ClawShield: Open-Source Firewall for AI Agent Communication

ClawShield is an open-source security firewall designed to protect agent-to-agent AI communication. It addresses the growing need for security as AI agents increasingly interact with each other. The firewall sits between AI agents and inspects every communication, blocking threats before they reach the infrastructure. It is built to protect OpenClaw instances but can work with any agent-to-agent protocol.

Key features include agent firewall capabilities with a configurable rule engine and threat scoring, prompt injection detection, skill static and dynamic analysis, credential leak detection, agent whitelisting, WebSocket protection, and encrypted communications. The architecture involves a proxy that intercepts requests, a rule engine with threat detection, and agent and skill analyzers. Every request undergoes a full inspection pipeline, and any failure or threat detection results in the request being blocked.

ClawShield's open-source nature allows for community contributions and continuous improvement. However, maintaining its effectiveness requires ongoing updates to threat signatures and analysis techniques. The setup process, involving Docker, PostgreSQL, and Redis, might be complex for some users.
