🎯 Access all 19 LeadMagic API endpoints through the Model Context Protocol for seamless integration with Claude, Cursor, Windsurf, Continue.dev, and other MCP-compatible AI tools.

πŸš€ Super Easy Installation

⚑ Option 1: Interactive Installer (Recommended)

The easiest way to get started - works on macOS, Windows, and Linux. Our new interactive installer, built with React and Ink, makes setup a breeze.

# πŸ”₯ Using npx (no installation required)
npx leadmagic-mcp-server install

✨ The installer will:

  • βœ… Validate your API key in real-time and show your remaining credits.
  • βœ… Automatically detect and configure your preferred AI tool (Claude, Cursor, VS Code, etc.).
  • βœ… Create all necessary config files and a local .env for development.
  • βœ… Provide usage examples and helpful links.

πŸ“± Option 2: Quick Manual Setup

If you prefer manual setup or are using a client like Aider, you can add the server configuration directly to your client's settings file. The interactive installer provides copy-pasteable snippets for this.

Run the installer and choose the "Other (Manual Setup)" option:

npx leadmagic-mcp-server install

πŸ”‘ Get Your API Key

  1. 🌐 Visit LeadMagic Dashboard
  2. πŸ“ Sign up for free (if needed)
  3. πŸ” Generate your API key
  4. πŸ“‹ Paste it into the interactive installer when prompted.

⚑ npx Usage (Zero Installation)

You can use the server without installing, which is great for quick tests or containerized environments:

# πŸš€ Run directly with your API key
LEADMAGIC_API_KEY=your-key npx leadmagic-mcp-server

# πŸ“‹ Run the interactive installer
npx leadmagic-mcp-server install

# ❓ Check available commands
npx leadmagic-mcp-server --help
