AI Conundrum: Why MCP Security Can't Be Patched Away

The report warns that integrating LLMs with the Model Context Protocol (MCP) creates new architectural attack surfaces—indirect prompt injection, tool poisoning, and "rug pull"—where malicious instructions embedded in content or tool metadata can cause LLMs to exfiltrate data or perform unauthorized actions; it recommends separating MCP servers for public/private data, scanning for instruction-like patterns and malicious metadata, enforcing least privilege, logging MCP traffic, building behavioral baselines, and keeping humans in the loop for sensitive actions.
