Smithery CLI

Package manager for MCP servers and agent skills

open sourceupdated Apr 21, 2026

Smithery is a CLI tool and registry for discovering, installing, and managing MCP servers and agent skills. It lets developers search thousands of available servers, install them with one command, inspect available tools, and connect their AI coding agents to external capabilities through the Model Context Protocol standard.

Smithery addresses a critical gap in the MCP ecosystem: discoverability and management. As the number of MCP servers has exploded past 5,500+ in community registries, finding the right server for a specific task and configuring it correctly has become increasingly difficult. Smithery provides a curated registry with search, categorization, and usage statistics, plus a CLI that handles installation, configuration, and connection management for MCP servers across different AI client environments.

The CLI supports key operations that developers need in their daily agentic workflows: searching the registry for servers by functionality, installing servers with automatic dependency resolution, listing installed servers and their available tools, and calling individual tools for testing. This makes Smithery function as the 'npm for MCP servers' — a package manager that brings order to a rapidly growing ecosystem of agent capabilities.

With 620+ GitHub stars and growing adoption as the MCP ecosystem matures, Smithery fills an essential infrastructure role. It integrates with Claude Desktop, Cursor, and other MCP-compatible clients, providing a centralized way to manage the expanding set of tools and data sources that AI agents need to access. The registry includes servers for databases, cloud services, developer platforms, browser automation, and specialized domain tools.
