RECOMMENDED RULE

The rule that runs forget_credentials safely

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

forget_credentials Hidden

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