On June 24, 2026, a media company purchaser in Prague typed a marketing campaign transient into ChatGPT – and the remaining occurred with out a human contact. Stock was matched, phrases had been negotiated, and the acquisition was executed end-to-end by autonomous AI brokers. No spreadsheets. No procurement calls. The Czech Republic’s first absolutely agentic advert purchase was full.

What occurred and who was concerned

R2B2, an promoting expertise firm headquartered in Prague and based in 2014, facilitated the transaction between Omnicom Media, the Czech operation of the worldwide Omnicom Group, and MAFRA, one of many nation’s main digital publishers. The advertiser behind the marketing campaign was Skylink, a Czech satellite tv for pc pay-TV service that operates as a part of the European tv group Canal+.

In response to R2B2, this marks the primary time any autonomous AI agent has executed an entire advert area buy within the Czech Republic with out handbook intervention on the transactional stage. The pilot is the primary public demonstration of what R2B2 calls “agentic promoting” within the CEE area.

The size of the pilot is modest – one marketing campaign, one purchaser, one writer. What issues is the structure it demonstrates, and what that structure implies for a way media buying and selling may function at scale throughout European markets.

How the transaction truly labored

The mechanics deserve shut consideration. Relatively than navigating stock spreadsheets or negotiating phrases through e-mail or cellphone, the customer at Omnicom Media used ChatGPT as a conversational interface. By describing the marketing campaign’s goals and concentrating on necessities in pure language, the customer triggered a series of automated actions that culminated in a accomplished media buy.

R2B2 performed the function of what it describes because the “sell-side agent” – the technical middleman between the shopping for AI and MAFRA’s present advert server. The connection between these two sides was made potential by way of a proprietary, internally developed MCP (Mannequin Context Protocol) gateway that R2B2 constructed on prime of its monetization infrastructure.

MCP, or Mannequin Context Protocol, was initially developed by Anthropic and subsequently donated to the Linux Basis. It has emerged over the previous 18 months as a connective commonplace throughout the programmatic promoting trade. PPC Land has tracked its adoption across advertising infrastructure throughout 2025 and into 2026, with platforms together with AdRoll, PubMatic, FreeWheel, Yahoo DSP, and DoubleVerify all constructing MCP-based integrations for marketing campaign administration, deal diagnostics, and optimization workflows.

Within the R2B2 implementation, the shopping for agent – working by way of ChatGPT – communicated with R2B2’s MCP gateway utilizing a separate protocol layer referred to as the Advert Context Protocol (AdCP). The AdCP is an open-source specification constructed on prime of MCP, launched on October 15, 2025 by a coalition of six founding firms – PubMatic, Scope3, Swivel, Triton Digital, Optable, and Yahoo – particularly to standardize how AI brokers talk throughout promoting platforms. In response to R2B2, its pilot used AdCP to manipulate the interplay mannequin between the shopping for agent and its sell-side gateway.

All the answer runs as a managed cloud-based SaaS service, which R2B2 says successfully removes technical obstacles for publishers that need to take part in agentic transactions. Crucially, the combination is fully server-to-server. No client-side scripts are concerned. In response to R2B2, this implies zero latency impression on MAFRA’s net pages and no disruption to the person expertise of the writer’s viewers.

This server-to-server structure is a significant technical element. Shopper-side integrations carry actual prices: extra JavaScript on a web page provides load time, and publishers with strict efficiency targets have traditionally resisted including new tags. A server-to-server strategy sidesteps that objection fully.

The function of ChatGPT because the shopping for interface

The choice to make use of ChatGPT because the buyer-facing interface is value inspecting individually from the infrastructure layer. ChatGPT is just not a specialist promoting instrument. It’s a general-purpose massive language mannequin assistant. By connecting it to R2B2’s MCP gateway by way of the AdCP, Omnicom Media demonstrated that the customer’s interface might be any AI assistant able to utilizing MCP – not a bespoke promoting platform.

This issues as a result of it implies a future during which the shopping for facet of programmatic promoting turns into accessible by way of no matter conversational AI instrument a media planner already makes use of. The specialist interface – the DSP dashboard, the proposal type, the spreadsheet request for proposal – turns into optionally available if the MCP gateway is in place on the promote facet and the customer’s AI assistant can uncover and name it.

The agentic advertising trajectory has been visible across the industry since mid-2025, when analysts started modelling eventualities during which AI brokers bypass conventional demand-side platforms fully. On this Czech pilot, there isn’t any DSP within the transaction chain in any respect. The shopping for agent communicated immediately with R2B2’s sell-side infrastructure.

Human oversight constructed into the workflow

The pilot didn’t take away people from the method fully. In response to R2B2, publishers retain the ultimate say: each marketing campaign and inventive asset have to be manually authorised by MAFRA earlier than it goes dwell. That is what the trade describes as a “human-in-the-loop” design – excessive automation within the discovery and negotiation levels, human approval on the level of activation.

“Our purpose was to create a safe, intuitive atmosphere the place each events can function seamlessly with out disrupting established approval workflows,” mentioned Lukáš Alexandr, CTO at R2B2.

That framing displays a structural selection about the place within the workflow human oversight provides most worth. Within the pilot, people aren’t wanted to navigate stock or negotiate phrases – however they maintain management over what runs, and the place. MAFRA’s David Korn, Business Director, confirmed that the pilot efficiently verified their infrastructure’s readiness for AI brokers, and that automated transactions posed no danger to net operations, in keeping with R2B2.

The human-in-the-loop design has change into one thing of a consensus sample amongst early agentic promoting implementations. Yahoo DSP integrated agentic AI capabilities on January 6, 2026, with its troubleshooting agent in a position to diagnose and advocate corrective actions however requiring human approval to execute them. That sequencing – agent proposes, human approves – is identical logic R2B2 utilized on the level of marketing campaign activation.

Jindrich Jiracek, Head of Efficiency at Omnicom Media, described the strategy this manner in remarks attributed to him by R2B2: “We view agentic shopping for because the pure evolution of digital promoting. This expertise has the potential to dismantle long-standing obstacles between marketing campaign briefing, stock choice, and execution. It opens new frontiers for automation and collaboration whereas preserving the human strategic oversight that’s very important for our decision-making.”

The remark displays a selected operational downside that the agentic strategy is meant to deal with. In standard media shopping for, the hole between a marketing campaign transient and dwell stock is commonly measured in days – a number of rounds of communication, inside approval steps, counter-proposals from publishers, inventive trafficking. Agentic instruments compress that timeline.

Tomas Jelinek, Acquisition Advertising and marketing Supervisor at Skylink, supplied a direct-advertiser perspective in remarks attributed to him by R2B2: “At Skylink, we’re repeatedly on the lookout for new methods to succeed in related audiences extra successfully whereas sustaining a high-quality media atmosphere. We see the agentic shopping for pilot as an attention-grabbing step towards better automation, sooner work with out there stock, and extra exact alignment of the marketing campaign with the suitable context. What’s essential for us is that even when utilizing superior expertise, we preserve management over the place and the way our model is displayed.”

The emphasis on model management is in keeping with how advertisers throughout the market have positioned themselves relative to agentic instruments. Autonomy in execution is accepted; autonomy in model placement selections is just not.

The AdCP commonplace and the place this suits within the broader panorama

Using AdCP within the Czech pilot is notable in itself. The Ad Context Protocol launched on October 15, 2025, with appreciable trade debate about whether or not it addressed elementary structural issues or merely added one other protocol layer on prime of present fragmentation. Outstanding critics on the time famous that main demand-side platforms – Google, Amazon, The Commerce Desk, and Microsoft – didn’t join AdCP, elevating questions on how broadly the usual may realistically be adopted.

Since then, proof of AdCP-based dwell exercise has been accumulating. VIOOH’s Vendor Agent automated greater than 100 curated digital out-of-home non-public market deal packages within the first half of 2026 utilizing infrastructure aligned with AdCP. Broadsign and Draft Digital ran the first reported fully agentic out-of-home campaign in Could 2026 utilizing AdCP. PubMatic’s AgenticOS launched in January 2026 with dwell campaigns working throughout WPP Media, Butler/Until, and MiQ.

The R2B2 pilot provides a brand new sort of deployment to that report. The place earlier AdCP-based dwell exercise has primarily occurred in the USA and in digital out-of-home stock, the Czech marketing campaign demonstrates the protocol working for normal digital show promoting in a Central European market, with a mid-size regional writer and a pay-TV advertiser – neither of which inserts the early-adopter profile of the infrastructure firms that designed the protocol.

R2B2 is just not itself an AdCP founding member or a big platform. It’s a expertise firm working throughout 46 markets with a focus in CEE, which it constructed by way of proprietary monetization instruments since its founding in 2014. Its MCP gateway is an internally developed product fairly than a direct implementation of a significant platform’s infrastructure. That independence is a part of what makes the Czech pilot significant. If agentic promoting requires both deep pockets or founding-member standing in a significant protocol consortium, its adoption will stay gradual. If a mid-size regional advert tech firm can construct a working implementation that executes a dwell transaction, the strategy is extra accessible than the infrastructure debate suggests.

R2B2’s scale and what comes subsequent

R2B2 describes itself as working infrastructure throughout 46 markets. The corporate’s said focus is the CEE area, the place it has developed relationships with publishers and companies over greater than a decade. That regional footprint is related to what occurs after a pilot.

In response to R2B2, the plan is to scale the platform by onboarding extra publishers and persevering with to refine the combination. The corporate has not disclosed timelines or the particular publishers it’s concentrating on. Lukáš Alexandr, CTO at R2B2, described the course of journey in remarks attributed to him: “Synthetic intelligence and autonomous, agentic buying are the clear way forward for digital promoting. Publishers and advertisers alike want to arrange, as this methodology of buying and selling advert area is poised to change into the brand new market commonplace.”

That forecast is in keeping with the sample that PPC Land has documented throughout the trade by way of the primary half of 2026. Agentic promoting is not theoretical. It’s working dwell campaigns. What stays genuinely unsure is the tempo at which the operational mannequin spreads from early contributors – technically refined companies, platform-native publishers, and devoted advert tech firms constructing the infrastructure – to the broader market of consumers and sellers who haven’t but begun getting ready.

The IAB Europe CTV programmatic guide from April 2026, which included a Czech case examine involving Skylink, OMC Czech Republic, and Adform, documented a market already participating with advanced programmatic constructions. That the identical Czech market now has the primary agentic direct purchase on report is just not a coincidence – it displays real exercise amongst Czech market contributors in programmatic infrastructure, throughout each show and linked tv.

Omnicom itself has been shifting on a number of agentic fronts concurrently. At Cannes Lions 2026 in late June, Adobe introduced that Omnicom is deploying an AI Agentic Operating Model throughout 4 trade verticals – automotive, prescription drugs, retail, and monetary providers – as a part of a broader enterprise implementation of Adobe’s agentic infrastructure. The Czech pilot and the Cannes announcement are separate tracks, however they mirror the identical strategic course contained in the holding firm.

Why this issues for European markets

European markets have adopted a distinct trajectory from the US in programmatic promoting, formed by GDPR, market fragmentation throughout languages and regulatory environments, and a writer panorama that differs considerably from the open-web show market in North America.

The Czech pilot is the primary publicly documented occasion of absolutely autonomous agentic advert shopping for in a Central European market. That could be a particular geographic and regulatory context. MAFRA operates in an atmosphere the place information dealing with, consent, and model security requirements observe EU frameworks. The R2B2 integration is server-to-server, which means it doesn’t contain client-side information assortment. Mixed with the human approval requirement for inventive property, the structure as described is designed to function inside publisher-controlled environments fairly than requiring publishers to increase belief to opaque automated techniques.

Whether or not the mannequin spreads throughout the CEE area relies upon partly on how different publishers assess their very own infrastructure readiness. David Korn’s affirmation that the pilot verified MAFRA’s infrastructure readiness for AI brokers is an information level different publishers within the area will likely be watching.

Timeline

Abstract

Who: R2B2 (promoting expertise firm, Prague, based 2014, working throughout 46 markets), Omnicom Media (Czech operation of the worldwide Omnicom Group), MAFRA (Czech digital writer), and Skylink (Czech satellite tv for pc pay-TV service, a part of Canal+).

What: The Czech Republic’s first absolutely autonomous AI agent advert purchase, executed by way of a ChatGPT interface linked to R2B2’s proprietary MCP gateway and the Advert Context Protocol, with MAFRA as writer and Skylink as the tip advertiser. The transaction lined stock identification, negotiation, and execution with out handbook intervention within the transactional levels – although human approval of inventive property was retained at MAFRA’s finish.

When: The transaction was executed on June 24, 2026, and publicly introduced the identical day.

The place: Prague, Czech Republic. The technical transaction was server-to-server, involving no client-side scripts and inflicting no latency impression on MAFRA’s net properties.

Why: R2B2 designed the pilot to display that agentic promoting – autonomous AI-driven media shopping for utilizing open protocols – is technically possible for normal digital promoting in a Central European market, not solely within the US show and CTV environments the place most agentic deployments have occurred to this point. For Omnicom Media and Skylink, the pilot assessments whether or not AI-mediated execution can compress the timeline between marketing campaign transient and dwell stock with out sacrificing model management or writer approval workflows.
