# External connections

> Give bunny extra abilities by connecting outside apps like Gmail and Google Calendar, or by adding remote MCP tool servers.

bunny already comes with a set of [built-in tools](/user/chat/built-in-tools). You can give it even more to work with in two ways: connect an outside app, or add a remote tool server. Both live in **Settings** and both need you to be signed in.

<Note>
  Whenever bunny wants to use a connector or a tool server, it asks for your approval first. See [Tool approvals](/user/chat/permissions).
</Note>

## Connect an app

Connectors link bunny to apps you already use, like Gmail and Google Calendar, so it can act on them for you. Once a connector is on, you can ask bunny to read your recent emails or list your upcoming events, and it does the work in that app.

<Steps>
  <Step title="Open Connectors">
    Go to **Settings** › **Connectors**.
  </Step>

  <Step title="Switch a service on">
    Flip a service on. A popup opens its own sign-in and consent screen so you can approve access.
  </Step>

  <Step title="Confirm it connected">
    When it finishes, the service shows **Connected**.
  </Step>
</Steps>

Inside a connected app you can enable or disable its individual tools, so bunny only gets the abilities you want. To cut off access entirely, disconnect the service.

## Add a tool server (MCP)

An MCP server is an add-on tool server that bunny connects to over the internet. Connecting one hands bunny a fresh set of tools it did not have before. This is a more advanced option, so reach for it when someone gives you a server address to add.

<Steps>
  <Step title="Open MCP">
    Go to **Settings** › **MCP**.
  </Step>

  <Step title="Add the server">
    Choose **Add MCP server**, then give it a name and its address (a URL).
  </Step>

  <Step title="Sign in if needed">
    If the server requires a login, tick **Sign in with OAuth** and complete the sign-in.
  </Step>
</Steps>

<Warning>
  Only add tool servers you trust. A connected server can offer bunny new tools, and bunny will ask your approval before using any of them.
</Warning>
