RECOMMENDED RULE

The rule that runs snapshot_host safely

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

snapshot_host Rate-limited

snapshot_host stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
