Microsoft OneDrive Toolkit

The Microsoft OneDrive toolkit connects a OneDrive account to EKB Platform using OAuth and lets agents and workflows list drives and folder contents, search and read files, upload and manage files and folders, and create sharing links. The toolkit uses Microsoft Graph and runs with the connected user’s OneDrive permissions.

Prerequisites

A Microsoft work or school account with access to the OneDrive files you intend to use.
An EKB Platform project where you can configure an agent or workflow.
Your EKB Platform administrator must have configured a Microsoft OAuth integration with the required Graph permissions (Files.ReadWrite.All and Sites.ReadWrite.All for site drives) before you can connect.
For shared-with-me items, Files.ReadWrite.All must be consented by your administrator.

Enable only the operations required for the task. Leave write, delete, move, and sharing tools disabled until explicitly needed. Test write operations on a disposable folder first. Never pass a display name as an item ID — always use the item_id and drive_id values returned by list or search tools.

Setup

Open an agent or workflow in EKB Platform

Create or open an EKB Platform agent and add the Microsoft OneDrive toolkit, or add a Microsoft OneDrive node to a workflow.

Enable only the tools you need

Start with read-only tools: List Drives, List Folder Contents, Search Files, Get File Metadata, and Read File Content. Leave write and sharing tools disabled until needed.

Send a request or select the Microsoft sign-in action when EKB Platform prompts for it. Sign in with the Microsoft work or school account that owns the files and grant the requested permissions.

Test with read actions first

Run List Drives and List Folder Contents to confirm access. Use a disposable test folder for any write operations and verify the results in OneDrive on the web after each write test.

Available tools

Navigate

Tool	Description
List Drives	Lists the personal drive and accessible group or site drives. Run this first to get drive IDs.
List Folder Contents	Lists files and folders in a folder. Prefer item ID over path.
Get Folder Tree	Returns a depth- and breadth-capped folder tree (max depth 5).
Get File Metadata	Returns ID, name, size, modified time, web URL, and folder or file flags for an item.
Get Special Folder	Resolves a well-known folder such as Documents or Photos.

Discover

Tool	Description
Search Files	Searches OneDrive by file name or keyword. Optional drive ID and result limit.
List Recent Files	Returns recently accessed items, ordered by activity.
List Shared With Me	Lists files shared with the signed-in user. Requires `Files.ReadWrite.All`.
Resolve Sharing URL	Converts a OneDrive, SharePoint, or 1drv.ms sharing link into drive and item IDs.

Read

Tool	Description
Read File Content	Extracts text from a file. Text files capped at 10 MB; binary at 50 MB; extracted text truncated at 100,000 characters.
Export Item	Exports an Office document to PDF and extracts its text.
Get Preview Link	Returns a short-lived preview URL for a file.
Get Item Versions	Lists previous versions of a file.
List Permissions	Lists sharing permissions on a file or folder.

Write

Tool	Description
Upload File	Uploads a new file. Files larger than 4 MB use a chunked upload session. Conflict behavior defaults to rename.
Create Folder	Creates a folder under a parent item or path.
Update File	Overwrites an existing file. Re-read metadata first if the file may have changed.
Rename Item	Renames a file or folder by item ID.
Move Item	Moves a file or folder to a new location by item ID.
Copy Item	Copies a file or folder. Copy is asynchronous and may still be in progress when the tool returns.
Delete Item	Moves the item to the recycle bin. Recycle-bin deletes do not free drive quota.

Tool	Description
Create Sharing Link	Creates a view or edit sharing link with organization or anonymous scope, as allowed by tenant policy.
Invite Users To Item	Invites people by email with read or write roles.

Use cases

Search OneDrive for a quarterly report, read its content, and summarize it in a workflow.
Upload a generated file to a team drive folder and create a sharing link for stakeholders.
List folder contents and find recently modified files before triggering a downstream notification.
Export a Word document to PDF and pass the extracted text to an agent for analysis.
Resolve a sharing URL from a Slack message into a file ID and read its content directly.

Troubleshooting

Symptom	Likely cause	Fix
Redirect URI mismatch	The OAuth redirect URI in Microsoft Entra does not exactly match the one in EKB Platform Super Admin.	Ask your administrator to ensure both URIs match exactly, including protocol and path.
`AADSTS53003` Conditional Access error	The Microsoft Entra tenant blocks app-only token issuance.	This is expected for user OneDrive data — users must sign in with the delegated OAuth flow. The Super Admin connection test can still succeed.
`403` insufficient permissions	The required Graph permissions have not been consented by an administrator.	Ask your administrator to grant `Files.ReadWrite.All` and `Sites.ReadWrite.All` for site drives.
`404` item not found	The item ID is incorrect, the wrong drive ID is specified, or OneDrive is not provisioned for the account.	Use List Drives and List Folder Contents to find the correct `item_id` and `drive_id`.
`412` lost update on file write	The file changed between when it was read and when the write was attempted.	Re-read the file metadata and retry the write operation.
`507` insufficient storage	The drive is full. Recycle-bin deletes do not free quota.	Empty the recycle bin in OneDrive on the web to free space.
File is locked or checked out	Another user has the file open for editing.	Wait for the owner to close or check in the file, then retry.
Workflow cannot use a file from a previous step	A display name was passed instead of an item ID.	Use the Variables picker to pass the prior node’s `id` and `drive_id` values — not the file’s display name.
