SharePoint

Let your app read and store documents in a SharePoint site, where your company already keeps its files.

Ask Claude to connect it

Included on every plan. An admin approves it once.

What your app can do with it

✓Access to one site only, nothing else in your company
✓Files stay where your organisation already manages them
✓Works next to Microsoft 365 email in the same app

For your IT admin

Setting it up

Done once, in your company's own account with Microsoft.

Create an app registration in the customer’s Entra tenant, a separate one from mail since the permissions differ.

Add the Sites.Selected application permission and grant admin consent.

Grant that registration access to the specific site, not the whole tenant.

Create a client secret, and note the site id from the site URL.

For developers

What your app receives

Reads and writes documents in a customer’s SharePoint site, the place most organisations already keep the files an application needs, rather than a bucket nobody governs. Uses a Graph app registration scoped with Sites.Selected and granted access to one site, so your application can reach that library and nothing else in the tenant. Its variables carry the SHAREPOINT_ prefix rather than GRAPH_, because this is a different registration from the mail one, and an application commonly holds both.
