MCP is an open protocol that allows AI assistants like Claude to connect to external tools and data sources. It enables Claude to interact with databases, APIs, file systems, and other services securely. Think of it as giving your AI the ability to actually do things, not just talk about them.
Yes, Relay is completely free and open source. There are no premium tiers, no subscriptions, and no hidden costs. You can download it, use it, and even contribute to its development on GitHub.
No. Relay stores all data locally on your machine. There's no cloud sync, no telemetry, no analytics. Your API keys and server configurations never leave your computer. We built Relay with privacy as a core principle.
Relay supports 12+ AI clients including Claude Desktop, Cursor, VS Code (with GitHub Copilot MCP), Continue, Claude Code, Windsurf, Cline, Zed, 5ire, Void, Glama, and Msty. We're constantly adding support for more tools.
Not at all. Relay was designed for everyone—developers and non-developers alike. You just browse the catalog, click to add servers, fill in your API keys through simple forms, and click export. No command line, no JSON editing.
Yes! While Relay comes with 53+ pre-configured servers, you can also add any custom MCP server manually. Just provide the command, arguments, and environment variables—Relay handles the rest.
Each server has different requirements. When you add a server in Relay, we provide hints and links to help you get the necessary API keys. For example, GitHub requires a personal access token, which you can generate in your GitHub settings.
No, Relay is an independent open-source project. While it works great with Claude Desktop and Claude Code (both by Anthropic), Relay itself is not affiliated with or endorsed by Anthropic.
