How to Use Copilot Studio’s “Add Tool” Feature with SharePoint – Add Attachment

👋 Introduction

Copilot Studio is fast becoming a go-to platform for building intelligent, conversational agents across Microsoft 365 and Power Platform. One of the most underrated – but super useful – features in Copilot Studio is the “Add a Tool” option.

Now, many of us think we always need to write a Power Automate flow or an API to get business logic into our Copilot. But guess what? You can actually use out-of-the-box tools like the SharePoint connector, without writing a single line of code or designing a custom flow!

In this blog, I’ll walk you through how to use the built-in SharePoint connector via the Add Tool section to let users add attachments to SharePoint list items – directly from the Copilot conversation.

Let’s get started 🎯

🛠️ What is the “Add Tool” Feature in Copilot Studio?

The “Add Tool” section is where you bring in external actions that Copilot can perform.

In simple terms:

You’re giving your Copilot new skills – like uploading a file, fetching data, or submitting a record.

What’s great is – Copilot Studio already has built-in access to Microsoft Dataverse, SharePoint, Teams, Outlook, Planner, and many other connectors. So instead of building your own flows, you can simply search and plug them in.

🧩 Scenario – Add Attachment to a SharePoint List Item

Let’s say you're building a Copilot for your internal HR team. One of the use cases is to upload employee documents (like resumes or ID proof) to a SharePoint list.

Here’s how you can do this without writing any flow – just using the SharePoint connector inside Copilot Studio's "Add Tool".
