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