Smithery

Smithery is a platform for finding, connecting to, and publishing MCP (Model Context Protocol) servers and Agent Skills that extend AI agents with thousands of tools. It provides a single gateway for agents to securely access external services—handling OAuth, credentials, and persistent sessions automatically. Developers can publish their own MCP servers to Smithery for distribution, observability, and built-in authentication without implementing auth flows themselves. The platform hosts over 4,700 MCP servers and 125,000+ Skills spanning web search, productivity tools, databases, communication platforms, and more.

• MCP Server Registry — Browse and search thousands of MCP servers including Exa, GitHub, Notion, Slack, Supabase, and more from a central directory.
• Agent Skills — Pre-built workflows and behavioral extensions that customize agent capabilities, publishable and installable by any user.
• Managed OAuth — Built-in OAuth handling so agents can authenticate with third-party services without custom auth implementation.
• Persistent Connections — Maintain stateful, long-running connections between agents and MCP servers across sessions.
• CLI Tool — Use npx @smithery/cli@latest setup to quickly wire up MCP servers to your agent from the terminal.
• TypeScript SDK — Programmatically connect agents to MCP tools via the Smithery SDK for custom integrations.
• Publish & Distribute — Publish MCP servers once and make them installable from any AI client, with usage observability built in.
• Observability — Track how your published tools are called, monitor usage metrics, and improve the agent experience.
• LLM-Friendly Docs — Documentation available in Markdown and via MCP server at smithery.ai/docs/mcp for direct agent consumption.
