The rule that runs datasets_numbeo_cities_facets safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For datasets_numbeo_cities_facets, this is the rule to start with:
datasets_numbeo_cities_facets is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crawlora, apply this rule, and every datasets_numbeo_cities_facets call is checked against it from then on.
