Designing Product Simplicity for the Agentic AI Era
Microsoft is unifying its CoreAI portals by releasing its design system guidance via both Figma libraries and experimental MCP servers for AI agents.
What: Microsoft is addressing UI inconsistency in its CoreAI tools by deploying a shared design system that feeds guidance to human designers via Figma and to coding agents via Model Context Protocol (MCP) servers.
Why it matters: This signals a shift where design systems must function as APIs for AI-driven development rather than just static references for human developers.
Decoder
- MCP (Model Context Protocol): An open standard designed to let AI models connect to external data sources, tools, and design specifications.
- Fluent 2: Microsoft’s current design system language used across their software products.

Microsoft's CoreAI portals all sat on Fluent 2 and still felt disjointed, because shared components did not prevent teams from inventing different navigation, layouts, and flows. The CoreAI Design System, forked from Foundry's work, ships guidance through both a Figma library and an experimental MCP server so coding agents can consume it too.
