Security Firewall for Agents — Ryan Dahl, Deno

Deno addresses the critical security challenge of AI agents with production write access by introducing Claw Patrol. This MIT-licensed proxy operates below the HTTP layer, deep inspecting all agent communications (including non-HTTP protocols), enforcing granular HCL-based rules, and handling credential injection. It allows for human or LLM approval workflows, ensuring robust, external security against prompt injection and malicious actions, as agents are fundamentally considered untrusted software.
