design-partner phase

What we do not claim

Every limit on this product, on one page, with the evidence beside it.

AdBuyMCP is in its design-partner phase. The whole loop runs today in a deterministic sandbox that needs no credentials and no card, and no buying rail has yet spent money or reconciled a real report against a provider invoice. This page collects everything that is not finished, not held, or not proven, so that the rest of the site can get on with describing what is.

before the list

What is finished, and what that is worth

This fold is here so the rest of the page is read as a description of a product that is early rather than one that is failing. Everything below runs today, and none of it is waiting on a rail being spend-tested.

The sandbox is complete and deterministic

Every adapter, the AI planner and the whole measurement stack produce deterministic, repeatable data with no API keys. You can run brief to plan to launch to measurement end to end before anyone asks you for a credential. Every impression, reach, CPM and delivery row it shows you is sandbox output, labelled as such — a working product, not a forecast.

Live rails are built, not proven

We grade every connector on a six-level evidence ledger. Of 25: 18 are client-built, 6 are stubs that make no vendor call at all, and 1 — Vibe — has had read-only calls accepted by a live vendor. Nothing has reached spend-tested or report-verified, and a continuous-integration check keeps those two counts at zero until something genuinely earns them.

Cinema and addressable TV are paperwork, automated

DCM cinema and Sky AdSmart have no self-serve APIs, and we do not pretend otherwise. We generate the booking brief, drive the clearance step and hold the IO state machine. We do not make the booking and we do not report the delivery. Every live step is acknowledged by a named person quoting the sales house's own reference, and no live step advances on a timer.

No customer case studies yet

There are none, so we publish none. What you get instead is the sandbox, the supply matrix, the fee waterfall and the methodology — the evidence that actually exists.

the list itself

8 things this product does not do yet.

Each one names the limit, what it means in practice, and the page carrying the full evidence where there is one. Nothing here has a date against it. A roadmap treatment would turn a list of facts into a list of promises, and no such promises have been made.

  1. 01

    You cannot buy media self-serve here today

    No buying rail has cleared our own launch standard, which requires a contracted supplier request accepted, a controlled paid activation, immutable creative identity, report rows reconciled to an invoice, and a rehearsed failure. Live spend sits behind a design-partner engagement rather than a signup form. The sandbox is complete, free, and needs no credentials.

  2. 02

    No security or privacy certification

    No ISO 27001, no SOC 2, no Cyber Essentials, no penetration test and no completed DPIA. Legal documents are templated pending counsel. 11 items are published as not held, each with its status and what would have to happen to change it.

    the evidence →
  3. 03

    No account team, no SLA, no status page

    There is no support SLA, no escalation path, no status page and no named launch specialist. These are unbuilt rather than unmentioned. What there is instead is direct access to the people building the product, which is worth more at this stage and less at every stage after it.

  4. 04

    No customer outcomes, references or case studies

    There are none, so we publish none. No logos, no testimonials, no named references and no reconciled outcome study. That is where a product recruiting its first design partners actually is, and a logo wall would be the fastest way to make everything else on this site worth less.

  5. 05

    No verified media quality layer

    Brand safety, viewability and fraud verification are not integrated, and no third-party verification vendor is wired in. If your media plan requires verified quality reporting, that requirement is not met here yet.

  6. 06

    The exposure ledger has no live input

    The spine behind cross-channel deduplication is schema-backed and unit-tested, and is fed only by the deterministic sandbox. It is a working mechanism with nothing real flowing through it.

    the evidence →
  7. 07

    No published lift or incrementality figure

    There is no result to publish, and the geo-lift engine refuses to run a test the spend cannot power rather than returning a number it cannot stand behind. What is on offer is the refusal and the method, not a percentage.

    the evidence →
  8. 08

    The MCP server is self-hosted and single-tenant

    There is no public or hosted connector. Authentication is a static bearer token, suitable only for a private single-tenant deployment; per-user OAuth with PKCE and consent is an open launch gate rather than a shipped feature.

money, specifically

Four things worth knowing before you spend anything

These come from our own go-to-market review, which was written to be read internally and is harder on the product than a marketing page would normally be. Three of the four are things a buyer works out in the first month, and the published band starting at £2,000 is the one most likely to mislead without the paragraph beside it.

Below about £10,000 a month, this is the wrong product

The published band starts at £2,000, and at that end the maths does not work for either of us. A 10% fee on £2,000 is £200 a month against a buyer who needs the most support, and a seven-channel plan at that budget is operationally and statistically weak — too thin to pace properly and far too thin to power a lift test. If your total monthly media is under £10,000, buy search and social directly, and come back when you have a second channel worth funding.

The fee is not the whole cost of the media

Data segments carry their own CPM uplift — around £2.50 per thousand on Bombora topics and £3.00 on Dun & Bradstreet — and every channel has a plan floor enforced when the plan is built: £100 on search and DOOH, £140 a week on CTV, £250 on audio and social, £500 a week on cinema, £1,000 on addressable TV. Vendor-side minimums are separate and bite later; Sky AdSmart's £3,000 burst is the one most likely to surprise a first plan. Those are the sellers' costs rather than ours, and you see them before you approve rather than in the reconciliation afterwards.

You cannot fund live media from a top-up yet

The sandbox is complete and free — brief, compiled plans, creative, approval, delivery and reconciliation, with no credentials and no card. Funding real media sits behind a design-partner engagement instead, and no fee has ever been charged to a real customer. The supply page grades every rail, including the two grades nothing has reached.

There is no published customer outcome yet

No case studies, no reconciled outcome study, no named reference — that is where a product recruiting its first design partners is. What exists instead is a sandbox that produces plans and delivery rows rather than results, and a measurement engine that returns an underpowered verdict and the sample it would need instead of a lift figure it cannot support.

questions

What people ask about this page

Why publish a page of your own limitations?

Because a buyer evaluating a new media platform is running one question — can this actually buy the thing it says it buys — and every platform they have evaluated answered it with a logo wall. A logo wall is unfalsifiable, so it is worthless as evidence, so the buyer discounts it and asks in the call anyway. Publishing the grade ledger, the certifications not held and the floor below which we are the wrong product costs us the visitors who wanted to spend tonight, which is a cohort this product cannot serve, and it buys credibility with the cohort it can.

Is anything on this site actually working today?

Yes, and it is the majority of the product. The whole loop — brief, persona, seven compiled plans, creative, approval, launch, delivery, measurement, journeys and optimisation — runs end to end in a deterministic sandbox with no credentials and no card, and it returns repeatable data rather than a scripted demo. What is not ready is ordinary customer spend on live rails, which is why live buying sits behind a design-partner engagement.

What would have to change for a rail to be called live?

Five things, in order: a contracted supplier request accepted by the vendor, a controlled paid activation, immutable creative identity through the buy, report rows reconciled against a provider invoice, and a rehearsed failure. Until a rail clears all five it is described on this site as built rather than as live, and the supply page names the specific blocker standing in front of each one.

Do you charge for the sandbox?

No. It needs no credentials and no card, and there is nothing to sign. Charges begin at real media and at real asset generation, both of which incur a cost to somebody else.

having read all that

The sandbox is still the fastest way to judge this.

Bring a real brief to a working session and watch it compile into seven costed plans, with the fidelity score and the lawful-basis manifest on screen. It runs in the deterministic sandbox, so it needs no credentials and no card, and you leave with the plans either way.
