Optional add-ons: integrations, Microsoft 365 sign-in, and Discover

Optional add-ons are integrations that expand what Otto can use on your behalf - extra tools beyond the core connectors. This section also holds the Microsoft 365 sign-in card and a Discover button that finds tools you have already configured for other apps and adopts them in a click.

Where this lives

Open the Connectors tab (right pane More menu, then Connectors) and scroll to the Optional add-ons section.

Reading an integration card

Each integration is a card that expands in place when you click it. On the card you will see:

• An On badge when the integration is active.
• An access label showing how far the tool is allowed to reach.
• A Found here badge when the integration was discovered already configured on your computer.

And inside the expanded card, its controls:

• Turn on / Turn off - enable or disable the integration without removing it.
• Needs its key - appears when the integration requires a key before it can run; click it to provide one.
• Set this up for me - the engine installs and configures the integration and walks you through only the parts that need you.
• Manage / About - open the tool's own page or read what it does.
• Remove - available on custom integrations you added yourself.

Sign in to Microsoft 365

The Microsoft 365 card uses a device code, which means your Microsoft password never touches the app:

1. Find the Microsoft 365 card in Optional add-ons.
2. Click Sign in to Microsoft. A device code appears in large text, and the app opens microsoft.com/devicelogin for you.
3. Enter the code on that Microsoft page and sign in there as usual.
4. The app detects on its own when you have finished - no need to come back and confirm anything.

You can Sign out from the same card whenever you like, and the card has its own Turn on / Turn off control like any other integration.

Discover integrations you already have

If you use Claude Code, Claude Desktop, or Cursor, you may already have useful tools configured for them. Click Discover integrations and the app scans those configs for you. Each find appears with an Add button - click it to adopt the tool into Booked Solid.

One rule to remember: discovered tools start read-only. They can look but not touch until you decide otherwise. To give a tool more reach, go to Settings > Permissions and widen its access there. Starting narrow keeps a newly adopted tool from doing anything you did not expect.
