Get the current user\
AI agents call teams_get_me to retrieve information from Teams MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the authenticated user—a simple query operation with no modification, deletion, or execution of external commands. It has minimal blast radius if misused by an AI agent, as it only exposes the identity of the current user without enabling further actions on its own.
From the tool's definition Tool name is 'teams_get_me' with description 'Get the current user'. The verb 'Get' and the action of retrieving user identity information are characteristic of Read operations that query data without side effects.
