behrensd/mcp-firewall

Developer Tools

Deterministic security proxy (iptables for MCP) that intercepts tool calls, enforces YAML policies, scans for secret leakage, and logs everything. No AI, no cloud.

Overview

Direct install

Run the underlying MCP server directly — without Agent-CoreX routing.

npx -y mcp-firewall
