RECOMMENDED RULE

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

get_scenario_yaml Allowed

get_scenario_yaml is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "get_scenario_yaml": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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