La Growth Machine MCP Server

A Model Context Protocol (MCP) server that wraps the full La Growth Machine API, giving Claude (and any MCP-compatible client) direct access to your LGM workspace.

Features

27 tools covering every LGM API endpoint:

Prerequisites

• Node.js >= 18
• A La Growth Machine account with API access (Business plan, currently at 100 EUR/month)
• Your LGM API key from Settings > API

Installation

git clone https://github.com/GigRadar/lgm-mcp-server.git
cd lgm-mcp-server
npm install
npm run build

Claude Desktop Setup

Add the following to your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "lgm": {
      "command": "node",
      "args": ["/absolute/path/to/lgm-mcp-server/dist/index.js"],
      "env": {
        "LGM_API_KEY": "your-api-key-here"
      }
    }
  }
}

Replace /absolute/path/to/lgm-mcp-server with the actual path where you cloned the repo, and your-api-key-here with your LGM API key.

Then restart Claude Desktop to pick up the new server.

Claude Code Setup

claude mcp add lgm -- node /absolute/path/to/lgm-mcp-server/dist/index.js

Set the environment variable before launching:

export LGM_API_KEY=your-api-key-here

Usage Examples

Once connected, you can ask Claude things like:

• "List all my LGM campaigns and their stats"
• "Search for a lead by email [email protected]"
• "Create a new lead in audience X with these details..."
• "Send a LinkedIn message to https://linkedin.com/in/someone saying..."
• "Show me the activity logs for lead ID abc123"
• "Set up a webhook to receive inbox events at https://my-server.com/webhook"

Development

npm run build        # Compile TypeScript
npm run test         # Run unit tests
npm run test:e2e     # Run E2E tests (requires LGM_API_KEY)
npm run test:all     # Run all tests

Known Limitations

• POST /inbox/email can only reply to existing email threads — it cannot initiate new email conversations. You must provide a replyToMessageId (from get_conversation_messages) or set replyInLastThread: true. Use either leadId or leadEmail, not both.
