WHAT IT DOES

RECOMMENDED RULE

The rule that runs compose_music safely

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

compose_music Rate-limited

compose_music 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.

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect Libi, apply this rule, and every compose_music call is checked against it from then on.
