Mcp Installer

What is Mcp Installer about?

Mcp Installer provides a unified MCP server that can fetch and set up other MCP servers from npm or PyPi, allowing Claude to manage server installation on demand.

How to use Mcp Installer?

1. Ensure npx (Node) and uv (Python) are installed on your machine.
2. Add the following entry to your claude_desktop_config.json (macOS or Windows path as described):

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

3. In Claude, issue natural‑language prompts such as:

• “Hey Claude, install the MCP server named mcp-server-fetch.”
• “Install the @modelcontextprotocol/server-github package and set GITHUB_PERSONAL_ACCESS_TOKEN to '1234567890'.” Claude will invoke the installer to pull the requested server.

Key Features of Mcp Installer

• Single entry point for installing any MCP server.
• Supports npm (Node) and PyPi (Python) packages.
• Uses npx for Node installations (no global install needed).
• Leverages uv for fast Python package handling.

FAQ from the Mcp Installer

Q: Do I need to install the MCP server manually? A: No. Once Mcp Installer is added to the Claude config, you can request installations via chat.

Q: What if I want to install a server from a local path? A: Include the absolute path in your prompt (e.g., “install the MCP server at /Users/.../mcp-youtube”).

Q: Are environment variables supported? A: Yes. Specify them in the prompt; Mcp Installer will set them before launching the target server.

Q: Can I install both Node and Python servers with the same command? A: The installer detects the package type and uses npx for npm packages or uv for PyPi packages automatically.

Q: What happens if the required package manager is missing? A: Claude will respond with an error indicating that npx or uv needs to be installed.
