WHAT IT DOES

What farey_child does on ScorpTech x402 API

AI agents call farey_child 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`	integer	Yes
`b`	integer	Yes
`c`	integer	Yes
`d`	integer	Yes

Parameters from the server's own tool schema.

RISK

Why farey_child is rated Low

Even though farey_child 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 farey_child 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 farey_child, this is the rule to start with:

farey_child Allowed

farey_child 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": {
    "farey_child": {}
  }
}

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 farey_child call is checked against it from then on.
