google-ads-transparency-mcp

An MCP server that lets AI assistants look up any advertiser's Google ads. Search by domain or company name, retrieve ad creatives, and decode text ad content — all from Google's Ads Transparency Center.

No API key. No paid service. No browser required.

Google has no official API for their Ads Transparency Center. The only open-source option was an abandoned Python package (last commit July 2023, broken domain search, crashed on image ads). Paid alternatives start at $75/mo. This project fixes the scraper and wraps it as an MCP server so any AI assistant can query Google's ad database directly.

| Tool | Description | |------|-------------| | search_advertiser_by_domain | Find an advertiser by website domain (e.g. nike.com) | | search_advertisers | Search advertisers by keyword or company name | | get_ads | Get ads for an advertiser with decoded content | | get_ad_detail | Get full details for a specific ad creative |
