Connect VS Code (Copilot) to Microsoft 365

One line gives VS Code (Copilot) your Microsoft 365 account as tools: 20 endpoints, mail, events, teams, called with your own connection. No key in the prompt, a receipt for every call, revoke VS Code (Copilot)'s access alone any time.

Get the line for VS Code (Copilot)Connect Microsoft 365 first

Three steps

  1. Create a free 0n3 account and connect Microsoft 365. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into VS Code (Copilot). One-click install link, or .vscode/mcp.json.
  3. Ask VS Code (Copilot): whoami. Then: "Send a mail in Microsoft 365".
One-click install

Install

The line above carries a placeholder; 0n3.app/install mints a real key named for VS Code (Copilot) and fills it in.
