š Super Easy Installation
ā” 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.
# š„ Using npx (no installation required)
npx leadmagic-mcp-server install
⨠The installer will:
- ā Validate your API key in real-time and show your remaining credits.
- ā Automatically detect and configure your preferred AI tool (Claude, Cursor, VS Code, etc.).
- ā
Create all necessary config files and a local
.envfor development. - ā Provide usage examples and helpful links.
š± 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
š Get Your API Key
- š Visit LeadMagic Dashboard
- š Sign up for free (if needed)
- š Generate your API key
- š Paste it into the interactive installer when prompted.
ā” npx Usage (Zero Installation)
You can use the server without installing, which is great for quick tests or containerized environments:
# š Run directly with your API key
LEADMAGIC_API_KEY=your-key npx leadmagic-mcp-server
# š Run the interactive installer
npx leadmagic-mcp-server install
# ā Check available commands
npx leadmagic-mcp-server --help
