RECOMMENDED RULE

The rule that runs memory_unregister_type safely

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

memory_unregister_type Hidden

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