Continued fraction of a square root. sqrt(2) is [1; 2, 2, 2, ...] and the period is 1. sqrt(3) has period 2. A perfect square is one term and period 0.

What cf_sqrt does on ScorpTech x402 API
AI agents call cf_sqrt to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why cf_sqrt is rated Low
Even though cf_sqrt 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.

The rule that runs cf_sqrt 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 cf_sqrt, this is the rule to start with:
cf_sqrt 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 cf_sqrt call is checked against it from then on.
Questions about cf_sqrt
Continued fraction of a square root. sqrt(2) is [1; 2, 2, 2, ...] and the period is 1. sqrt(3) has period 2. A perfect square is one term and period 0. The period is the repeating length, even when fewer terms are requested. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/cf-sqrt. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
cf_sqrt accepts 2 parameters: s, count. Required: s. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for cf_sqrt: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ScorpTech x402 API. Nothing to install.
cf_sqrt is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the cf_sqrt rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for cf_sqrt. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
cf_sqrt is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
