RECOMMENDED RULE

The rule that runs install_from_source 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 install_from_source, this is the rule to start with:

install_from_source Rate-limited

install_from_source stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
