What Immune does

Immune — the agent security loop that turns every attack into an antibody. MCP firewall → replayable breach trace in ClickHouse → synthesized countermeasure → replay-proven → Semgrep rescan → signed receipt → ruling → the next agent is immune. Built at the Cyberdefense Hackathon, SF Tech Week 2026.

The agent security loop that turns every attack into an antibody.
An MCP firewall catches the attack. A remediator synthesizes the countermeasure, proves it by replaying the whole corpus in ClickHouse,
signs a receipt, publishes a ruling — and the identical attack bounces off the next agent, with a citation.
