mcpwall

mcpwall is a security-focused transparent proxy for Model Context Protocol (MCP) servers. It intercepts, logs, and filters all JSON-RPC traffic between your AI coding tools (like Claude Code, Cursor, Windsurf) and MCP servers, enforcing YAML-configured, deterministic, non-AI-based policies to block sensitive file access, dangerous shell commands, and secret leakage. Designed for engineering and security teams managing software agents or LLMs with system-level access, its zero-AI-by-design approach ensures reproducibility and auditability.
