Model Context Protocol (MCP) is Anthropic's open protocol for connecting Claude to external tools, integrated with the Claude 4 API.

Summary

There is a standardized, open protocol called MCP that lets developers wire Claude up to outside tools and data sources directly through the Claude 4 API, rather than building custom one-off integrations. Because it is open, any developer can build compatible tools, which means the ecosystem of things Claude can do can grow without Anthropic having to ship every integration itself.
