# MCP Magnet [日本語版はこちら](README_ja.md) MCP Magnet is a local application that makes it easy to install and manage Model Context Protocol (MCP) servers. <p align="center"> <a href="https://github.com/acomagu/mcp-magnet/releases/latest"> <img src="logo.png" alt="MCP Magnet logo" width="200" /> <br /> <i>Download Now!</i> </a> </p> ## What is MCP Magnet? MCP Magnet lets you install, configure, and manage an MCP server without ever editing a JSON file by hand. Its key features include: - **One-click install** – Quickly install an MCP server via a deep link - **Custom manifests** – Anyone can create and share links — **[Link Generator](https://playground.mcpmagnet.app)** - **Permission overview** – Check what permissions a local MCP server requires (currently Deno only) - **Runtime auto-install** – Detects and, with your confirmation, installs the runtime needed to run the MCP server (currently Deno only) - **Fully local operation** – Works entirely on your machine with no calls to proprietary servers[^1] [^1]: When you follow a magnet link you may be routed through the gateway page (open.mcpmagnet.app). This happens for two reasons: (1) GitHub and the VS Code Marketplace README views don’t support custom-scheme links, and (2) users who don’t have MCP Magnet installed need installation guidance. The gateway page never collects any user data. ### Features in development - Automatic download of MCP server binaries - Management UI for already-installed MCP servers - Runtime Modifier – Choose your favourite container/runner for the MCP server (Docker / Deno / sandbox-exec, etc.) - Cross-device sync – Sync MCP server settings across devices (e.g. via Google Drive) - Update notifications when a new MCP server version is released - Support for additional runtimes / container technologies ### Concept - Make it effortless for users to install an MCP server - Make distribution of MCP servers easy for developers - Surface security and privacy information - No lock-in – Stabilise the manifest spec so other installers can implement it too ## Try-it-out links After [installing MCP Magnet](https://github.com/acomagu/mcp-magnet/releases/latest), click any of the links below to open an installation dialog for an MCP server: -
