The future of digital advertising just got its first rulebook. IAB Tech Lab’s Agent Registry – part of the new Agentic Advertising Management Protocols (AAMP) framework – has reached 10 active entries in just two weeks, with Amazon among the latest companies to register their AI advertising agents.
This marks a pivotal moment: the ad industry is building the infrastructure for AI agents to autonomously buy and sell media at scale.
The numbers so far:
What Is the AAMP Agent Registry?
A neutral, industry-managed discovery layer for agentic advertising – and the first real attempt to bring order to the autonomous ad buying ecosystem.
Launched on March 1, 2026, the IAB Tech Lab Agent Registry is essentially a phone book for AI agents – but one that also verifies identity, capabilities, and privacy compliance before any autonomous transaction takes place.
The broader AAMP initiative sits on three pillars: execution protocols, communication standards, and the Agent Registry itself. Every registered agent must provide a name, primary domain, and endpoint URL. Optional fields include up to 10 certification endorsements and links to existing privacy frameworks like GPP and TCF.
Currently, all 10 entries operate under the Model Context Protocol (MCP) standard, with zero Agent-to-Agent (A2A) entries registered so far. The registry also introduced a three-tier deployment classification system:
Three deployment types
Who Has Registered – and Why Amazon Matters
The registry’s first 10 entries span the entire advertising supply chain, from data providers to ad servers to supply-side platforms.
| Company | Type | Deployment |
|---|---|---|
| Amazon | Ad Server | Remote |
| PubMatic | SSP | Remote |
| Equativ | SSP | Remote |
| Optable | DMP | Private |
| Dstillery | Data Provider | Remote |
| Burt Corp | Analytics | Remote |
| HyperMindZ | Order Management | Remote |
| Mixpeek | DMP | Remote |
Amazon’s entry is especially significant. Their MCP server endpoint is publicly accessible without authentication, and it has been assigned “General Availability” maturity status. When the world’s largest advertising platform builds public AI agent infrastructure, it signals that agentic advertising is not a future concept – it is being built right now.
The timeline shows how quickly this ecosystem has evolved: from the Ad Context Protocol launch in October 2025, through LiveRamp’s User Context Protocol donation in November, to Amazon’s closed beta MCP server that same month, and finally AAMP’s formal naming on February 26, 2026.
Why This Changes the Game for Ad Spend
Agentic AI spending across all industries is projected to hit $201.9 billion in 2026. Within advertising specifically, the registry solves three critical problems.
Until now, AI agents operating in the ad ecosystem had no standardized way to verify who they were dealing with. The registry changes that by addressing three critical gaps:
Three problems the registry solves
Future registry features planned for the coming weeks include agent scoring and ratings, geographic filtering, and the ability to verify that seller agents actually represent a legitimate property.
What This Means for Marketers
If you manage paid media, this is the story to watch. The AAMP framework is laying the groundwork for AI agents that can autonomously negotiate, purchase, and optimize ad placements across platforms – all while maintaining compliance and transparency.
In practical terms, this means your media buying workflows are about to get a lot more automated. The brands and agencies that start understanding agentic advertising infrastructure now will have a significant head start when these systems reach mainstream adoption.
The immediate action item: Start evaluating how your current ad stack integrates with MCP standards and keep an eye on the IAB Tech Lab registry as it grows. The companies registering agents today are shaping the rules of tomorrow’s advertising ecosystem.
With Gartner predicting 40% of enterprise applications will embed AI agents by year-end 2026, the question is not if agentic ad buying will become standard – but how quickly.
