WHAT IT DOES

What poly_eval does on ScorpTech x402 API

AI agents call poly_eval 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.

Parameter	Type	Required
`a`	array	Yes
`x`	integer	Yes
`mod`	string	—

Parameters from the server's own tool schema.

RISK

Why poly_eval is rated Low

Even though poly_eval 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

RECOMMENDED RULE

The rule that runs poly_eval 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 poly_eval, this is the rule to start with:

poly_eval Allowed

poly_eval is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "poly_eval": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every poly_eval call is checked against it from then on.

Questions about poly_eval

What does the poly_eval tool do? +

Evaluate an integer polynomial at an integer point, by Horner. The zero polynomial evaluates to 0. An optional modulus reduces the result; zero is rejected.

It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.

What parameters does poly_eval accept? +

poly_eval accepts 3 parameters: a, x, mod. Required: a, x. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on poly_eval? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for poly_eval: 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.

What risk level is poly_eval? +

poly_eval is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit poly_eval? +

Yes. Add a rate_limit block to the poly_eval 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.

How do I block poly_eval completely? +

Set action: deny in the PolicyLayer policy for poly_eval. 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.

What MCP server provides poly_eval? +

poly_eval 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.
