Agents are becoming increasingly important tools for end-users to interact with digital services, and businesses must provide a good agent experience (AX) by supporting agents and the emerging standard Model Context Protocol (MCP). The MCP is an open standard designed to unify how agents receive context and interact with digital services. It provides a universal remote control for AI assistants, enabling them to fetch databases, manipulate designs, or control music apps through a standardized interface. By adopting MCP, businesses can empower agents to act decisively and creatively on behalf of users, leading to exceptional Agent Experience (AX). The key principles of AX include human centricity, agent accessibility, contextual alignment, agent interactivity patterns, and differentiating agent interaction. These principles are established by the community-driven specification for giving agents context and access to interact with digital services. By unifying context packaging, tool discovery, and bi-directional interaction, MCP greatly reduces integration complexity and accelerates the development of sophisticated agent experiences.
