The best MCP servers in 2026
The MCP servers most worth connecting are the official ones for tools you already use: Caddie (your notes, tasks, calendar and meeting transcripts), GitHub (issues, pull requests and code), Playwright (a browser your agent can drive), Context7 (current docs for the libraries you code with), Notion (your pages and databases) and Linear (issues and projects). Start with two or three; every server you add is more your agent can read, and more to keep scoped.

Why people look for something better
An agent is only as useful as what it can reach. MCP servers give Claude, ChatGPT, Cursor and coding agents your real tools and data, safely and with your permission.
