Frequently Asked Questions

What are MCP servers?

MCP (Model Context Protocol) servers are lightweight programs that expose tools, resources, and prompts to AI clients like Cursor, Claude Desktop, and VS Code. They let AI models interact with external systems such as databases, APIs, browsers, and developer tools through a standardized protocol created by Anthropic.

How do I install MCP servers?

Most MCP servers can be installed with a single command or config change. On MCP.Directory, click the Install button on any server page to get one-click installation for Cursor, Claude Desktop, VS Code, Claude Code, and other supported clients. You can also install manually via npm, pip, or Docker depending on the server.

Are MCP servers free?

The vast majority of MCP servers are free and open source. Most are published under permissive licenses like MIT or Apache 2.0. Some servers connect to paid third-party services (like cloud databases or SaaS tools), but the MCP server software itself is typically free to use.

Which AI clients support MCP servers?

MCP is supported by a growing number of AI tools including Cursor IDE, Claude Desktop, VS Code (via GitHub Copilot), Claude Code, Windsurf, Codex, Gemini CLI, ChatGPT, and Zed. Any tool that implements the MCP protocol can connect to MCP servers.

How do I choose the best MCP server for my needs?

Consider what you need the AI to interact with (browsers, databases, APIs, etc.), then compare servers in that category by GitHub stars, weekly downloads, and community adoption. Check whether the server supports your AI client, and read the documentation to ensure it covers your use case. MCP.Directory lets you filter and compare servers to find the best match.

Can I use multiple MCP servers at the same time?

Yes. Most AI clients support connecting to multiple MCP servers simultaneously. For example, you can run a database server, a browser automation server, and a file system server all at once, giving your AI access to all their tools in a single session.
