@channel47/google-ads-mcp

MCP server for Google Ads API access via GAQL (Google Ads Query Language). Built by a practitioner managing 25+ ad accounts daily — not a demo.

Part of channel47, the open-source ecosystem of profession plugins for Claude Code. Get the newsletter for weekly skill breakdowns from production use.

What It Does

• List accounts accessible under your MCC or individual credentials
• Query anything with raw GAQL — campaigns, ad groups, keywords, search terms, assets, any resource
• Mutate entities — campaigns, ad groups, ads, keywords, budgets, assets with dry-run safety
• Resources and prompts — bundled GAQL reference docs and operation templates

        "update": {
          "resourceName": "customers/1234567890/campaigns/123",
          "status": "PAUSED"
        },
        "updateMask": "status"
      }
    }
  ],
  "dry_run": false
}

Working with Responsive Search Ads (RSAs)

RSAs have two different resource types with different mutability:

Update RSA headlines/descriptions (use entity: 'ad'):

{
  "operations": [{
    "entity": "ad",
    "operation": "update",
    "resource": {
      "resource_name": "customers/1234567890/ads/9876543210",
      "responsive_search_ad": {
        "headlines": [
          {"text": "New Headline 1"},
          {"text": "New Headline 2"},
          {"text": "New Headline 3"}
        ],
        "descriptions": [
          {"text": "New Description 1"},
          {"text": "New Description 2"}
        ]
      },
      "final_urls": ["https://example.com"]
    }
  }],
  "dry_run": false
}

Change RSA status (use entity: 'ad_group_ad'):

{
  "operations": [{
    "entity": "ad_group_ad",
    "operation": "update",
    "resource": {
      "resource_name": "customers/1234567890/adGroupAds/111222333~9876543210",
      "status": "PAUSED"
    }
  }],
  "dry_run": false
}

Creating Image Assets with File Paths

When creating image assets, you can provide a local file path instead of base64 data:

{
  "operations": [{
    "entity": "asset",
    "operation": "create",
    "resource": {
      "name": "My Image Asset",
      "image_file_path": "/path/to/image.png"
    }
  }]
}

The server will automatically read the file and convert it to the required base64 format.

Creating Campaigns

Campaign creation requires specific fields since Google Ads API v19.2 (September 2025):

Complete campaign creation example:

{
  "operations": [
    // 1. Create budget first (with temp ID for atomic creation)
    {
      "entity": "campaign_budget",
      "operation": "create",
      "resource": {
        "resource_name": "customers/1234567890/campaignBudgets/-1",
        "name": "My Budget",
        "amount_micros": 10000000,
        "delivery_method": "STANDARD"
      }
    },
    // 2. Create campaign referencing the budget
    {
      "entity": "campaign",
      "operation": "create",
      "resource": {
        "name": "My Search Campaign",
        "advertising_channel_type": "SEARCH",
        "status": "PAUSED",
        "campaign_budget": "customers/1234567890/campaignBudgets/-1",
        "manual_cpc": { "enhanced_cpc_enabled": false },
        "network_settings": {
          "target_google_search": true,
          "target_search_network": true
        }
      }
    }
  ],
  "dry_run": false
}
