Breaking Down AdTech Silos: Leveraging Ad Context Protocol, Model Context Protocol, and User Context Protocol for Interoperable Agentic Advertising Workflows

The advertising industry is transitioning into an era of agentic media, underpinned by open standards - Ad Context Protocol (AdCP), Model Context Protocol (MCP), and User Context Protocol (UCP) - that enable AI agents to communicate and transact seamlessly across platforms. These protocols promise to reduce fragmentation, streamline integrations, and foster automation but face hurdles in adoption, governance, and security. AdCP orchestrates campaign-level agent interactions, MCP provides model-agnostic data connectivity, and UCP standardizes contextual signals for privacy-compliant targeting. Although these innovations offer significant benefits, such as operational efficiency, faster experimentation, and improved privacy alignment, their success hinges on broad industry adoption, robust governance, and clear demonstration of value. Technology buyers should proactively assess protocol compatibility, prioritize governance and compliance, and engage with standards bodies to shape the evolving agentic advertising landscape."As agentic media rises, will open standards have the potential to finally break the walled gardens or simply redraw the boundaries of power in advertising's AI drive. If they achieve critical mass, this could be game changing. - Roger Beharry Lall, research director, Advertising Technology and Agents, IDC
