FAQ
How is this ranking computed?
Entries are ordered by GitHub stars, which remains the strongest single adoption signal in the MCP and Agent Skill ecosystem. On each detail page you can also compare quality and trend scores that factor in documentation completeness and recent commit activity.
Are these MCP servers free to use?
The servers themselves are open source — check the license shown on each detail page. Note that some servers act as clients to paid APIs (for example hosted search or database services), where the underlying service may bill you separately.
Which clients work with these servers?
All servers listed here speak the standard Model Context Protocol, so they work with Claude Desktop, Cursor, VS Code (Copilot agent mode), Cline, and any other MCP-compatible client. Each detail page lists the clients the project explicitly supports.
