Model Context Protocol — a USB-C connector that lets AI plug into everything. What it is, curated servers, and configuration guides.
What is MCP?
MCP (Model Context Protocol) is a standard open-sourced by Anthropic in November 2024 that solves a real problem: AI applications (desktop clients, IDEs and the like) need to connect to external tools and data sources (databases, GitHub, browsers…). Previously every tool had to be custom-built for each app; MCP turns this into a unified “USB-C interface”.
There are three roles: your AI application is the host, the MCP program providing a capability is the server, and they connect through the MCP protocol. Install a GitHub MCP server and your AI can manage repositories directly; install a browser MCP and your AI can operate web pages for you.
Today there are more than 15,000 MCP-related repositories on GitHub and nearly 10,000 officially registered servers — one of the most important pieces of infrastructure in the AI tool ecosystem.
Unified standard
Connect once, and any MCP-supporting AI can use it.
Extensible
Databases, search, automation, 3D… capabilities plug in and go.
Huge ecosystem
Close to 10,000 official plus community servers covering every scenario.
Open Settings → Developer → Edit Configuration (claude_desktop_config.json) and add the server config under the mcpServers field. Each server's specific parameters are in its project README — jump straight to them from this page.
