Smart Conversion Debugging MCP Server

An MCP server that helps debug conversion tracking issues across GoHighLevel, Meta CAPI, webhooks, and GTM.

Quick Start

# Install dependencies
npm install

# Test tools locally
node test.js

# Run interactive CLI agent
node agent.js

# Start MCP server (for AI client connections)
node index.js

Available Tools

Tool	Description
`getWebhookEvents`	Returns stored webhook events
`getGHLContacts`	Fetch contacts from GoHighLevel
`getMetaEvents`	Returns Meta CAPI tracked events
`getGTMEvents`	Returns frontend GTM events
`getSystemLogs`	Returns error logs
`debugConversion`	Full analysis with issues + fixes

Connecting to MCP Clients

1. Claude Desktop

Edit your Claude Desktop config file:

Windows: %APPDATA%\Claude\claude_desktop_config.json

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "conversion-debugger": {
      "command": "node",
      "args": ["D:/first mcp server/index.js"],
      "env": {
        "USE_MOCK_DATA": "true"
      }
    }
  }
}

Restart Claude Desktop after saving. You'll see the tools available in the chat.

2. VS Code with GitHub Copilot

Add to your VS Code settings.json or workspace settings:

{
  "github.copilot.chat.mcpServers": {
    "conversion-debugger": {
      "command": "node",
      "args": ["D:/first mcp server/index.js"],
      "env": {
        "USE_MOCK_DATA": "true"
      }
    }
  }
}

Or create .vscode/mcp.json in your workspace:

{
  "servers": {
    "conversion-debugger": {
      "command": "node",
      "args": ["${workspaceFolder}/index.js"],
      "env": {
        "USE_MOCK_DATA": "true"
      }
    }
  }
}

3. Cursor IDE

Add to Cursor settings (~/.cursor/mcp.json or project .cursor/mcp.json):

{
  "mcpServers": {
    "conversion-debugger": {
      "command": "node",
      "args": ["D:/first mcp server/index.js"],
      "env": {
        "USE_MOCK_DATA": "true"
      }
    }
  }
}

4. Continue.dev

Add to your Continue config (~/.continue/config.json):

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "node",
          "args": ["D:/first mcp server/index.js"]
        }
      }
    ]
  }
}

5. Custom MCP Client (Node.js)

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";
import { spawn } from "child_process";

const transport = new StdioClientTransport({
  command: "node",
  args: ["D:/first mcp server/index.js"],
});

const client = new Client({ name: "my-client", version: "1.0.0" });
await client.connect(transport);

// List available tools
const tools = await client.listTools();
console.log(tools);

// Call a tool
const result = await client.callTool({
  name: "debugConversion",
  arguments: {},
});
console.log(result);

await client.close();

Environment Variables

Copy .env.example to .env and configure:

# Use mock data (set to false for live API calls)
USE_MOCK_DATA=true

# GoHighLevel
GHL_API_KEY=your_api_key
GHL_LOCATION_ID=your_location_id

# Meta CAPI
META_ACCESS_TOKEN=your_access_token
META_PIXEL_ID=your_pixel_id

Example AI Prompts

Once connected to an MCP client, try these prompts:

"Debug my conversion tracking"
- The AI will call debugConversion and explain the issues
"Show me all GHL contacts from today"
- Calls getGHLContacts with date filters
"Compare webhook events with Meta events"
- Calls multiple tools and cross-references data
"Why are some conversions not reaching Meta?"
- Full debugging workflow with root cause analysis
