MCP (Model Context Protocol) lets your AI connect to external tools in real time. Here is how to set up your first MCP server.
MCP stands for Model Context Protocol. It is an open standard that lets AI models connect to external tools and services in real time. Think of it as USB ports for your AI — plug in any tool and your AI can use it natively.
Without MCP, your AI is isolated. It can only work with what is in its context window. With MCP, Claude Code can reach out to GitHub, query your database, search the web, send Slack messages, and interact with dozens of other services — all within the same conversation.
The easiest MCP server to start with is the GitHub MCP. Run: claude mcp add github -- npx -y @modelcontextprotocol/server-github. Once connected, you can ask Claude to read repos, create PRs, and manage issues without leaving your terminal.
The ecosystem includes 18+ MCP servers: GitHub, Slack, PostgreSQL, Apify (web scraping), SerpAPI (search), Google Drive, Browserbase (browser automation), Postman (API testing), and more. Each one adds a new capability to your AI brain.
