Short answer

Ad Context Protocol (AdCP) is an open standard, launched in October 2025 and built on the Model Context Protocol (MCP), that gives AI agents a common language for advertising. It lets buyer and seller agents discover inventory, plan, buy, and report on media across platforms. AdCP aims to reduce custom integrations in agent-driven media buying.
