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.
Launch of an open registry and validation tools from IAB Tech Lab provides infrastructure for agentic AI in advertising, improving discoverability, interoperability and transparency—meaningful for industry adoption but not as immediately disruptive as platform-level policy changes from major platform owners.

- Each registry entry is associated with the registering company’s GPP ID and IAB TCF GVL Ids; IAB Tech Lab will review entries and provides validation tools in the Tools Portal.
- The Tools Portal is free to register and offers both a UI and a documented REST API to browse and query registered agents.
- Early supporters registered at launch include Equativ and PubMatic; the registry operates as an MCP server so agents (e.g., Claude, Cursor or custom agents) can programmatically query it.

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.
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 Tech Lab Launches Unified Agentic Advertising Initiative
IAB Tech Lab announced the Agentic Advertising Management Protocols (AAMP), an umbrella initiative that groups its agentic standards, SDKs, and tooling for advertising. AAMP encompasses the Agentic Real‑Time Framework (ARTF), Agentic Audiences (formerly User Context Protocol), Buyer and Seller Agent SDKs, and other protocol work built on existing Tech Lab standards such as AdCOM and OpenDirect. IAB Tech Lab says ARTF is a high‑performance execution/control plane (claiming up to 90% latency reduction) while Agentic Protocols provide management schemas and reference implementations (Agentic Direct, Agentic Audiences, Agentic Mobile, Agentic Ad Objects). A third pillar, the Agent Registry, will provide agent identity, verification, and disclosure; the Registry is scheduled to launch next week. IAB Tech Lab previewed AAMP at its Agentic Bootcamp and unveiled it at Beet.TV’s Beet Retreat, and invites industry participants to join Agentic Task Forces for buyers, sellers, and audiences.
