IAB Tech Lab Launches Agent Registry for Advertising Agents
The IAB Tech Lab announced a new Agent Registry designed to catalog, verify and make discoverable advertising-focused AI agents. The registry links registered companies to IAB GPP IDs and IAB TCF Global Vendor List IDs for validation and is implemented as an MCP server, allowing machine-readable queries by agents and platforms. Early registrants include Equativ and PubMatic. The registry will cover categories such as DSP, Identity Resolution, Measurement & Attribution, CDP and Consent Management, and the roadmap includes agent scoring/ratings, geographic filters, support for private/local deployments, and a seller-agent verification mechanism likened to an ads.txt equivalent for agents.
A standards/registry release from the IAB Tech Lab creates discoverability, verification and machine-readable interfaces for agentic advertising — infrastructure that can materially affect programmatic workflows, trust, and identity in the ad ecosystem.

IAB Tech Lab Launches Comprehensive Agent Registry for AdTech
IAB Tech Lab announced the launch of its Agent Registry as part of the Tools Portal to catalog and validate Agentic Advertising agents built under the AAMP initiative. The registry lets companies register MCP and A2A agents, assign Tech Lab–defined categories (e.g., DSP, Identity Resolution, Measurement & Attribution, CDP, Consent Management), describe agent capabilities and maturity, and link each entry to the company's GPP ID and IAB TCF GVL IDs for validation. The Tools Portal (free to register) offers a UI and a documented REST API, and the registry itself runs as an MCP server so other agents can query it. Early supporters named include Equativ and PubMatic. IAB Tech Lab noted additional features (ratings, geo flags, private tenants, seller verification, update flows) are planned in coming weeks.
IAB Tech Lab Reports AAMP Progress After Two Months
Two months after launching the Agentic Roadmap (now AAMP — Agentic Advertising Management Protocols), IAB Tech Lab reports early industry adoption and technical progress. Buy- and sell-side Agent SDKs are available and being integrated (notably Kochava’s use in StationOne), an IAB Tech Lab Agent Registry is live and already contains registered agents from vendors including Amazon Ads and PubMatic, and the Registry functions as an MCP server interoperable with chatbots like Claude, Gemini and ChatGPT. The Seller Agent SDK includes pre-built integrations with PubMatic and Index Exchange (and FreeWheel for CTV/video). IAB Tech Lab also enabled an OpenRTB extension to support “Agentic Audiences,” a privacy-focused ephemeral audience representation donated by LiveRamp. More announcements are planned ahead of the Tech Lab Summit on May 28 in NYC.
IAB developing framework for AI ad measurement
The IAB is developing a framework to measure AI's influence on consumer conversions, set for release on November 12. The framework classifies how AI impacts purchase decisions and attributes conversions to AI touchpoints, including when ads weren't directly served to AI agents. Led by VP of AI Caroline Giegerich and informed by an undisclosed working group of tech companies, publishers, agencies, measurement vendors, and brands, the effort builds on IAB's August 'Measuring Visibility in the AI Era' guideline and complements IAB Tech Lab's Agentic Advertising Management Protocols (AAMP). Key challenges include data access from platforms like OpenAI, Google, and Anthropic, and debates over signal control. Industry data underscores urgency: Adobe reported a 393% year-over-year surge in AI-sourced traffic, while a Koddi study found 80% of German commerce media executives want better measurement tools for AI-agent shopping journeys.
