RECOMMENDED RULE

The rule that runs remove_ssh_key safely

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

remove_ssh_key Hidden

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