What is Model Context Protocol (MCP)?
The project demonstrates a security vulnerability in MCP (Model Context Protocol) servers that allows attackers to poison tools, leading to remote code execution and data exfiltration. The attack works by modifying server documentation to include malicious code, which is then executed by AI assistants. It uses tactics like base64 obfuscation, social engineering, and HTTP POSTs for data theft, emphasizing the importance of verifying MCP sources and securing AI development environments.
