Cisco IQ: Engineering APIs for the Agentic Era

From day one, Cisco IQ was built on a clear mandate: deliver unified, deterministic, AI-powered operational intelligence through an API-first architecture. We delivered on that promise with the announcements last week at Partner Summit 2026. We officially opened Cisco IQ with a comprehensive suite of production REST APIs and our Model Context Protocol (MCP) server. This ensures our intelligence runs seamlessly with any existing system or AI agent. The best part, the foundation extends to our partners as well. Partners can now enhance their own managed services with capabilities from Cisco IQ, integrated through API and MCP interfaces. Since Cisco IQ’s general availability in Apr 2026, over 16,000 customers have deployed Cisco IQ, and, as we expand this ecosystem, a new class of API consumer has arrived at scale: the autonomous AI agent. Agents do not consume APIs the way human software developers do. Developers read specifications, plan integration loops, and write deterministic code. AI agents explore probabilistically: they guess, they retry, and they attempt to join disparate data within their prompt context window. So, we asked a fundamental engineering question: what does an API architecture look like if it is designed to serve human developers and autonomous AI agents…
