Mcp Watchdog

Mcp Watchdog is a security proxy for the MCP (Model Context Protocol) ecosystem, designed to protect AI assistants such as Claude, Cursor, and Windsurf from a wide range of advanced attacks targeting MCP servers. It sits between AI coding assistants and MCP servers, detecting and blocking over 40 classes of attacks—including prompt injection, tool poisoning, SSRF, reverse shell, SQL injection, token leakage, and more—before harmful data can reach the AI model. Zero-config and compatible with any MCP server, it supports macOS, Linux, and Windows, making it essential for developers, enterprises, and anyone running or interacting with MCP servers.
