What it does
Bridges Claude and other AI assistants to Google Workspace, exposing full APIs for Gmail, Drive, Calendar, Docs, Sheets, Slides, Forms, Chat, Tasks, Contacts, and Apps Script. Enables fine-grained operations: compose and send emails with attachments, create and edit spreadsheets cell-by-cell, manage events with advanced scheduling, search files, share documents, and orchestrate cross-app workflows via Apps Script. Supports both free Google accounts and enterprise Workspace plans with OAuth 2.0/2.1 authentication, stateless mode for containerized deployments, and external OAuth provider integration for centralized multi-user hosting.
Who it's for
Product managers and ops teams automating workflows across Gmail, Sheets, and Drive. Backend engineers building data pipelines or onboarding automation. Enterprise teams that want Claude to manipulate Workspace on behalf of their users without credential sharing.
Common use cases
- Fetch unread emails, summarize threads, and draft replies with context from linked Drive files.
- Query a Sheets model for parameters, then send batch Gmail campaigns based on the results.
- Create and format a Docs proposal, schedule a Calendar meeting, and send invites.
- Aggregate insights from Forms responses and auto-escalate flagged entries to a Sheets tracker.
- Orchestrate multi-service workflows (create a folder, upload a file, share it, email the link) via Apps Script.
Setup pitfalls
- OAuth 2.1 requires a Google Cloud project with correctly configured redirect URIs; mismatches between http/https or localhost/domain are the most common blockers.
- The server reads and writes files directly—verify filesystem permissions and, if deployed, enforce bearer-token validation at reverse-proxy boundaries.
- High risk classification due to Workspace API scope; restrict access to trusted users, never hardcode credentials, and use stateless mode with external OAuth for multi-user deployments.
