Show HN: Wardline, a Go proxy that auto-blocks compromised AI agents
The control-plane proxy that auto-blocks compromised AI agents — in one static Go binary. Wardline is an open-source proxy that sits between your AI agents and everything they call (MCP servers, tools, gRPC upstreams) and enforces identity, policy, budget, and audit — with statistical anomaly detection that blocks a compromised agent in real time, no rule written for the attack and no human in the loop. Key Features Real-time anomaly auto-block Four self-baselining heuristics (rate spike, novel tool, deny-rate spike, and a combined ml_score z-score via Welford's algorithm — no training data, no external model) that don't just alert: auto_block rejects a flagged identity's calls for a bounded TTL.

One static Go binary; no database, IdP, or sidecar to start. make demo # spins up a mock MCP server + Wardline and runs the scenario above The same run in the built-in read-only dashboard — the block, the anomaly that triggered it, and the policy behind it: How it works Any caller — an AI agent, a CLI/IDE, or an app — reaches its MCP/gRPC upstreams only through Wardline, which applies…
