What getCarFacets does on API Ninjas

Why getCarFacets is rated Low
Even though getCarFacets 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 getCarFacets safely
PolicyLayer is an MCP gateway: it sits between your AI agents and API Ninjas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getCarFacets, this is the rule to start with:
getCarFacets 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 API Ninjas, apply this rule, and every getCarFacets call is checked against it from then on.
