Smithery is an MCP server registry and hosting platform that lets developers discover, publish, and connect to Model Context Protocol servers from any AI agent. The platform combines a public registry of thousands of community MCP servers with a managed gateway that handles OAuth, credential storage, session state, protocol compliance, and webhook triggers — so agents can call tools across servers via a single stateless Connect API. Smithery also distributes a CLI, a TypeScript API client, a local runner, a Skills Registry, deep-linking integrations for popular MCP clients (Claude Desktop, Cursor, Continue), and uplink support for exposing local servers as hosted connections.
