RECOMMENDED RULE

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

delete_variable Hidden

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