IAB Tech Lab Agent & MCP Server Registry
IAB Tech Lab Agent & MCP Server Registry aims to bring trust and transparency to the Agentic Advertising ecosystem. Companies can register their MCP (Model Context Protocol) or A2A (Agents-to-Agents) agent(s), and browse for agents that they want to work with. Each agent can be associated with a set of standardized functions to make discovery easier, and each company is validated against their IAB Tech Lab GPP & TCF (Global Privacy Protocol) ID.
