# Uploads & assets

> Bringing your own images into Melius.

You can bring your own images into a canvas as **file nodes**. Uploaded images become first-class assets — they can be referenced by edges, passed to image-tool models, or used as references on video nodes.

## What's supported

* **Images** — JPEG, PNG, WebP, HEIC.
* **Maximum size** — limit depends on plan; current limits are shown in the upload dialog.

## What's not supported

* **Video uploads are not supported.** Video must be generated on the canvas. (If this changes, the upload dialog will say so.)
* Audio uploads are not supported.

## How to upload

* **In the UI** — drag an image onto the canvas, or pick **Upload** from the node toolbar.
* **MCP** — call [`file_upload`](/mcp/tools#files), `curl` the file to the returned URL, then call [`file_upload_complete`](/mcp/tools#files).
* **CLI** — `mel upload <path>`.

## Sandboxed-agent network allowlist

If you're running an MCP-driven agent in a sandboxed environment (Claude Code's sandboxed shell, for example), the sandbox needs network egress to `*.melius.com` for uploads to succeed.

Add this exact entry to the sandbox's network allowlist:

```
*.melius.com
```

For Claude Desktop / Claude Code, the toggle lives in **Organization Settings → Capabilities → Code execution**. See the [MCP overview](/mcp/overview#uploading-images) for the full setup.
