MCP (Model Context Protocol)

An open standard for connecting AI models to local data sources, tools, and third-party APIs through a unified server-client architecture.

Anthropic introduced the Model Context Protocol (MCP) to solve the fragmentation between LLMs and isolated data silos. By replacing custom integrations with a standardized protocol, developers can build a single MCP server (using TypeScript or Python) that works across multiple IDEs like Claude Desktop and Cursor. This architecture enables models to securely query SQL databases, browse local file systems, or trigger GitHub actions without manual connector rewrites. It effectively turns static models into active agents capable of interacting with a user's entire local and cloud-based tech stack.
