Logout from Willys and clear authentication session
AI agents call mcp__willys_logout to permanently remove resources in Willys MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Logging out clears the authentication session, which is an irreversible action in the moment — the session is destroyed and cannot be restored (only a new login can create a new session). This disrupts the agent's ability to perform further authenticated operations. While not as severe as deleting data, session destruction is non-reversible without user re-authentication, placing it in the Destructive category.
