Delete the local Microsoft token cache used by this Power BI MCP extension.
AI agents call powerbi_auth_logout to permanently remove resources in Power BI MCP for Claude — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting the token cache cannot be undone and removes the ability to authenticate until new credentials are acquired. While not data destruction in the traditional sense, it irreversibly removes a critical local resource (cached credentials). This is more severe than a Write operation because the deletion is not easily reversible.
From the tool's definition Tool description states 'Delete the local Microsoft token cache' — the verb 'Delete' combined with 'token cache' indicates irreversible removal of authentication credentials.
