Fixes

3 checks to fix

  1. Fails

    Explicit readOnlyHint, destructiveHint and openWorldHint (ChatGPT)

    tool_open_world

    Blocks ChatGPT.

    Measured 70/71 tools miss an explicit hint: token_price, wallet_profile, token_risk_score, transaction_parse, whale_alert and 65 more

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

  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 3121 ms

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