MCP Free Servers: Open Source Options List
A community-maintained directory of free, open-source MCP servers by category, with license and maintenance-status notes.
Free resource directoryMaintenance status flags
Most of what a new MCP project needs already exists as a free, open-source server. This list is organized by category so you're not paying for something the community already built.
Checking Before You Adopt
- Confirm the license permits your use case (MIT and Apache-2.0 dominate; a few are source-available only)
- Check the last commit date — MCP moves fast, and abandoned servers often predate breaking spec changes
- Read the tool schemas before installing, not just the README — descriptions vary wildly in quality
