The Model Context Protocol (MCP), introduced by Anthropic in November 2024, has rapidly emerged as the “USB-C port for AI Agents and applications” — revolutionizing how AI systems interact with external tools and data sources. This protocol standardizes the connection between Large Language Models (LLMs) and various services, enabling powerful agentic AI workflows. However, with this newfound capability comes a complex web of MCP threats and security challenges that organizations must navigate.
As MCP adoption accelerates across enterprise environments, security researchers and practitioners have identified numerous potential MCP Threats and attack vectors that could compromise systems, expose sensitive data, and undermine the trustworthiness of AI applications. From prompt injection attacks to tool poisoning, from credential theft to command injection, the MCP ecosystem presents a rich landscape of potential security risks.
