Open-Source MCP Security Gateway

Zero-Trust Security for AI Agents.

An ultra-fast, Rust-powered MCP gateway that inspects payloads, blocks prompt injections, and secures your tool servers in <10ms.

How It Works

Sits between your agents and tools

Every MCP request passes through Navil's inspection engine before reaching your tool servers.
