What census_geographies does on ScorpTech x402 API
AI agents call census_geographies 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 |
|---|---|---|---|
lat | number | — | Alternative: latitude (with lon) |
lon | number | — | Alternative: longitude (with lat) |
address | string | — | One-line US street address with house number |
Parameters from the server's own tool schema.
Why census_geographies is rated Low
Even though census_geographies 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 census_geographies 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 census_geographies, this is the rule to start with:
census_geographies 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 census_geographies call is checked against it from then on.
