Model Context Protocol (MCP) is an open standard developed by Anthropic for connecting AIArtificial Intelligence - technology that enables machines to perform tasks that normally require human intelligence, such as language understanding, pattern recognition, and decision-making. models to external systems. MCP defines a common interface between a "host" (the AI client, e.g. Claude CodeAnthropic's AI coding assistant - integrated into the terminal and IDEs for agentic software development.) and a "server" (the tool or data source). This makes it possible to build modularArchitecture or design principle where systems are built from independent, interchangeable components., reusable integrations that work across different AI models and applications.
