AI agents use outlook_create_draft to create or update resources in Mcp Windows — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Windows environment.
This tool creates a new email draft, which is a reversible write operation. The draft is not automatically sent, so it does not execute external communications or trigger financial/destructive actions. However, it has medium severity because an AI agent could draft misleading or harmful emails that, if sent, could enable phishing, impersonation, or social engineering attacks.
From the tool's definition Tool name 'outlook_create_draft' and description 'Create a new email draft in Outlook' indicate data creation without sending or executing external operations.
