About pipelock
Pipelock is an open source AI agent firewall written in Go and licensed Apache 2.0 that sits between AI agents and the network, inspecting mediated HTTP, WebSocket, MCP, and A2A traffic for secret exfiltration, prompt injection, SSRF, tool poisoning, and risky tool call chains, and emitting mediator signed action receipts so a reviewer can verify what the boundary decided from outside the agent runtime.
