RECOMMENDED RULE

The rule that runs slack_unlink_user safely

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

slack_unlink_user Hidden

slack_unlink_user 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 Munin, apply this rule, and every slack_unlink_user call is checked against it from then on.
