# Google Ads Transparency tracker: an MCP database you can query from Claude Code or Cursor

Updated daily, last 2026-11-12 · MCP `data` · lib `googleads`

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:

| name | country | active_7d | new_7d | n_creatives | first_shown | watch |
|---|---|---|---|---|---|---|
| Next Vision Limited | HK | 1000 | 18 | 1263 | 2022-08-13 | Woodsense: Wood Plans & Guides |
| KOLSUP LIMITED | HK | 1000 | 139 | 1007 | 2026-08-18 |  |
| Spotter, Inc. | US | 774 | 69 | 1014 | 2026-05-08 | Soluna |
| Wispr AI, Inc | US | 750 | 3 | 1278 | 2025-03-03 | Wispr Flow |
| Moises Systems, Inc. | US | 727 | 32 | 1037 | 2023-01-26 | Moises.ai |
| Hong Kong AdsMarch TECHNOLOGY LIMITED | HK | 618 | 56 | 1026 | 2022-08-13 |  |

| Adcore East Limited | HK | 577 | 25 | 1125 | 2022-10-13 | Coddy Build / Grizzly SMS: Virtual Numbers |

## How fresh the data is

This is today’s output of `coverage` (row counts and date ranges per table):

| tbl | n_rows | first | last |
|---|---|---|---|
| watch(名单) | 2831 | 2026-11-02 | 2026-11-11 |
| watch 查过 | 1459 | 2026-11-02 | 2026-11-11 |

## 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.
