What treasury_rates does on ScorpTech x402 API
AI agents call treasury_rates 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 | Description |
|---|---|---|---|
date | string | — | As-of date YYYY-MM-DD (latest published on or before it); default latest |
debt | boolean | — | Include Debt to the Penny (default true) |
curve | string | — | nominal (default), real, both or none |
Parameters from the server's own tool schema.
Why treasury_rates is rated Low
Even though treasury_rates 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 treasury_rates 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 treasury_rates, this is the rule to start with:
treasury_rates 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 treasury_rates call is checked against it from then on.
