RISK

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs wps_clear_cache safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Wps, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wps_clear_cache, this is the rule to start with:

wps_clear_cache Hidden

wps_clear_cache is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
