Attacks that exploit this kind of access
The rule that runs nrel.afdc.search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For nrel.afdc.search, this is the rule to start with:
nrel.afdc.search 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 Apibase, apply this rule, and every nrel.afdc.search call is checked against it from then on.
