About Smithery

Smithery is a centralized platform and registry that lets developers publish, discover, install, and host Model Context Protocol (MCP) servers to extend the capabilities of language-model agents. It provides standardized MCP interfaces, an SDK and scaffolding for building MCP servers, a CLI for installing and running servers, and hosting/gateway functionality so agents can access external services through a unified gateway. By combining a searchable registry, developer tooling, and one-line installers for multiple clients, Smithery accelerates distribution and adoption of interoperable agent extensions and simplifies integration across agent platforms.

Key Features

Centralized Registry: A searchable registry (app-store) of MCP servers where developers can discover published servers, read metadata, and inspect available tools and endpoints for agent integration.
Standardized MCP Interfaces: Enforces and exposes standardized Model Context Protocol interfaces and configuration schemas so agents can integrate tools consistently across different servers and clients.
Hosting and Gateway: Provides hosting and a unified gateway so agents can access external MCP services without complex per-client setup, improving availability and cross-client compatibility.
CLI Installer and Management: A command-line tool to search, install, run, inspect, develop, build, and run MCP servers locally or in dev mode (commands include search, inspect, run, dev, build, playground, install), simplifying lifecycle management.
SDK and Scaffolding: Developer SDK and server templates (FastMCP servers and scaffolds) to bootstrap new MCP servers with session configuration support and recommended patterns for production deployment.
Toolbox Dynamic Routing: A toolbox-style MCP that dynamically routes requests to registry MCPs and prompts users to configure tools when needed, enabling flexible runtime tool selection for agents.
One-line Client Installers: Provides one-line installers and client integration helpers that reduce manual conversion and configuration across multiple agent clients, easing adoption in projects like chat clients.
