Uploading and managing assets
Each brand has isolated storage. An Asset uploaded to Brand A is not visible in Brand B.
Where to upload — open Assets in the right-hand context panel, or use the full Assets/Files page on a hosted Agent brand. Drag and drop or choose the upload button; multiple files are supported.
Connect storage — machine-free brands use project-scoped cloud Assets. The same items are available in the dashboard and through MCP asset tools; no hosted machine is required.
Agent storage — hosted brands expose their project filesystem. Uploaded resources persist across chats and are available to workflows and skills. Markdown and other supported text files can be edited from the file viewer.
Sharing Agent outputs with an MCP assistant — Agent work created under the hosted resources/ folder lives on that brand's machine volume. An authorized MCP assistant can list eligible file metadata with list_workspace_files_for_export, snapshot selected paths with export_workspace_files_to_assets, then discover and read those snapshots with the normal Assets tools. Export is selective and does not automatically publish or mirror the whole workspace.
Supported formats — text (.txt, .md), PDFs, Word (.docx), spreadsheets (.csv, .xlsx), presentations (.pptx), images (.png, .jpg), and most plain-text source code files.
Size limit — uploads are limited to 50 MB per file. MCP text writes have a separate 1 MB limit; larger or binary MCP uploads use the prepare/upload/finalize flow.
Preview and download — select an item to preview supported text, documents, or media. Download the original when you need to work outside Magister.
Removing uploads — choose Delete on a user-uploaded item. Deletion is permanent. Generated brand, plan, and audit documents are canonical, read-only assets and cannot be deleted like an upload.
