Why connect GTM to Google Antigravity?

Antigravity's agents plan and run tasks across your editor, terminal and browser, and can hand you the result to review. Connected through Lemonado, it reads your GTM tags, triggers, variables and versions, so it can find what a new version changed with today's numbers.

  • All your GTM data

    Accounts, containers and workspaces, ready to ask about.

  • Always today's numbers

    Triggers and the conditions behind them, synced from GTM automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Why did conversions drop?" use GTM and GA4, Google Ads at once.

How to connect GTM to Google Antigravity

Before you start

  • A Google Tag Manager account you can sign in to
  • Antigravity installed
  • A Lemonado account (the free trial works)
  1. 1

    Connect Google Tag Manager in Lemonado

    In Lemonado, open Connectors, find Google Tag Manager and sign in. Sign in with a Google account that has at least Read access to the GTM containers you want to audit. Pick the web container your site uses.

  2. 2

    Turn on external access

    In the company's settings, open External tools, turn the connection on, choose which sources it can reach and copy the server URL.

    text
    https://mcp.lemonado.io/mcp
  3. 3

    Open the raw MCP config

    In the agent panel, open … → MCP Servers → Manage MCP Servers → View raw config. That's ~/.gemini/config/mcp_config.json globally, or .agents/mcp_config.json for a workspace.

  4. 4

    Add Lemonado

    Merge this in. Remote servers use serverUrl.

    json
    {
  "mcpServers": {
    "lemonado": {
      "serverUrl": "https://mcp.lemonado.io/mcp"
    }
  }
}
  5. 5

    Authenticate

    Refresh the servers, then choose Authenticate beside Lemonado under Settings → Customizations. If you're shown a code, paste it back. In the Antigravity CLI, use /mcp.

  6. 6

    Ask Google Antigravity about GTM

    Try "Build a small internal page that charts last quarter's GTM numbers by week, then open it in the browser to check it." Or ask: "Document the tracking" or "What breaks if I rename this?"

What can Google Antigravity do with GTM?

Antigravity's agents read your GTM data while they build: a page that charts the numbers, a check on your tracking, a report in the repo.

AGoogle Antigravity

- Transport: Streamable HTTP
- Auth: OAuth; the user signs in to Lemonado in the browser. No API keys.
- In Lemonado: connect the GTM account and container. Sign in with a Google account that has at least Read access to the GTM containers you want to audit. Pick the web container your site uses.

If you are Google Antigravity, run the setup yourself:

Add the Lemonado MCP server to my global MCP config (~/.gemini/config/mcp_config.json). Merge in: {"mcpServers":{"lemonado":{"serverUrl":"https://mcp.lemonado.io/mcp"}}}
Then tell me to refresh MCP servers and choose Authenticate next to Lemonado. Once I've signed in, list the Google Tag Manager accounts Lemonado can reach.

FAQ

Frequently Asked Questions

Yes, through Lemonado. Connect your GTM account and container in Lemonado, add Lemonado in Antigravity's MCP config, and Antigravity can find what a new version changed with your live data.

No, Google doesn't run one. Community servers exist, and most can edit and publish your container, so check what you grant them. Lemonado gives Antigravity read-only access to your containers, next to GA4 and your ad platforms.

Open Manage MCP Servers, refresh, and choose Authenticate next to Lemonado if it isn't signed in. In Lemonado, check that Google Tag Manager is connected and External tools is on for the company. If a container is missing, your Google user needs access to it in Tag Manager > Admin > User Management. Account access alone isn't always enough.

Yes, if both are connected in Lemonado. One connection reaches every source you allow, so you can ask things like "Google Ads conversions fell on Oct 18. Check which GTM version was published that week and what it changed."

MCP is included in Lemonado's paid plans and in the free trial, so you can try it before you pay.
