What is MCP Defender?
MCP Defender is a desktop application designed to automatically secure AI apps like Cursor, Claude, Visual Studio Code, and Windsurf from various attacks. It functions as an AI Firewall, monitoring and protecting Model Context Protocol (MCP) communications by intercepting tool calls and responses. It verifies these against security signatures and alerts the user if it detects any malicious activity, allowing them to block or allow the action. It provides intelligent LLM-powered threat detection and acts as a secure proxy, analyzing communications in real-time.
How to use MCP Defender?
MCP Defender is a desktop application that users download and install. Once active, it automatically acts as a secure proxy between your AI applications and MCP servers. It analyzes all communications for potential threats in real-time. If malicious activity is detected, it alerts the user, who can then choose to block or allow the action. It supports managing security signatures used during scanning.
