AdBuyMCP turns one sentence about your customer into a costed plan across seven UK channels, from streaming TV and cinema to search and social. Every line carries a fidelity score for how precisely it reaches them and a manifest for the data that made it lawful, and Claude can run the whole loop through the MCP server under the same approvals and spend caps as the dashboard. The fee is 10% of media, dropping to 5% plus £749 a month above £25,000 of trailing 30-day spend. The whole loop runs today in a deterministic sandbox, and live spend is open to paid design partners.

AdBuyMCP is a UK media planning and buying platform that turns one sentence about your customer into a costed plan across TV, cinema, podcasts, billboards, search and social. It translates that sentence into the targeting each of the seven channels actually accepts (CTV and streaming, podcast and audio, addressable and linear TV, cinema, digital out-of-home, paid search and paid social), and every line carries a fidelity score for how much of your audience survived the trip and a lawful-basis manifest naming the data that made it legal. A job title travels well into a search auction and roughly onto a billboard, and the score shows you the difference before you fund either. Claude and other MCP clients can drive the whole loop through its MCP server, from brief and plan to launch and measurement, on the same REST routes, tenant boundary, spend caps and approval gates as the dashboard: the agent proposes, and a person approves anything that commits money. Search stays vendor-neutral while Google Ads and Microsoft Advertising execute it, and social stays vendor-neutral while Meta and TikTok execute it. Measurement keeps provider delivery, observed response, modelled estimates and powered causal evidence visibly apart, and the geo-lift engine refuses a test the spend cannot power. The fee is 10% of media, or 5% plus £749 a month above £25,000 of trailing 30-day spend, with the whole waterfall on the statement. AdBuyMCP is built and operated in London, and it is self-serve by design: you can plan in the browser with no account, and an approved five-question application opens a sandbox account where the whole loop runs today on deterministic data. Live spend is open to paid design partners.
