metadata

    Add resource_metadata="https://<host>/.well-known/oauth-protected-resource<path>" to the WWW-Authenticate: Bearer header on 401.

  5. Warning

    Tool descriptions

    tool_descriptions

    Measured 1 over 2000 chars: search_sec_event_filings

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

  6. Warning

    initialize latency

    latency

    Measured 1752 ms

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

  7. Warning

    JSON-RPC error for unknown method

    jsonrpc_errors

    Measured HTTP 401 instead of a JSON-RPC error

    Route the method first and answer unknown methods with JSON-RPC error -32601 before the auth check, or return a JSON-RPC error body with the 401.
