Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnrandom_int_signed

    The server marks "random_int_signed" as not read-only (readOnlyHint: false), and its words say it reads.

    Matched text

    annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "return": a word for reading.

    Description, as the server wrote it
    Return a uniformly distributed random integer in [min, max] with the same drand quicknet provenance as random_int, plus a payment receipt. Costs $0.01 per call in stablecoin over the Machine Payments Protocol. New unpaid challenge requests are safety-limited. An unpaid call answers with a payment challenge (JSON-RPC -32042); a client that cannot pay should use random_int instead.

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Return a uniformly distributed random integer in [min, max], derived from a signature-verified drand quicknet beacon mixed with a server secret and, when a public KiwiSDR receiver delivers one, a hash of live HF atmospheric noise. The response carries the drand round, the beacon signature, a per-request nonce, a commitment hash binding them to the value, a URL where the round can be re-verified, and a `physical` block stating whether noise went in and from where. Free and rate-limited.

    Annotations the server declares

    • title: Free verified random integer
    • readOnlyHint: true
    • openWorldHint: true
  • statusReport service and beacon health: the current drand quicknet round, which relay answered, the rate-limiter mode, and whether the last draw obtained live atmospheric noise.No findings

    Why it is in this group

    • The name "status" says "status": a word for reading.
    Description, as the server wrote it

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as truerandomness. Review it before you use it.
