Show HN: I built a 0.07ms Python firewall to stop AI hallucinations

Operating in show hn launch, I built a 0.07ms Python firewall to stop AI hallucinations operates.

Profile

Hey HN,I was building other AI products and kept hitting the same wall: agents hallucinate and constantly forget context. I ended up building a ledger just to track what they were actually doing.Once that ledger was logging everything, I realized I could use it to enforce rules. Exogram is the result. It is a deterministic firewall that intercepts agent tool calls (like MCP) using pure Python logic gates. It catches bad schemas and destructive actions in 0.07ms. There is zero AI in the security loop.I load-tested it yesterday and hit 137 RPS on a single container with zero dropped payloads.Sandbox: https://exogram.ai/proving-ground Repo: https://github.com/Richard-Ewing/exogram-protocol-rfcI
