Cedar's constraint model — no unbounded loops, explicit attribute types, mathematically verifiable policies — beats OPA/Rego for agent tool access control where a policy bug could allow unintended execution. Cedar Analysis can formally prove policies are correct before deployment. CNCF Sandbox status. Use Cedar for safety-critical MCP policies; keep OPA for complex operational logic. Natoma
