Installer MCP Server

Overview

MCP Installer is a meta-server that allows you to install other MCP servers directly through Claude. This eliminates the need to manually configure each MCP server in your configuration file, as you can simply ask Claude to install them for you on demand.

Installation

To install MCP Installer, add the following configuration to your claude_desktop_config.json file:

• On macOS: Located at ~/Library/Application Support/Claude
• On Windows: Located at C:\Users\USERNAME\AppData\Roaming\Claude

"mcpServers": {
  "mcp-installer": {
    "command": "npx",
    "args": [
      "@anaisbetts/mcp-installer"
    ]
  }
}

Prerequisites

MCP Installer requires the following tools to be installed on your system:

• npx for installing Node.js-based MCP servers
• uv for installing Python-based MCP servers

Make sure these tools are available in your system's PATH.

Usage

Once installed, you can ask Claude to install other MCP servers using natural language. Here are some example prompts:

Installing an npm package

Hey Claude, install the MCP server named mcp-server-fetch

Installing with custom arguments

Hey Claude, install the @modelcontextprotocol/server-filesystem package as an MCP server. Use ['/Users/username/Desktop'] for the arguments

Installing from a local directory

Hi Claude, please install the MCP server at /Users/username/code/mcp-youtube

Setting environment variables

Install the server @modelcontextprotocol/server-github. Set the environment variable GITHUB_PERSONAL_ACCESS_TOKEN to '1234567890'

The MCP Installer will parse your request, install the specified server, and configure it appropriately based on your instructions.
