rudin_shapiro
The Rudin-Shapiro bit of n, the parity of the number of overlapping 11 blocks in its binary expansion. n = 3 is 11, so the bit is 1 and the sign is -1. n = 0 is 0. n runs from 0 to 1000000. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/...

Why rudin_shapiro is rated Low
Even though rudin_shapiro only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs rudin_shapiro safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rudin_shapiro, this is the rule to start with:
rudin_shapiro is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every rudin_shapiro call is checked against it from then on.
