Model Context Protocol (MCP)

The Model Context Protocol (MCP) is an open standard for connecting AI applications to external data sources, tools, and workflows. It defines a consistent way for clients and servers to exchange context and capabilities, reducing the need for custom integrations between every model application and service. MCP can help make information and actions available to AI systems while keeping connections structured and explicit.

Open source tools in this area include server and client libraries, integrations for databases and services, development and debugging utilities, and gateways that coordinate multiple connections. When choosing a tool, consider its protocol support, maturity, maintenance activity, license, security model, runtime requirements, and compatibility with your existing AI applications. This area is useful to developers building AI agents, organizations integrating models with internal systems, and contributors creating reusable connections.
