Workspace CLI

What it does

Workspace CLI is a high-performance, Rust-based tool that connects AI agents to the entire Google Workspace ecosystem. It provides a deterministic, speed-optimized interface to Gmail, Drive, Calendar, Docs, Sheets, Slides, Chat, Contacts, and Tasks, converting complex API responses into token-efficient formats like TOON and JSON.

Tools

The server exposes approximately 50 tools including:

• Gmail: gmail_list, gmail_send, gmail_reply, gmail_modify (labels/read-state)
• Drive: drive_list, drive_upload, drive_mkdir, drive_share, drive_permissions
• Calendar: calendar_list, calendar_create, calendar_update, calendar_delete
• Docs/Sheets/Slides: Full CRUD operations, including Markdown extraction for Docs and range updates for Sheets.
• Chat/Tasks/Contacts: Space management, message sending, and contact directory search.
