WHAT IT DOES

What outlook_flag_message does on Sage MCP

AI agents use outlook_flag_message to create or update resources in Sage MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.

RISK

Why outlook_flag_message is rated Medium

This tool modifies message metadata (flag status) in Outlook, which is a reversible write operation. It does not delete data, execute code, or involve financial transactions. The action can be undone by unflagging, making it a Write category. Medium severity because misuse could affect email organization and task tracking for potentially many messages across a multi-tenant platform.

From the tool's definition Flag, unflag, or mark a message as complete. Flagged messages appear in the flagged email view.
