Claude Connectors.

How to connect Claude to your apps:

I mostly open Claude now.

Because my Claude is connected to everything else: my Gmail (email), my Slack (team channels), my Granola (meeting notes). It’s called Claude Connectors.

On Claude, click on the + and find Connectors

Claude has over 200 connectors. But you’re probably using none of them, and this newsletter is here to help you get started.

Two things before we start:

1. Save this guide for later. Book a 15 min meeting this week to act on it.

2. Share it with your team who wants to get more from Claude.

PS: This newsletter mostly grows from your shares. 1,000+ shares per article is my weekly north star. It keeps the article free & helps me stay laser focused on mastering AI for you.

I - How to connect your app to Claude.

A Connector is a 1-click bridge between Claude and an app you already pay for.

Here’s how to connect your app to Claude:

1. Open Claude. Go to the plus “+” inside the chatbox.

2. Find “Connectors” and click on “Add connector”. Add one of them.

3. Now open a new chat. Click “+” in the chat bar > Connectors > make sure your app is toggled on for that conversation. It should be automatic.

Step 1: Find the + inside the chatbox.

Step 2: Go to Connector → Add connector.

Step 3: Search for a connector (like Gmail, Gamma, Google Drive, Granola...)

Step 4: Test it by simply naming the connector (like Granola here).

What changes when you turn one on?

Let’s see some examples:

• Gmail on: ask “what’s pending in my Gmail inbox from this week?” and Claude answers from your actual Gmail. 0 copy-pastes.

Claude made as many drafts as I have unread emails.

• Granola on: ask “I need a summary of all of last week’s meeting transcripts,” and Claude reads them all. 0 dashboards opened.

And you can combine the connectors: Granola + Gmail + Slack…

• Slack on: ask “extract this entire thread and give me the action items,” and Claude pulls the entire context. 0 tabs visited.

Claude has the entire context of my Slack, and asks me questions before proceeding.

I do all of the work inside Claude, with context. And it’s live on my apps.

PS: 3,500 people pay for my Substack to get access to me in a Slack channel. But the Slack got messy. So I am migrating to Circle instead. If you are a paid subscriber to this newsletter, hit me up by DM! I’ll send an invite to my Circle.

II - My 9 favorite Claude connectors.

Now here are my 9 favorite Claude Connectors I (actually) use every week.

1. Granola. For my meeting transcripts.

Granola is my notetaker. I think it’s the simplest/most complete one out there.

When I join a meeting (on Zoom, Teams, Meet), Granola automatically captures the entire transcript and stores it on my computer inside its app.

This is a typical prompt I use inside Claude, with Granola:

Pull my last meeting from Granola. Summarize in 5 bullets.
Then list every action item assigned to me, with deadlines.
Then flag the 2-5 blockers I might have to complete some items.

This is definitely one of those “wow” moments of AI.

Pro tip: Combine Granola’s context with everything else. For example, when I’m negotiating a contract, I ask Claude to read Granola+Slack+Gmail. Combine the connectors together!

2. HubSpot/Salesforce. For lead generation.

Most people use HubSpot or Salesforce to manage their leads (in a CRM).

Prompt I use inside Claude:

Read my HubSpot pipeline.
List every deal in stage "Proposal Sent" that hasn't moved in 7+ days.
For each: write a follow-up email I can send today.
Tone: direct, French-blunt-warm. No "just checking in."

You don’t have to open your HubSpot to read your HubSpot.

Pro tip: Stop using HubSpot/Salesforce only as a CRM. Use it as a research input. Ask Claude, “Based on my last 5 closed-won deals, what’s the common thread?”

4. Notion. For my team’s knowledge base.

I use Notion for our content calendars and knowledge base. Like, for example, my social media posts, all of our standard procedures on how we do things…

Prompt I use with Notion:

Go to Notion, NEW Post Calendar. Extract the content from May 12, 2026 (Design brief, Caption). Create 2 new ones using the same ideas and techniques.

The point is not to use AI to outsource your thinking, but instead to have access to unlimited ideas to choose from.

Worth noticing, I am a small company, but most big ones use Microsoft or Atlassian with Jira, Confluence... Needless to say, Claude can connect to all of them. But I haven’t tried. So go & do it and let me know if it’s good :)

5. Microsoft 365. Because you probably have to use it.

One toggle. 4 apps: Teams, Outlook, Calendar, OneDrive.

Yes, Claude is better than Copilot. No questions asked.

I consult SME businesses in the US, generating at least $100 million per year. I think most, if not all, of them were using Microsoft. You’re probably one of them.

This is a typical prompt to call the entire Microsoft suite:

Read my Outlook + Calendar for next Monday.
List every meeting where I have no prep notes yet.
For each: pull the relevant Teams thread or OneDrive doc.
Output a 1-page brief per meeting.

Pro tip: It works even better when the entire company adopts it. Because then people adopt new ways of collaborating/communicating. They know AI can use it, so they start being clearer everywhere. This is the new way of working.

6. Slack. Because I don’t use Microsoft Teams.

I use Slack, not Teams, to talk with my teams.

A typical prompt I use :

Read #tathastu, #team-lead, #gpc-consulting, #circle-studio from the last 48 hours. Surface the 3 things I need to react to. Skip jokes, GIFs, standup updates.

You know that thread that is impossible to find. Well now, Claude knows all of them.

7. Google Drive. Because I know we all use Google Drive.

I use Google Docs & Google Sheets heavily. So I have to connect Claude to my Drive. But the way I use it with Claude here is a little different.

1. I go to Claude Cowork. And I explain the spreadsheets I want.

2. Cowork builds it. And I keep refining it with follow-up prompts.

3. Then eventually, I click on the “Google Drive” button to open a new tab.

4. Now all of Claude’s work is on my Google Drive (= Google Sheets here).

Step 1: Go to Claude Cowork. Ask for a spreadsheet about [X]. Bonus point if you uploaded files before for better context.

Step 2: After enough iterations with Claude, you get the right spreadsheet, and you can click on the Google Drive button.

Step 3: It opens up a Google Sheets, populated, instantly.

8. Gamma. To make on-brand slides in seconds.

I use Gamma for all of my slides. It’s the fastest/cheapest/easiest. Hard to beat.

A typical Gamma prompt:

Go to Gamma. Create a [NUMBER]-slide deck on [TOPIC] for [AUDIENCE].
Goal: [What you want them to do or understand].
Cover: [List 5-8 key points or sections].
Tone: [confident / data-driven / concise].
Make it visual, clean, and one idea per slide.

You can see Claude calling the Gamma tool with its connector.

The deck is ready in Claude, and I can further edit it inside Gamma.

9. Gmail. The most obvious win.

I save the most known for last.

What it replaces: searching your inbox, finding the wrong email, searching again.

It also works for Outlook emails, obviously. A prompt you’d like to try:

Read my Gmail from this week.
Group every email into 3 buckets:
1. Needs my reply today.
2. Can wait until Friday.
3. Newsletter / FYI / can ignore.
Output: 3 lists. No commentary.

Non-obvious tip: ask Claude to draft the replies as drafts in Gmail, not in the chat. Just add the prompt: “Save the 5 replies as drafts in my Gmail.”

If you only turn on 3 connectors today, pick Granola, Gmail/Outlook, and Slack/Teams (depending on what you use internally). This trio compounds.

III. The entire list of Claude Connectors.

The directory is 200+ Connectors and growing.

Find all of the connectors here: https://claude.com/connectors#connectors.

If you want to find all of them directly inside your Claude, do this:

Click on Manage connectors after finding Connectors.

Then click on the + and Browse connectors.

You have the entire list of Claude Connectors.

IV. When NOT to use a Connector.

3 rules.

1. Don’t leave them all on by default.

Connectors burn tokens before you type. Every Connector loaded is context Claude has to scan.

Turn them on per chat. Off per chat. Treat the toggle bar like a kitchen tap.

If you need more tips on avoiding wasting Claude’s tokens, click here.

2. Don’t use Connectors for creative work.

When you’re drafting a LinkedIn post or writing a script, you want a clean room.

Slack noise, Gmail noise, Notion noise pollutes the output. My default writing chat: every Connector off. Always.

3. Don’t grant write access until you trust the read flow.

Read-only first. Watch how Claude uses it for a week.

Then grant write. Most data accidents happen on day one when someone enables a Connector with full write access and asks Claude to “clean up my Drive.”

V. Build your own connector (for devs).

This section is very technical. 99% of you don’t need it. So skip it.

A Connector is just an MCP server with a public URL.

You won’t create one. But your tech team could!

Or ask me to do it for you :) I have a consulting firm in NYC.

You can ship one in maybe 3-4 hours if you’ve never touched code. 15 minutes if you have. You’ll need:

• A Claude Pro, Team, or Enterprise plan (custom Connectors aren’t on Free).

• The app’s API, from Anthropic.

• A Cloudflare Workers account. Free tier covers 100,000 requests a day.

Step 1. Open Claude Code and paste this prompt:

Build me an MCP server in Python using FastMCP.
One tool: get_<thing>(args).
Use Streamable HTTP transport.
Deploy target: Cloudflare Workers.

Output:
1. The full server code.
2. The deploy command.
3. The URL pattern I'll paste into Claude Settings.

Replace <thing> with the action you want. (”get_latest_email_from_sender”, “get_open_deals_above_amount”, “get_revenue_for_month”.)

Step 2. Run the deploy command Claude gave you.

You’ll get a public URL ending in your-server.workers.dev/mcp.

The /mcp path is required.

Step 3. Add it to Claude.

Settings > Connectors > Customize > Add custom connector.

Add the URL here.

Paste the URL with /mcp at the end. Name it. Save.

Open a new chat. Toggle the Connector on. Test the tool.

3 things that break the first time:

• Forgetting /mcp in the URL.

• Cold-start timeout on free tier hosts. (Cloudflare Workers > Vercel for this. Vercel times out faster.)

• CORS headers blocking the call.

Wrap your own internal tool. Your private database. Your team wiki. The spreadsheet you’ve kept for 3 years. The Connector is a permission layer between Claude and any system you control.

Where to start.

You won’t turn on all 9 tonight. Don’t try.

Pick 3.

My favorite stack of connectors is:

1. My notetaker of meetings (mine is Granola).

2. My email (mine is Gmail).

3. My team channel (mine is Slack).

They give the needed context to Claude so I can do better work.

It’s obvious, but I’ll say it again.

I don’t care about Claude, or any other AI model.

I don’t pick sides. I’m not paid to make this newsletter.

I’m sharing, twice a week, how my work is changing (very fast) with AI.

As I’m trying to keep up, I want you to keep up.

Remember how I have been begging you to switch to Claude in January, so you stay ahead. Well, I will continue to do so for any future upgrades.

Because I want to be the greatest filter to the AI noise. And 500,000+ people trust me to be their filter. Some came because of my LinkedIn. But most readers subscribed because someone they trusted sent them one of my articles.

If this article helped you, be that person for someone else (and share it):

Sharing does not cost you anything. And it supports my work & your team!
