logout · SharePoint MCP Server MCP: Risk & Policy

WHAT IT DOES

What logout does on SharePoint MCP Server

AI agents call logout as a supporting operation in SharePoint MCP Server workflows.

WHY IT NEEDS A POLICY

Why logout needs a policy

This tool clears authentication tokens and ends the session. It does not read, write, execute, destroy data, or move money. It is an auth/session management operation — the closest fit is 'Other' since it only affects the local credential/token state, not any SharePoint data or external systems.
