Fixes

4 checks to fix

  1. Fails

    Human-readable title on every tool

    tool_titles

    Blocks Claude and ChatGPT.

    Measured 11/11 without title: zensched_guide, feedback_submit, account_create, account_signup_start, account_signup_verify and 6 more

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

  2. 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.

  3. Warning

    initialize latency

    latency

    Measured 1616 ms

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

  4. Warning

    JSON-RPC error for unknown method

    jsonrpc_errors

    Measured JSON-RPC error -32602 instead of -32601

    Return JSON-RPC error code -32601 (Method not found) for unknown methods.
