The protocol layer
Every MCP server worth installing.
The Model Context Protocol (MCP) is how AI assistants connect to your tools, data, and workflows. Each server below extends what Claude (or any MCP-compatible agent) can do — read your filesystem, query your databases, post to Slack, manage your Notion. Hand-picked by working professionals.
New to MCP?
Think of MCP servers as plugins for AI assistants. You install one, give your assistant permission to use it, and the assistant can now read files, run SQL queries, or post messages — whatever the server exposes. Anthropic shipped the open standard in 2024; the ecosystem has grown fast since. See the official MCP docs for the technical spec.
