The rule that runs revoke_api_key safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Agentpay, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For revoke_api_key, this is the rule to start with:
revoke_api_key is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Agentpay, apply this rule, and every revoke_api_key call is checked against it from then on.
