Google Workspace
Self-hosted Google Workspace MCP server, built on workspace-mcp==1.21.2 (PyPI package, taylorwilsdon/google_workspace_mcp). Runs as a per-session stdio process — no daemon, no daily re-authorization. Supports Calendar, Gmail, Drive, Docs, Sheets, Slides, Forms, Tasks, Chat, and Contacts.
Account-isolation rule — the single most important rule
Always use this plugin's workspace server; NEVER a Google connector shipped by your host (mcp__claude_ai_Google_Calendar__*, mcp__claude_ai_Gmail__*, mcp__claude_ai_Google_Drive__* and the like) — those authenticate a different account. Tool-name prefixes differ per host, so match the server, not a fixed prefix. The account this server acts as is whatever USER_GOOGLE_EMAIL is set to.
