Google Ads Transparency tracker: an MCP database you can query from Claude Code or Cursor
Whether the products on our watchlist buy Google ads (Search, YouTube, Display, Play): creative counts, countries, and the apps they land on.
What you can ask
- Does this product advertise on Google, and in how many countries?
- Which watchlist products only recently started buying Google ads?
- Which of Google, Meta and TikTok does each of these competitors advertise on?
These are example phrasings. Once connected, ask in plain language; the agent decides which table to query and how to filter.
Example: a real query and what it returned today
Your agent calls the MCP data tool like this (you never write it yourself — you just ask):
data(lib="googleads", args="advertisers --sort active --limit 8")
Advertisers with the most creatives shown in the last 7 days, first 8 rows:

Limits: what this data cannot tell you
Covers only products on our watchlist, not all advertisers; the advertiser-to-product mapping is ours and carries a confidence level.
It is a remote MCP server: sign in with Google, paste one prompt and your agent configures itself, then ask in plain language inside your project. Free during beta: 200 queries a day, up to 50 rows each.

How do I query it from Claude Code, Cursor or Codex?
It is one library inside the Stringers remote MCP server. Sign in with Google at stringers.io/en/start.html to get a personal URL, paste the prompt to your agent and it configures itself; then just ask — the agent calls the data tool with lib "googleads".
