Google Workspace OAuth (Gmail / Drive / Docs / Sheets / Calendar)

This lets Claude read and write your Google Workspace stuff. Takes 5-10 minutes the first time. Free.

Steps

1. Open https://console.cloud.google.com in your browser.
2. Sign in with the Google account you want Claude to access.
   Use the email you actually use day-to-day.
3. At the top, click the project dropdown. If you have no projects, click New Project.
   Name it "nello-claw". Leave organisation as default.
4. Wait for the project to create. Switch to it via the dropdown.
5. In the search bar at top, type "APIs and Services". Click Library.
6. Search for and enable each: Gmail API, Google Drive API, Google Docs API, Google Sheets API, Google Calendar API.
   Click each one, then Enable. One at a time.
7. Now in the search bar type "OAuth consent screen". Click it.
8. Pick External. Click Create.
9. Fill in: app name "nello-claw", user support email = your email, developer contact = your email. Save.
10. Skip Scopes screen by clicking Save and Continue.
11. On Test Users page, add your own email. This lets you test without publishing.
12. Back in search, type "Credentials". Click it.
13. Click Create Credentials → OAuth client ID.
14. Pick Desktop app as the application type. Name it "nello-claw". Click Create.
15. Google shows a dialog with Client ID and Client Secret. Copy both.
    → paste into GOOGLE_OAUTH_CLIENT_ID + GOOGLE_OAUTH_CLIENT_SECRET
16. Paste into the wizard fields. Also enter the email you signed in with.

If something goes wrong

• API enable button is greyed out — Make sure you switched to the right project at the top.
• OAuth consent screen says "verification required" — Pick External, mark as Testing, add yourself as a Test User. You do not need to publish.
• On first MCP run a browser opens asking for consent — That is expected. Click your account, allow access. Token caches after first time.
