MCP Dandan

MCP-Dandan is an open-source desktop security solution designed to monitor Model Context Protocol (MCP) communications and provide multi-layered, real-time threat detection and defense. Featuring an Electron-based cross-platform UI, it integrates five detection engines—covering command injection, file system exposure, PII leak, data exfiltration, tools poisoning, and more—combining both signature and LLM-based semantic analysis. MCP-Dandan is ideal for security-conscious developers, teams, and organizations using the MCP ecosystem who require real-time monitoring, advanced threat detection, and easy management across Windows, macOS, and Linux.
