WHAT IT DOES

What transkribus_upload_create_s3 does on Transkribus

AI agents use transkribus_upload_create_s3 to create or update resources in Transkribus, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Transkribus environment.

RISK

Why transkribus_upload_create_s3 is rated Medium

This tool creates a new upload resource/entry by ingesting data from an S3 source. This is a write operation that modifies server state by adding a new upload record, but it does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could fill storage, create unwanted upload records, or process sensitive files without authorization, but the effect is reversible via deletion.

From the tool's definition Tool name contains 'upload_create' and description states 'Create an upload from an S3 source.' The verb 'create' and 'upload' indicate data creation/modification operations.
