Using `Power Automate` Webhooks as an MCP Bridge for Microsoft 365

Power Automate can turn existing M365 permissions into callable agent tools without Graph admin approval. Useful for personal ops automation, but webhook hygiene is the real risk.

[ KEY POINTS ]
  1. Each M365 action becomes one Power Automate flow with an HTTP trigger, then a small FastMCP server exposes it as a Claude tool.
  2. The setup covered 22 flows: email, calendar, OneDrive notes, Planner tasks, Excel rows, and Word templates.
  3. Signed webhook URLs act like passwords. A duplicated URL already caused the wrong action to run, so config review matters more than code size.
