Model Context Protocol
The Model Context Protocol documentation explains a protocol for connecting models with external tools and data.
About Model Context Protocol
The Model Context Protocol (MCP) is described as an open-source standard for connecting AI applications to external systems: data sources such as local files and databases, tools such as search engines and calculators, and workflows including specialized prompts. This lets applications like Claude or ChatGPT reach outside information and carry out tasks, compared on the site to a USB-C port for AI applications. The site is documentation, with sections on architecture and security, guides for building servers, clients and MCP Apps, and a documentation index at /llms.txt.
Client and server support is stated across a range of AI assistants and development tools, including Claude, ChatGPT, Visual Studio Code, Cursor and MCPJam. Pricing and plan details are not listed, and the site's assistant generates responses using AI that may contain mistakes.
