MCP (Model Context Protocol) And Its Critical Vulnerabilities
Security Boulevard, Saturday, June 7th, 2025
Model Context Protocol connects AI assistants to external tools and data. Think of it as a bridge between Claude, ChatGPT, or Cursor and your Gmail, databases, or file systems.
Released by Anthropic in November 2024, it's gaining traction fast. But it has serious security problems.
What MCP Does
MCP lets AI models run tools and access data through a standard protocol. A typical setup looks like this:
AI Assistant (Client) <---> MCP Server <---> Your Tools/Data
The server exposes 'tools' - functions the AI can call.
