Model Context Protocol

What is Model Context Protocol

The Model Context Protocol (MCP) is an open technical standard designed to facilitate seamless and secure communication between artificial intelligence models and external systems, including databases, APIs, and software tools. By acting as a standardized interface, MCP allows large language models (LLMs) and other AI-driven applications to access, retrieve, and manipulate external data or functionalities in a structured and predictable manner. This protocol bridges the gap between AI models and the broader digital ecosystem, enabling richer, more context-aware operations without the need for custom integrations on a per-application basis. As organizations increasingly rely on AI to automate processes and deliver insights, the Model Context Protocol provides a critical foundation for interoperability and extensibility, allowing developers, engineers, and technical leaders to build powerful hybrid systems. MCP plays a pivotal role in managing the flow of context between models and real-world data sources, streamlining the orchestration of complex workflows. The protocol empowers teams to unify disparate systems under a common standard, reducing friction and enhancing productivity. More information about its structure and adoption can be found at the Model Context Protocol Wikipedia entry.
