Every advertiser knows some of their budget is wasted. Almost none of them can say which part. Adrex answers that in about a minute — the campaign, the keyword, the amount, the evidence — and then helps you do something about it.
The core is a waste audit: it reads your ad accounts and reports how much of your spend returned nothing, ranked by size. The headline figure is a sum of your own spend, never a forecast — open your ad account and the numbers match. Around it sits a hosted platform with an autonomous optimization agent, budget rules and A/B experiments, plus an open-source MCP server that exposes the same tooling to Claude, Cursor and Codex.
Google's recommendations tab is a sales channel — it is structurally incapable of telling you to spend less. We have no such conflict, and most of what we find is spend to cut.
Read exactly what the MCP server does before it touches real ad accounts.
The audit changes nothing. Every step beyond it is opt-in, guardrailed, logged and reversible.
The headline is observed spend, not a model. Estimates are shown separately and never folded in.
We use OAuth for all platform connections, so your credentials never touch the MCP client. Tokens are encrypted at rest, all traffic is TLS, and infrastructure runs on Google Cloud with isolation per account. You can read our Privacy Policy and Terms of Service.
Create an account, connect Google Ads, and read your audit. Nothing is changed without your say-so. See the setup guide or browse use cases.
