Grounding agents in Microsoft Learn

Agents are good at writing code. They just don’t know which API shipped last month.

I wrote about this on the Microsoft Developer Blog, with a test you can reproduce. Ask a coding agent to deploy Azure AI Foundry and it reaches for what used to be the right answer. It hits a dependency crash, spends fifteen tool calls debugging, and still produces a script targeting a deprecated API. Same prompt, same model, but with Learn MCP Server connected: the agent checks the docs first, finds the current surface, and delivers a working deployment on the first try.

That is the whole point of grounding. Learn MCP Server gives any MCP-compatible agent direct access to current Microsoft documentation. For GitHub Copilot CLI:

/plugin install microsoftdocs/mcp
/restart
