Model Context Protocol is an open standard developed by Anthropic that defines how AI models connect to external tools, data sources, and services. Before MCP, every AI application required custom integration code for each tool the model needed to use: one integration for a database, another for a file system, another for a web browser. MCP standardizes this interface.
Any tool that implements the MCP server specification can be used by any MCP-compatible AI client without custom integration.
MCP is a universal connector. Tool implementation is decoupled from specific model integrations, so agent systems can share tools instead of rewriting them per model. This greatly reduces the engineering effort required to build agentic applications. A developer building an AI assistant can add MCP-compatible tools without writing new integration code for each one.
MCP is gaining adoption across the AI industry, with major development tools, databases, and services releasing MCP servers. It is becoming a foundational infrastructure layer for agentic AI systems. Anthropic open-sourced MCP in 2024 so tools, prompts, and data sources can speak one protocol to Claude, Cursor, and other hosts.
