supply status

Check the evidence behind each connector before your plan relies on it.

We grade every connector on our own evidence ledger and name the step it is waiting on.

All 26 connectors run on labelled sample data in our sandbox, where the whole campaign workflow is tested end to end without spending money. Each one carries a grade from a 6-level evidence ledger that records what it has done with a real vendor, and no connector has yet run a paid campaign or reconciled a seller's report.

the evidence ladder

Each connector sits on one of six evidence levels

Each grade records what a vendor has actually done with the connector. Written code and stored credentials do not raise a grade on their own: a test against simulated vendor responses shows that a connector was built, and that is a level of its own. Each level below says what it takes to reach it, how many connectors are on it and which ones. The top two levels are empty, and they can be filled only with a dated evidence record of a paid activation or a reconciled report.

level 1 of 6
0
of 26 connectors
Sandbox only
Fixed, labelled sample behaviour for planning. Everything it returns comes from the sandbox, and nothing from a vendor.
No connector sits here as a whole, which is why the count is zero. The level is reached inside connectors, on single operations with no live path at all: StackAdapt's inventory browse and Vibe's forecast both return sandbox data, on connectors whose other operations do not.
level 2 of 6
3
of 26 connectors
Stub
The connector models the vendor's shapes and drives the sandbox. Every live method fails closed before it makes a vendor call. Each stub is waiting on a contract, a seat or a published schema.

the ledger

Every connector names the step it is waiting on

The connectors behind out-of-home, streaming TV and podcasts come first, and the rest of the ledger follows. Within each part, connectors are grouped by kind, because each kind waits on something different: a buying API on a contract and a capped test, a booking workflow on a sales house's first delivery statement, an audience source on a data licence, and a measurement source on a campaign with results in it.

Sixteen of the 26 connectors buy, target or measure the channels a plan runs on.

ChatGPT ads

ChatGPT ads has no connector in this ledger. OpenAI asks each advertiser to open and verify its own ChatGPT ads account and to invite whoever runs it, so your ChatGPT ads run in your own account, set up with you. AdBuyMCP has no OpenAI partner status.

Buying APIs

7 of 26 · 1 stub · 5 client built · 1 contract tested · 0 spend tested

The seller publishes a buying API, and the connector calls it directly. Its grade says how far that connection has been tested with the seller.

Evidence grade and next step for each connector in this group: Buying APIs.
Vendor	What it is	Channels	Evidence grade	What it is waiting on

Perion (Hivestack)P0	What it isProgrammatic DOOH.	ChannelsDOOH	Evidence gradeClient builtlevel 3 of 6	Waiting on Live activation requires hand-picked Hivestack unit ids: venue and postcode semantics have no verified vendor-id translation.

Its own gate: verify the stopped campaign and strategy readback and the human-approved publish and enable sequence on the authorised US account, then reconcile a controlled test buy and its asynchronous report. Access US inventory in USD only. The adapter refuses a non-USD budget outright, and this rail is deferred from the UK queue until that changes. Those 549 units are US units.

Booking workflows

live vendor evidence

One connector (Vibe, on 13 August 2026) has had read-only calls accepted by a live vendor API, and no other connector has any live vendor evidence. No connector has executed a buy.

where the grades come from: The product's own evidence record, read connector by connector, so this page shows the grade the product itself holds.
how a connector reaches the top grades: By clearing every go-live step below, in order, ending with spend reconciled to the seller's invoice. Describing a connector differently cannot move it.

the go-live standard

A connector clears these steps before we call it live

A connector clears these six steps in order, and each step leaves a record.

01
We hold the contract and probe the approved account
The supplier contract and the account's scope are in place, the credentials are saved encrypted, and a probe runs against that approved account. The accepted request and response shapes, permissions, currency, account identity and the way a repeated request is handled are recorded in a supplier record tied to that connection.
02
Everything is staged paused
The first activation creates the campaign, its ad groups and its ads paused, or in the seller's equivalent state, and records every id the seller returns in an exact list of what was staged. Everything stays paused until a separate grant resumes it.
03
A named person approves the exact creative
A named person records the seller's decision on the exact creative file, its fixed destination and the seller's reference. Approval records a decision; only the grant in the next step can start spend.
04
A separate grant switches it on
Resuming is a separately granted action. It first checks that what the seller holds still matches the staged list exactly, with nothing added, missing or swapped, and that the seller account is the one the credentials and the staged campaign belong to. A mismatch stops it before anything is written.
05
A capped test runs and a failure is rehearsed
A small test runs against a capped commitment, delivery is confirmed in the seller's own interface, the emergency pause is used, and both a clean outcome and an ambiguous one are reconciled. An ambiguous outcome goes to a person.
06
Spend is reconciled to the seller's invoice
A non-empty report is pulled from the seller with its own dimensions and currency intact, and spend is reconciled to the seller's invoice or account total, with the exact export uploaded by a named person. Only then can a connector move to spend-tested and report-verified.

The separately granted resume holds the sequence together. Approving the creative records a decision and cannot start spend on its own, and a campaign whose structure has changed since it was staged stops before anything is written.

Launch phase

Price a plan today and join the waitlist; media is bought only after your plan is confirmed with you

The grades above are where each connector stands today. The first campaigns run on start dates agreed with each founder, so if yours has to start by a fixed date, agree that date with James Rooney before you confirm your plan.

The words this ledger uses

Founders ask these questions about the connectors

Each answer comes from the same evidence ledger as the rows above.

Can I buy media through AdBuyMCP today?

You can price a plan today and join the waitlist, with no card. 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.

What does client-built actually mean?

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.

Which connectors have had a real vendor accept a real call?

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.

Why are some connectors booking workflows rather than APIs?

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.

Does AdBuyMCP have a live Vistar connector?

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.

Do you buy ITV, Sky or Channel 4?

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.

What happens if a supplier's authority expires mid-campaign?

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.
