The mcp-installer server enables users to programmatically install other MCP servers through Claude by providing tools that handle npm and PyPI package installation and configuration. It eliminates manual setup steps by allowing Claude to install servers, configure arguments, and set environment variables directly within the Claude Desktop configuration. The server requires `npx` for Node.js packages and `uv` for Python packages to function.
This server is a server that installs other MCP servers for you. Install it, and you can ask Claude to install MCP servers hosted in npm or PyPi for you. Requires npx and uv to be installed for node and Python servers respectively.
Put this into your claude_desktop_config.json (either at ~/Library/Application Support/Claude on macOS or C:\Users\NAME\AppData\Roaming\Claude on Windows):
"mcpServers": {
"mcp-installer": {
"command": "npx",
"args": [
"@anaisbetts/mcp-installer"
]
}
}
