# Connectors overview

> Connect your mail, calendar, chat, files and other apps so Dvina can read them, and approve every action that changes something.

Connectors link Dvina to the apps you already use, like your mail, calendar, team chat, files, CRM and payments. Once an app is connected, Dvina reads it to answer your questions and notices when something changes.

## What connectors do

More than 100 apps can be connected, and each one uses your own sign-in. After you connect an app:

- **Dvina answers from it.** Ask once, and Dvina looks across your apps for one answer.
- **Dvina can act in it.** It can draft, create and update things for you, and it asks first.
- **Dvina notices changes.** When something changes in the app, you get one short card that says why it matters. See [Proactive and Feed](/docs/use-dvina/features/proactive).

## Connect an app

1. Open Settings and choose **Apps**.
2. Choose **Browse Apps…**, then find the app you want. You can search by name.
3. Choose **Connect**.
4. Sign in to the app with your own account and allow access.

When the app is connected, Dvina tells you, and it appears under **Connected** in Settings › **Apps** and in **Apps** in your Library.

You can also connect apps during setup, or from your Feed with **Connect an app**.

### Connect more than one account

You can connect your work and personal accounts of the same app.

1. Go to Settings › **Apps** and choose the app.
2. Under **Accounts**, choose **Add Account…** and sign in with the other account.
3. To tell them apart, choose **Rename** and give each a name, like Work. Choose **Make Default** for the one Dvina should use first.

When Dvina reads, it reads all of your accounts. When it writes, the approval card shows which account it uses.

## Reading and writing

Dvina reads your connected apps freely, so it can answer and prepare work for you. Anything that changes something asks for your approval first. The approval card shows what Dvina wants to do, and you choose **Allow** or **Reject**.

For some actions, you can choose **Always allow in this chat**. Sending something to another person, deleting for good and paying always ask, every time, whatever you allowed before.

> [!IMPORTANT]
> Nothing goes to another person, is deleted for good or gets paid until you choose **Allow**.

Databases and warehouses you connect are read-only. Every query is checked to be a single read before it runs. See [Databases and warehouses](/docs/connectors/databases).

## Disconnect an app

1. Open **Apps** in your Library and choose the app.
2. At the bottom of its page, choose **Disconnect** and the app's name, for example **Disconnect Gmail**.
3. Choose **Disconnect** to confirm.

Dvina stops reading from that app. What it already brought in stays, and you can connect it again any time. To have Dvina forget the app and its Pulse updates too, choose **Remove** and the app's name instead.

If you connected more than one account, you can disconnect just one: go to Settings › **Apps**, choose the app, then choose **Disconnect** from that account's menu. Your other accounts stay connected.

To disconnect every app at once, go to Settings › **Apps** and choose **Disconnect All Apps…**.

## Add your own MCP server

You can connect your company's own tools, like a wiki or an inventory system, by adding their MCP server.

1. Go to Settings › **Apps**, and under **Custom Apps**, choose **Add Custom App**.
2. Enter a **Name** and the **Server URL**.
3. If the server needs it, fill in **OAuth (Optional)**. Leave it blank when the server supports dynamic client registration.
4. Choose **Test Connection** to check that it works and see the tools it found.

> [!WARNING]
> Only connect servers you trust.

A custom app works like every other app, and its actions ask for approval the same way. See [Custom apps and MCP servers](/docs/connectors/custom-apps).

## On Enterprise

On Enterprise, admins choose which apps and custom servers members may connect, see every member's connections and can revoke any of them.
