RECOMMENDED RULE

The rule that runs list_source_templates safely

list_source_templates Allowed

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

}

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 list_source_templates call is checked against it from then on.
