Full transcript (original language)

00:00 In this video, I’ll show you how to connect two Gmail accounts to Claude at once using Compose EO. So, you can search, summarize, or draft across either inbox without any of that back and forth. Compose EO is a tool that allows you to connect any AI, including Claude, to over 1,500 apps. Think of it like giving your AI hands. Here’s what you need before we start. A free Compose EO account, the two Gmail accounts you want to connect, and Claude. This works with Claude.ai, Claude desktop, Claude code, or Claude

00:32 co-work. So, let’s get started. First, head to compose.dev and create a free account. No credit card needed. And you get a generous free tier of tool calls per month. Once you are in, you will land on the Compose EO dashboard. From the dashboard, towards the left-hand side, click on connect apps. And find Gmail in the toolkit list. Click connect. Now, this kicks off a standard Google login screen. You’ll be

01:05 redirected to sign in and grant permission. And that’s our first account connected. I’ll label this one as work Gmail, so it’s easy to tell apart later. Now, here’s the part most tools, including Claude’s own built-in Gmail connector, don’t let you do. Claude only lets you connect one Gmail account at a time, but in Compose EO, connecting a second account is just as easy as the first. Click connect on Gmail again, and sign in with your secondary or second

01:39 account instead. I’ll label this one as secondary Gmail. Now, Compose EO has two separate, fully authenticated Gmail connections sitting under my account. Completely isolated from each other, but both available to use. Next, we need to link Compose your to Claude. In the dashboard, grab the Compose your MCP URL. It looks something like this. Now, copy that as we’ll need it in the

02:12 next step. Now, switch over to Claude. Here, click on customize towards the left right here, and click on connectors. And finally, click on add. Give it a name. I’ll just call it Compose your and paste in the MCP URL you just copied a moment ago. Keep the settings as they are and click add. And Claude will prompt you to authorize the connection. Approve the access in the browser window that pops up, and you’re done. Claude now has a live connection to

02:43 Compose your and through it to both Gmail accounts that we just set it up. Let’s put it to work. I’ll just ask a few different things to show how this plays out in practice. As you can see, Claude got the information directly from the second account. No switching tabs. Now, let’s try with the work account. I’ll just ask Claude to pull up something from one of my orders that I placed like few months ago. And then, you can even ask it to send a reply or any other messages you would like. This

03:17 is honestly my favorite part of this whole setup. If you have used Claude’s built-in Gmail connector before, you already know it can write you a draft, but that’s as far as it goes. You still have to hop into Gmail and hit send yourself. With Compose your connected, Claude can actually send the email for you right from the chat. No extra step to switching over to Gmail to finish the job. And that’s it. Two Gmail accounts, one Claude assistant, no more switching tabs to find what you need. And it

03:51 doesn’t stop at two. With Compose your you can connect an unlimited number of Gmail accounts for free. Plus tools like Slack or Notion using the same setup. Thanks for watching and I’ll see you in the next one. Take care.
