Last updated: April 9, 2026

Claude Connectors wire Claude directly into the apps you already use — Gmail, Google Drive, Notion, Slack, HubSpot, and dozens more. After a one-time setup, Claude can read your emails, search your files, pull deal data, and take action inside those tools without you copy-pasting a single thing.

This guide walks you through the full setup, shows you which connectors to enable first, and gives you real prompts to put each connection to work immediately.

Key Takeaways

Here's what to know before you start:

• Claude Connectors give Claude real-time access to your external tools — no copy-pasting, no switching apps.
• Setup is a browser sign-in. You click Connect, approve the permissions inside a browser window, and Claude starts pulling data from your tools.
• Gmail, Calendar, and Drive work on the Free plan. Claude Pro at $20/month includes the full connector directory and unlimited custom connectors.
• MCP is the technology underneath, but you never interact with it directly. The setup screen handles everything.
• Gmail and Google Drive are the highest-impact first connectors for most small business owners.

Prerequisites

Setting up your first Claude Connector takes a Claude account and login credentials for the app you want to connect. Everything happens inside a browser — you click Connect, sign in to the app, approve the permissions, and you're done.

Before you start:

• A Claude account at claude.ai or the Claude Desktop app. Gmail, Google Calendar, and Google Drive connectors work on the Free plan. For the full connector directory and unlimited custom connectors, you'll want Pro ($20/month) or higher.
• Login credentials for the apps you want to connect (Gmail, Notion, etc.).

If you haven't set up Claude yet, start with the how to use Claude AI for your small business guide first.

What Are Claude Connectors?

Claude Connectors are integrations that give Claude direct access to the tools and data your business already runs on — Gmail, Google Drive, Notion, Slack, HubSpot, and dozens more. They let Claude read your data and take actions inside those apps from a single conversation.

Without Connectors, Claude only knows what you paste into the chat window. With Connectors, Claude can search your Gmail inbox, pull a file from Drive, check a deal in HubSpot, or read a Notion page — all without you lifting a finger beyond asking the question.

Think of Connectors as a universal plug that lets any app talk to Claude. Anthropic calls the underlying technology "USB-C for AI." You never touch the technical layer. The setup is a standard browser login screen — the same kind you see when you connect any app to Google.

Here is an overview of how Connectors work:

Connectors vs. Standard Claude Chat

Claude Connectors let Claude pull live data from your apps — Gmail, Drive, Notion, HubSpot — while standard chat only knows what you paste into the conversation window. The difference matters most for repetitive workflows where you're tired of copying and pasting the same information every session.

Connectors change that. Here's the practical difference:

The pattern is the same every time: instead of retrieving data manually and feeding it to Claude, you just ask. Claude retrieves it for you.

Step-by-Step: How to Set Up Your First Connector

Setting up a Claude Connector takes six steps. You'll open the Connectors menu in Claude settings, pick the app you want to connect, authorize the connection through a browser login screen, and test it with a real task.

Step 1: Open the Connectors menu

In Claude, click your profile icon in the lower-left corner and select Settings. In the left navigation panel, click Connectors. This opens the connector directory.

Step 2: Browse and pick a connector

Scroll the directory or use the search bar to find the app you want to connect. Start with the app you open first every morning. If your business runs on Google Workspace, Gmail or Drive is a good first pick. If you're in Microsoft 365, start with the Microsoft 365 connector. If your main system of record is a tool like HubSpot, Notion, or Slack, start there.

Step 3: Click Connect and authorize

Click the Connect button next to the connector. A browser window opens asking you to sign in to the app and approve the connection. Review the list of permissions Claude is requesting and click Allow. This is a standard OAuth login screen — the same kind you see any time you connect two apps together. You're approving access, not sharing your password.

Step 4: Review and adjust permissions

After connecting, click the connector name to see its active permissions. Read-only access is safer and sufficient for most tasks. If you only need Claude to reference information — not create, update, or delete — set the scope to read-only here. You can always come back later and expand the permissions once you trust how Claude is using the connector.

Step 5: Test it with a real task

Open a new Claude conversation and ask something that requires the connected tool. A few examples by category:

• Email (Gmail or Outlook): "What emails did I receive from clients today?"
• File storage (Google Drive, OneDrive, or SharePoint): "Find the proposal I saved last week."
• Workspace and notes (Notion): "What's in my meeting notes from last Monday?"
• CRM (HubSpot): "Which deals in my pipeline haven't had activity in the past 14 days?"

Step 6: Verify the connection is working

Go back to Settings > Connectors. The connector should show a green Connected status. If Claude answered your test question accurately and pulled real data, the setup is complete.

Here's the full flow end-to-end — connecting Gmail and Google Calendar, authorizing permissions, and running the first real prompts against live data:

Top Connectors for Small Business Owners

The best Claude Connectors for small business owners are Gmail, Google Calendar, Google Drive, Microsoft 365, HubSpot, Notion, and Slack — tools that cover email, scheduling, file storage, CRM, project management, and team communication. Not all connectors are equal. These are the ones I'd enable first, based on daily workflow impact.

Gmail + Google Calendar

Gmail and Google Calendar give Claude access to your inbox and schedule — the two places where most of your admin work lives.

If your morning starts with email triage and a calendar check, this combination collapses both into a single Claude question. Ask: "Summarize unread emails from my clients since yesterday. Flag anything urgent or time-sensitive." Then layer in scheduling context: "Do I have any conflicts this week?" or "Block 2 hours on Thursday for a proposal — what time works?" What used to take 45 minutes of clicking between Gmail and Calendar becomes one prompt before you've finished your first coffee.

Google Drive

Google Drive connects Claude to your stored documents — contracts, proposals, templates, client files — so you can ask questions about them without downloading or uploading anything.

Instead of hunting through folders before a client call or writing session, ask Claude directly: "Find the content brief for the Acme account and summarize the key messaging points." Claude surfaces it in seconds. The one catch: Drive search works best when your files have clear names. If your folders are a mess of "Final_v3_REAL.docx" files, Claude will struggle the same way you do. Clean naming pays off here.

Microsoft 365

Microsoft 365 gives Claude access to SharePoint, OneDrive, Outlook, and Teams — the four places most of the work lives inside a Microsoft-shop business. Available on every Claude plan. Read-only by design — Claude can search and reference content, but it cannot modify, delete, or create anything in your tenant.

Before your next client call or internal review, ask: "Find the Q4 strategic planning document in the Henderson SharePoint site and summarize the three biggest decisions." Then layer in Outlook: "Summarize email threads about the product launch from the past two weeks and flag anything still unresolved." Claude pulls both in seconds — where before, getting the same prep meant 40 minutes of tab-juggling across SharePoint, Outlook, and Teams.

One catch worth knowing up front: the Microsoft 365 connector only works with a work account tied to a Microsoft Entra tenant (any Microsoft Business plan). Personal @outlook.com, @hotmail.com, and @live.com addresses can't be used. If your Microsoft tenant has IT admin controls — which most business plans do — a Microsoft Entra Global Administrator has to grant consent once before anyone on the team can connect. If you don't know who your Global Admin is, that's the person to ask first.

Apollo

Apollo gives Claude access to your prospecting data — contact lists, company profiles, and outreach history. This one is most relevant if your business does outbound sales or lead generation.

If you're building targeted prospect lists, ask Claude directly: "Find me 20 VPs of Operations at SaaS companies with 50 to 200 employees in the Southeast. List their names, companies, and LinkedIn URLs." What used to take hours of manual research inside Apollo can run in a single Claude prompt.

HubSpot

HubSpot integration gives Claude read access to your CRM — contacts, deals, companies, and tickets — so you can analyze your pipeline without switching apps.

Run your weekly pipeline review without opening HubSpot once. Ask: "Which deals in my pipeline haven't had activity in more than 14 days? List them with the contact name and last activity date." Claude surfaces the stale deals in one response. Then ask a follow-up like: "What patterns do you see in the deals that closed won last month versus the ones that stalled?" Claude analyzes your pipeline without you exporting a single report.

One thing to know: the HubSpot connector is read-only. Claude can search, query, and analyze CRM data, but it cannot create or update records. You'll still log notes and move deals manually inside HubSpot.

Notion

Notion integration connects Claude to your Notion workspace — search across pages, pull in context, and create new pages directly from a conversation.

Before a client call or internal sync, ask: "Find the campaign brief for the Henderson account in Notion and give me a 5-bullet summary of the key deliverables and deadlines." It takes under 30 seconds. After the call, follow up with: "Create a new Notion page called 'Henderson Q2 Recap' with sections for decisions made, action items, and next steps." Because the Notion connector supports both read and write, the prep and the follow-up live in the same Claude conversation.

Slack

Slack integration lets Claude draft, schedule, and send messages in Slack — and read threads for context — without leaving a Claude conversation.

Use it to draft company updates without opening Slack first: "Draft a message for #team-all announcing the Q2 product launch. Keep it under 5 sentences and keep the tone casual." Claude writes the draft inside your conversation, and you can refine it with follow-ups before sending.

The Slack connector also handles scheduling. Ask: "Schedule a message to #marketing for tomorrow at 9am about the product launch." One caveat: once a message is scheduled, editing or rescheduling it is handled inside Slack's native Drafts and Sent view, not through Claude.

How to Find and Add Third-Party Connectors

Claude's Connectors directory grows regularly as third-party developers publish new integrations. The directory inside Claude settings is the main place to browse, and I'll update this guide as notable new connectors become available. Connectors are organized by category — Communication, Productivity, CRM, Project Management, and more. Use the search bar if you already know the app name.

New connectors are added regularly by third-party developers, not just Anthropic. If you don't see a specific tool, check the connector's website or support docs — some publishers announce MCP support before it appears in Claude's built-in directory.

What to Connect (and What to Leave Out)

Not every app in your stack needs to be connected to Claude. I recommend starting with 2 or 3 connectors that cover your daily workflow rather than connecting everything at once. More connections aren't always better — each one is a permission you're granting, and an unnecessary connection adds noise without adding value.

Good candidates for connecting:

• Apps you open every day — Gmail, Calendar, Drive
• Apps where you frequently need to retrieve specific information — Notion, Slack, HubSpot
• Apps with repetitive lookup tasks you'd rather automate — CRMs, project management tools
• Apps where you need Claude to take action, not just read — sending emails, updating records, adding notes

Leave these out, at least to start:

• Apps with highly sensitive data and no strong business case for Claude access (payroll, HR records)
• Apps you rarely use — connecting them adds setup time with no payoff
• Multiple connectors for the same category — you don't need both HubSpot and Salesforce connected if you only actively use one

Testing and Troubleshooting

If Claude isn't pulling data from a connected app, the fix is almost always in the connection settings rather than in Claude itself. Most issues come down to expired authorization, insufficient permissions, or a connector that silently disconnected. Here are the most common causes and fixes:

• Claude says it can't access the app: Go to Settings > Connectors and confirm the connector shows a green Connected status. If it's disconnected, click it and re-authorize. This is the fix I've used most often — a connector silently disconnects after a password change or session timeout.
• Claude pulls outdated information: Connectors retrieve live data, but some apps have short caching windows. Wait a few minutes and ask again. If the issue persists, disconnect and reconnect the connector.
• Permission error during setup: You may not have admin access to the app you're trying to connect. Check with whoever manages the account — Google Workspace admins can restrict third-party OAuth apps.
• Connector doesn't appear in the directory: The app may not have published MCP support yet. Check the app's official documentation or support pages for MCP or Claude connector announcements.
• Claude reads data but can't write to the app: You likely authorized read-only permissions during setup. Go to Settings > Connectors, disconnect the connector, reconnect it, and select broader permissions when the authorization screen appears.

If none of these fixes work, Anthropic's support center at support.anthropic.com has connector-specific troubleshooting guides.

Frequently Asked Questions

These are the questions I hear most often from small business owners setting up their first Claude Connectors. Every answer below is based on how Connectors work as of April 2026.

What are Claude Connectors?

Claude Connectors are integrations that give Claude access to the apps you already use — Gmail, Google Drive, Notion, Slack, HubSpot, and more. Once connected, Claude can read your data and take actions inside those apps directly from a conversation, without you needing to copy and paste anything. Setup uses a standard browser authorization flow.

Are Claude Connectors free?

Partly. Gmail, Google Calendar, and Google Drive connectors are available on every plan, including Free. Free users can also add one custom connector via remote MCP. The rest of the built-in directory, unlimited custom connectors, and advanced features like Google Drive Cataloging (indexing Drive with RAG) require a paid plan. Claude Pro at $20/month unlocks the full directory. Team and Enterprise plans add organization-level admin controls — on those plans, an Owner or Primary Owner enables connectors before individual users can authenticate.

Can Claude write to my apps or only read from them?

It depends on the connector. Some are read-only by design — Microsoft 365 and HubSpot only let Claude search and analyze, not modify records. Others — like Gmail, Notion, and Slack — support both reading and writing if you grant those permissions during setup. You control the scope at the time of connection and can adjust it later from Settings > Connectors.

Is my data safe when I connect apps to Claude?

Connectors use the same secure login flow you see when connecting any app to Google or Slack. Claude only accesses what you explicitly authorize — nothing more. You can revoke any connector's access at any time from Settings > Connectors. For details on how Anthropic handles your data, see Anthropic's privacy policy.

What is MCP and do I need to understand it?

MCP stands for Model Context Protocol — the technical standard that powers Connectors. Think of it as a universal plug that lets any app talk to Claude in a standardized way. The setup process happens entirely inside a browser screen, and Claude handles the rest behind the scenes.

Next Steps

Pick one connector from this guide, set it up this week, and actually use it on a real task. One working connection is worth more than a dozen you might enable later.

Once you have Connectors running, the natural next move is Claude Projects — persistent context about your business, your clients, and your standards that every conversation starts with. For the full walkthrough, see How to Set Up Claude Projects for Your Small Business.
