The rule that runs memory_forget safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Hands, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For memory_forget, this is the rule to start with:
memory_forget 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 Mcp Hands, apply this rule, and every memory_forget call is checked against it from then on.
