Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Google Ads account to Claude via Composio Connect, enabling it to create a new customer list for holiday campaigns, get campaign details by campaign ID, list all current customer lists in your account, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

You can also connect Claude to multiple Google Ads accounts with Composio.

3. Connect your Google Ads account

Back in Claude, ask it to connect to Google Ads or give it any Google Ads-related task.

For example, ask Claude to:

  • "Create a new customer list for holiday campaigns"
  • "Get campaign details by campaign ID"
  • "List all current customer lists in your account"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Google Ads account is ready to use.

What is the Google Ads Claude Connector, and what's possible with it?

The Google Ads MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Ads account. It provides structured and secure access to your advertising data, so your agent can perform actions like creating customer lists, retrieving campaign details, and managing audience segments on your behalf.

  • Automated customer list creation: Instantly have your agent create new customer lists for targeted marketing campaigns, streamlining your segmentation workflows.
  • Campaign insights by ID or name: Let your agent fetch detailed information for any ad campaign using its ID or name, making reporting and optimization a breeze.
  • Customer list management: Ask your agent to retrieve and review all your existing customer lists, so you always know who you're targeting.
  • Add or remove contacts from lists: Seamlessly update audience membership by having your agent add or remove contacts from specified customer lists for more dynamic targeting.

Troubleshooting

1. Why does Claude not use the Composio connector for Google Ads?

The connector can show as connected, but Claude must use it in each Google Ads conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Google Ads again.

2. Why does Claude show an MCP server error before Google Ads connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Google Ads.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Google Ads.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Google Ads authorization link not work?

The Composio connector is one server. Your Google Ads account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Google Ads connection.
  • Composio creates a fresh Google Ads authorization link.
  • Open that link in your browser and finish the Google Ads sign-in.

4. Why do Google Ads actions fail after they worked before?

The Google Ads connection can expire or lose permission.

  • Ask Claude to inspect the Google Ads connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Google Ads account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Google Ads.
  • If the action still fails with a permission error, check that the connected account has that permission in Google Ads itself.

5. How do I switch to a different Google Ads account?

Claude can manage the Google Ads connection for you.

  • Ask Claude to disconnect or delete the current Google Ads account.
  • Ask Claude to connect Google Ads again.
  • Open the new Composio authorization link for Google Ads.
  • Sign in with the other Google Ads account in the browser.
  • After the account connects, ask Claude to retry the Google Ads task.

6. Why is my Google Ads connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Google Ads connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Google Ads tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Google Ads.

FAQ

Frequently asked questions

With a standalone Google Ads MCP server, the agents and LLMs can only access a fixed set of Google Ads tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Google Ads and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Google Ads tools.

Yes, absolutely. You can configure which Google Ads scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Google Ads data and credentials are handled as safely as possible.
