Model Context Protocol (MCP): The Next Big Thing for LLM Integration—But With a Catch

Model Context Protocol (MCP) is emerging as the standard for Large Language Model (LLM) integration with tools and data, dubbed the "USB-C for AI agents." It enables agents to connect to tools via standardized APIs, maintain persistent sessions, run commands, and share context across workflows. However, MCP isn't secure by default. Connecting agents to arbitrary servers without careful consideration can create security vulnerabilities, potentially exposing shell access, secrets, or infrastructure via side-channel attacks.
