The rule that runs uro_url_filtering safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For uro_url_filtering, this is the rule to start with:
uro_url_filtering 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 Nyxstrike, apply this rule, and every uro_url_filtering call is checked against it from then on.
