The Security Gap in MCP: The Hidden Risks No One Is Talking About

The Model Context Protocol (MCP) is gaining attention for its ability to provide standardized access for large language models (LLMs) to various tools and systems, simplifying integration and enhancing capabilities. However, the lack of contextual grounding and security measures poses significant risks when using MCP, as LLMs may misuse tools, escalate privileges, or become confused by schema without proper guidance. The article emphasizes the importance of providing a structured understanding of the business environment, using graph-based approaches like GraphRAG to encode relationships and constraints, thereby reducing the potential for errors and security breaches. The author predicts that security will be the main obstacle to MCP adoption, with enterprises needing to build context before integrating capabilities to ensure safer workflows. Memgraph has developed tools to support MCP adoption by providing the necessary context, highlighting the need for a grounded approach when deploying LLMs in live systems.
