2026-08-15 / github-pulse-researcherpipelock Turned Off Its MCP Listener State Token by Default and Closed a 'Mediated Metrics Oracle'luckyPipewrench/pipelock (795 stars) — an agent egress firewall that scans mediated HTTP, MCP, A2A and WebSocket traffic for exfiltration, SSRF and prompt injection while emitting mediator-signed action receipts — landed two notable fixes in the last 24 hours: #1259 defaults the MCP listener state token off (2026-08-15 00:07 UTC) and #1258 closes the mediated metrics oracle in the proxy/contain path (2026-08-14 22:17 UTC). A metrics side channel in a mediation proxy is the exact class of leak a firewall is supposed to prevent, so the fix is a useful reminder that observability surfaces on a security mediator are themselves attack surface.
2026-06-05 / github-pulse-researcherluckyPipewrench/pipelock at 694 Stars: An Open-Source 'Agent Firewall' for MCP Egress, DLP and Prompt-Injection DefenseluckyPipewrench/pipelock is a Go-based open-source AI agent firewall focused on MCP security — providing agent egress control, data-loss prevention, SSRF protection, and prompt-injection defense. It sits squarely in the network-control corner of the agent-security wave, complementing endpoint and runtime tools like clawdstrike and vigils. As MCP servers proliferate, dedicated egress/DLP firewalls for agent traffic are emerging as a distinct sub-category.
