This MCP server acts as a centralized installer that can fetch and install other MCP servers for you. It enables Claude to install MCP servers hosted either on npm (Node-based) or PyPi (Python-based) on demand. The server requires npx for Node-based installations and uv for Python-based installations to be present on the host system. Users configure it by adding an mcp-installer entry in claude_desktop_config.json, specifying the command (npx) and the arguments to point to the MCP installer package (e.g., @anaisbetts/mcp-installer). It supports installing MCP servers by name (e.g., mcp-server-fetch) or by providing a filesystem path to a local server, and even allows authentication tokens via environment variables (e.g., GITHUB_PERSONAL_ACCESS_TOKEN). The README also provides example prompts showing how Claude can install servers by package name, path, or custom GitHub-based installations. This server thus enables a streamlined, prompt-driven workflow for composing and deploying multiple MCP servers from a single interface.
