Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~1,744Tokens (tool definitions)
~5.9 KBTypical response size
Moderate attention impact (1.36% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢random_int(min, max)
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.

}⚪random_int_signed(min, max, requestId)
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.
