Think of this as the App Store for MCP servers. It connects to the official MCP Registry API at registry.run.mcp.com.ai, letting you publish and discover servers across the ecosystem. You can browse available servers, search by capability, and pull down metadata to integrate servers into your MCP client. Publishing supports GitHub OAuth, GitHub Actions OIDC, and domain verification via DNS or HTTP challenges. The registry validates namespace ownership automatically, so publishing to io.github.username requires proving you control that GitHub account or domain. Reach for this when you're building an MCP client that needs server discovery, or when you want to make your own server findable by others in the community.
