Sync GTM MCP Server

The Sync GTM Model Context Protocol (MCP) server enables AI assistants like Claude Code, Cursor, VS Code Copilot, and other MCP-compatible clients to interact directly with your Sync GTM workspace.

With the MCP server, AI agents can go beyond code generation and perform advanced GTM operations in your Sync GTM workspace — manage tables, run actions, query data, and automate workflows with full awareness of your workspace context.

Prerequisites

• A Sync GTM account with an active API token
• An MCP-compatible client such as Claude Code , Cursor , VS Code , or any other client that supports the MCP specification

Getting Your API Token

1. Log in to your Sync GTM dashboard at app.syncgtm.com 
2. Navigate to Settings and find your API token
3. Copy the token — it starts with rxk_

Keep your API token secure. Never commit it to version control or share it publicly.

Installation

Claude Code

Run the following command in your terminal to add the Sync GTM MCP server:

claude mcp add --transport http syncgtm https://api.syncgtm.com/mcp --header "Authorization: Bearer rxk_YOUR_API_TOKEN"

Replace rxk_YOUR_API_TOKEN with your actual Sync GTM API token.

The next time you start Claude Code, it will have access to your Sync GTM workspace.

Cursor

1. Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run View: Open MCP Settings.
2. Select + New MCP Server in the settings pane. This will open your mcp.json file.
3. Add the following configuration:

{
  "mcpServers": {
    "syncgtm": {
      "type": "http",
      "url": "https://api.syncgtm.com/mcp",
      "headers": {
        "Authorization": "Bearer rxk_YOUR_API_TOKEN"
      }
    }
  }
}

Replace rxk_YOUR_API_TOKEN with your actual API token. Once saved, Cursor will detect the new server and connect automatically.

VS Code

1. Open Visual Studio Code.
2. In the Command Palette (Cmd+Shift+P / Ctrl+Shift+P), run: MCP: Open User Configuration.
3. Update the mcp.json file with the following configuration and save:

{
  "servers": {
    "syncgtm": {
      "type": "http",
      "url": "https://api.syncgtm.com/mcp",
      "headers": {
        "Authorization": "Bearer rxk_YOUR_API_TOKEN"
      }
    }
  }
}

Windsurf

Add the following to your Windsurf MCP configuration file:

{
  "mcpServers": {
    "syncgtm": {
      "type": "http",
      "url": "https://api.syncgtm.com/mcp",
      "headers": {
        "Authorization": "Bearer rxk_YOUR_API_TOKEN"
      }
    }
  }
}

Usage

Once configured, you can use natural language to interact with your Sync GTM workspace. Example prompts:

• “Find the work email for John Smith at Acme Corp”
• “Enrich this company domain and tell me their tech stack”
• “Check if this company has raised funding recently”
• “Find employees at this company in sales roles”
• “Get the LinkedIn profile for this prospect and pull their recent posts”
• “Check if this phone number is on WhatsApp”

Troubleshooting

Authentication Errors (401 Unauthorized)

• Verify your API token is correct and starts with rxk_
• Make sure the key has not been revoked or expired
• Check that the Authorization header is formatted as Bearer rxk_YOUR_API_TOKEN (with a space after Bearer)

Connection Issues

• Ensure your network allows outbound HTTPS requests to api.syncgtm.com
• If using the npx method, make sure Node.js (v18+) and npm are installed
• Try restarting your MCP client after updating the configuration

Tools Not Appearing

• Restart your MCP client (Claude Code, Cursor, VS Code, etc.)
• Verify the MCP server is listed and connected in your client’s MCP settings
• Check that your API token has the required permissions for your workspace

Security

• Your API token is used only to authenticate requests to the Sync GTM API
• All communication uses HTTPS encryption
• Never share your API token or commit it to version control
• You can rotate your API token at any time from the Sync GTM dashboard
