Your product has a new user. It’s not human.

Summary

The traditional definition of an Ideal Customer Profile (ICP), which assumes a human user, is becoming obsolete. This foundational assumption is breaking as AI agents increasingly interact with products on behalf of humans, often utilizing protocols such as the Model Context Protocol (MCP). Historically, even API-first products targeted human developers who chose and integrated solutions. However, Large Language Models (LLMs) are now poised to become involved in, or even replace, every step of this interaction process. This shift necessitates a fundamental re-evaluation of what constitutes a "user" for any product, moving beyond the human-centric view that has long underpinned product development and marketing strategies.

Key takeaway

For AI Product Managers defining future product strategies, you must critically re-evaluate your Ideal Customer Profile. The traditional assumption of a human user is rapidly breaking as AI agents, often powered by LLMs, begin to interact directly with products via protocols like MCP. Your team should proactively investigate how agents might become primary users, influencing product design, integration, and value proposition, rather than solely focusing on human-centric engagement models.
