Introducing the Model Context Protocol
by Anthropic
The original announcement that launched MCP.
Overview
Published November 25, 2024, this is Anthropic's announcement open-sourcing the Model Context Protocol, described as a new standard for connecting AI assistants to the systems where data lives. It frames the core problem MCP solves: fragmented, custom-built integrations (the NxM problem) between AI models and data sources, and how a single universal protocol replaces them. The post introduces MCP servers (which expose data) and MCP clients (AI applications that consume it), and covers the launch components: technical specifications and SDKs on GitHub, Claude Desktop local server support, and pre-built servers for popular systems like Google Drive, Slack, GitHub, Git, and Postgres. It cites early adopters including Block, Apollo, Zed, and Replit.
