These answers cover what you can do today.

You can size your market and price a plan today, free, then join the waitlist. Joining the waitlist takes a short form and no card. James is setting the first customers up himself, so he reads every entry and comes back to you, and nothing is bought until the plan, the ads and the start date are confirmed with you. No media has been bought through AdBuyMCP yet. The supply page shows how far buying through each seller has been tested. A campaign you start now would be among the first bought through AdBuyMCP, on a start date agreed with you.

Not yet. No paid campaign has run through AdBuyMCP's own connectors, so there are no case studies or references to offer. What you can check instead is the price for your own market, worked out from the published rate before you join, the sourced research behind the offer, and the grade of every connector on the supply page at https://adbuymcp.com/supply.

You should know four things before you buy. No paid campaign has run through AdBuyMCP's own connectors yet, so yours would be among the first. Frequency is planned: we buy enough ads for your market to see you that often on average, and no seller can confirm that each person did. ChatGPT ads run in your own OpenAI ad account, and outside the US, OpenAI generally prohibits financial and health services ads and prohibits legal services ads. And there is no account team, support SLA or status page: you talk to the founder.

Each one is a fact about the product today, taken from the page that holds its evidence. The supply page grades each connector on what it has done with a real vendor, the security page records the controls in force and what is not held, and the measurement page sets out what each channel reports. A limit changes only when the evidence behind it does.

Stop if your procurement team requires a certification, if verified quality reporting is a condition of your plan, or if you sell financial, health or legal services and need ChatGPT ads, which OpenAI's policy restricts outside the US. Awareness is also the wrong buy if most of your buyers are outside the UK or you need meetings this month: search and outbound reach the buyers who are looking now.

It has to clear the six go-live steps on the supply page, in order, from the seller's contract and a probe of the approved account to spend reconciled against the seller's invoice, with a capped paid test and a rehearsed failure on the way. Until a connector clears every step, the supply page describes it as built and names the step it is waiting on.

No. Pricing a plan and joining the waitlist are free, with no card. A plan costs the all-in monthly price shown when you confirm it, which covers the ads AdBuyMCP makes for each channel from your website.

James is setting the first customers up one at a time, so he reads every entry and comes back to you, and media is bought only after your plan, your ads and your start date are confirmed with you. No connector has yet run a paid campaign: none has reached spend-tested or report-verified on our evidence ledger, so a campaign you start now would be among the first, on a start date agreed with you.

That a live connection to the vendor is written and passes tests against simulated vendor responses. Those tests show the connector was built. A vendor accepting a request, money moving and a report reconciled to an invoice are three separate grades above it. 22 of the 26 connectors sit at client-built, and none has reached either of the top two grades.

One. Vibe, on 13 August 2026: OAuth, advertiser discovery and a 549-unit catalogue read, all read-only and all US inventory. Its own next step is to verify the stopped campaign readback and the human-approved publish and enable sequence on the authorised US account, then reconcile a controlled test buy and its asynchronous report. Within that same connector, activation, pause, resume, creative and reporting are still client-built.

Because some sellers take bookings through a sales house rather than a self-serve buying API. For podcasts, that means Acast's named-show and private-marketplace packages and deals on Global's DAX: the connector prepares the paperwork, and the sales house confirms each booking and reports the delivery. The other booking workflows in the ledger work the same way. No booking workflow has had a delivery reconciled yet.

No. Vistar's connector is a stub: forecast, activation, pause, creative submission, reporting and inventory listing all stop before any request reaches Vistar, so it plans with sandbox data only. It is waiting on an approved trafficking seat and a separate bidder approval, both of which Vistar grants to partners.

No. The Universal Ads connector, which would cover that inventory through one partnership, is a stub: every live method stops before it calls Universal Ads, and it is waiting on partner approval and a per-request signing key, neither of which exists. Sky AdSmart and ITV Planet V are booking workflows in the ledger: the connector prepares the brief and the sales house makes the booking, and no delivery has been reconciled through either.

Spend stops. An expired or blocked supplier record raises a spend lock before any scheduled work runs, sends one emergency pause tied to that incident, and refuses to retry an ambiguous response. Only a named person's reconciliation clears it, and verifying again then revoking again opens a new incident.
