Claude Connectors Tutorial: Link Gmail, Calendar, Notion (and 9,000+ via Zapier)

Key Takeaways

• Where to add them: in Claude, click Customize → Connectors → + → Browse connectors. There are 200+ services (Canva, Microsoft 365, Figma, Notion, Gmail, Google Drive, and more).
• Connect Gmail: click the service, continue, then grant permissions (or "Select all") via the OAuth screen. The connector then appears in your list.
• Read vs. write by default: Claude gets read-only tools out of the box (search inbox, summarize threads). Any action that modifies your account — like creating a draft — requires your approval first. You can change these per-connector later.
• It triages, not just lists: asked to flag high-priority email, Claude surfaces the one message that needs attention and explains why, instead of dumping every unread item — then can draft a reply straight into Gmail for review.
• Zapier MCP for everything else: when an app has no built-in connector — or you want Claude to take stronger actions like sending the email — connect the Zapier MCP server (works on Zapier's free plan). It opens access to 9,000+ apps with far more actions, and you can pick exactly which actions Claude may use.
• Auditability: Zapier keeps a history of every action Claude took through your connected apps, so you can review what it actually did.
