Recorded software licenses
Best open-source mcp servers
Projects with recognized open-source software licenses recorded in the mcp servers index, ordered by recorded GitHub star count. Stars measure repository interest, not task performance, active users, or maintenance quality. Use this list to compare options, then check each project’s current license, activity, model requirements, and operating costs. Sponsorship never affects the order. Right now it's led by MCP Reference Servers (91k stars), with context7 and chrome-devtools-mcp following. Order follows the recorded star counts; repository activity is shown separately.

Frequently asked
- What are the best open-source mcp servers?
- Use the projects below as a comparison list ordered by recorded GitHub stars. A higher star count does not establish the best fit or prove continued maintenance; compare the project’s capabilities, license, and current activity for your task.
- Are open-source mcp servers free?
- An open-source software license does not make an entire deployment free. Check the license and any hosting, model, API, or managed-service costs; some projects require external accounts or providers.
- Open-source or commercial mcp servers — which should I choose?
- Compare source access, license obligations, deployment options, data handling, support, and total costs. An open-source client may still use a hosted model or service. Both open-source and commercial options appear in the full mcp servers category.
