Agentic AI Advertising: Why Connectivity, Standards, and Control Matter
The article discusses the evolution of agentic AI in advertising, focusing on the need for connectivity and standards. IAB UK reports that only 4% of marketing operations are currently agentic, while 74% of members are experimenting. Onetag introduces an MCP gateway to unify platform modules, enabling AI assistants to access tools via a single connection. The gateway routes requests, applies existing permissions, and maintains resilience. Onetag is adopting IAB Tech Lab's AAMP framework to ensure approval gates and pricing verification. The article emphasizes that human oversight remains crucial, as agents need clearly defined boundaries and accountability.
The article highlights a significant technical development in agentic AI for advertising, introducing a new MCP gateway and adoption of AAMP standards, which could shape future industry practices.

Agentic Advertising Needs Standards and Interoperability
Jonas Jaanimagi (Tech Lead, IAB Australia) argues that the ad industry must prioritise interoperability, standardisation and broad adoption to realise the promise of agentic advertising. The IAB Tech Lab’s new Agentic Advertising initiative — AAMP (Agentic Advertising Management Protocols) — provides specifications, protocols, APIs and reference implementations to 'agentify' existing standards such as OpenRTB, OpenDirect and AdCOM. Core interoperability protocols cited include MCP (Model Context Protocol) and the A2A Agent‑to‑Agent protocol. The Agent Registry, launched in March 2026 and available via the IAB Tech Lab Tools Portal, aims to provide public discoverability, identity and verification for agents to increase transparency and reduce fraudulent autonomous activity. The piece emphasises open‑source collaboration, governance, human oversight, and industry-wide adoption to prevent fragmentation, enable secure agentic workflows and accelerate practical benefits like faster media planning, smarter discovery and more efficient direct deals.
Leverage Existing Standards for Faster Agentic AI in Ads
This opinion piece argues that agentic AI will reshape advertising but requires deterministic schemas and industry standards to operate reliably. It warns against inventing new, incompatible schemas and instead advocates using established IAB Tech Lab standards and taxonomies — including OpenDirect, AdCOM and OpenRTB — plus emerging agent protocols like the Model Context Protocol (MCP) and Agent-to-Agent (A2A). The article says standards provide the shared, referenceable definitions agents need to avoid compounding hallucinations, misclassified inventory, and fraud. The IAB Tech Lab’s phased ‘Agentic’ roadmap will begin by improving inventory discovery for agencies and advertisers, then expand semi-autonomous workflows built on interoperable, standards-compliant agents.
AI-Driven Advertising: A New Era of Autonomy
IAB Tech Lab published a position and roadmap arguing that an agentic, AI-driven future for advertising must be grounded in existing deterministic standards and shared object models. The paper (and associated keynote referenced) explains how large language models and agentic systems can reduce friction across advertisers, agencies, publishers and users — but warns agents will fail without precise schemas. IAB Tech Lab promotes building on existing IAB standards (AdCOM, OpenRTB, OpenDirect, Ad Management API, Deals API) and Tech Lab taxonomies (Audience, Content, Privacy), and outlines an Agentic Roadmap with near-term use cases, sample agents and MCP server reference implementations. It also highlights agent coordination protocols such as A2A and MCP and notes these protocols are nascent (barely a year old).
