MCP Servers
23 resources
The Model Context Protocol is a standard way to give an assistant access to a tool or data source, so the same server works across every client that speaks it. Everything here is free to use: an open-source licence on the repository, and no paid product or subscription needed for the server to do anything. Servers that exist to drive a metered API or a paid SaaS are left out — the note under each says what, if anything, you need. Star counts come from the GitHub API and are a snapshot, not a ranking.

MCP for Beginners
Microsoft's open-source MCP curriculum
A structured introduction to the protocol rather than reference docs — worth starting here if the SDK READMEs assume more than you have.
