mcp-hosts-installer

Install Model Context Protocol (MCP) servers from npm, PyPI, or a local path — directly from Claude Code, Cursor, VS Code, or Claude Desktop.

One setup: add this server once, then ask the model to install other MCP packages for you.

What you get

• Tools exposed to the host: `install_repo_mcp_server` (npm/PyPI package name) and `install_local_mcp_server` (folder path), with optional `args`, `env`, and target `host` (`claude-code` \| `cursor` \| `vscode` \| `claude`).
• Default host: when `host` is omitted, the tool picks a client that already has a config file in the usual folder (Cursor first, then VS Code, then Claude Code, then Claude Desktop); if none exist, it targets Cursor.
• Prerequisites: Node.js with `npx`; for Python-based servers from PyPI, `uv` is used.

Install this MCP server in your host

Claude Code ⭐

The fastest way — one CLI command:

claude mcp add mcp-hosts-installer npx -- -y mcp-hosts-installer

Or manually in `~/.claude/settings.json` (created automatically if it doesn't exist):

{
  "mcpServers": {
    "mcp-hosts-installer": {
      "command": "npx",
      "args": ["-y", "mcp-hosts-installer"]
    }
  }
}

Then ask Claude Code:

> Install the MCP server @modelcontextprotocol/server-filesystem for claude-code

Cursor

`mcp.json` — macOS: `~/.cursor`, Windows: `%USERPROFILE%\.cursor`.

{
  "mcpServers": {
    "mcp-hosts-installer": {
      "command": "npx",
      "args": ["-y", "mcp-hosts-installer"]
    }
  }
}

VS Code

User-level `mcp.json`: macOS `~/Library/Application Support/Code/User/mcp.json`, Windows `%APPDATA%\Code\User\mcp.json`, Linux `~/.config/Code/User/mcp.json`. In VS Code: command MCP: Open User Configuration.

{
  "mcpServers": {
    "mcp-hosts-installer": {
      "command": "npx",
      "args": ["-y", "mcp-hosts-installer"]
    }
  }
}

Claude Desktop

`claude_desktop_config.json` — macOS: `~/Library/Application Support/Claude`, Windows: `%APPDATA%\Claude`.

{
  "mcpServers": {
    "mcp-hosts-installer": {
      "command": "npx",
      "args": ["-y", "mcp-hosts-installer"]
    }
  }
}

If you don't pass `host`, use the inference above or set `host` to `"claude-code"`, `"claude"`, `"cursor"`, or `"vscode"` explicitly.

Example prompts

> Install the MCP server named mcp-server-fetch

> Please install the MCP server at /Users/NAME/code/mcp-youtube, I'm too lazy to do it myself.

> Install the MCP server @modelcontextprotocol/server-github for claude-code. Set the environment variable GITHUB_PERSONAL_ACCESS_TOKEN to '1234567890'
