jeffrschneider · reddit · 2026-07-30
A Reddit user seeks recommendations for an agent-to-agent gateway that intercepts messages between untrusted agents to prevent poisoned messages. Requirements include A2A protocol support, streaming and non-streaming, policy-oriented, fast and cheap with high F1, and ability to detect poisoned references (e.g., URLs pointing to prompt injections). Prefers open-source but considers commercial solutions.
