Remove image backgrounds from AI assistants with a LassoCut account (files, folders, URLs).
Remove image backgrounds from your AI assistant with a LassoCut account. The API is compatible with the remove.bg API.
Ask Claude (or any MCP-compatible assistant) to cut out product photos, portraits, whole folders, or images from a URL. Results are saved next to the originals as <name>-no-bg.<ext> and existing files are never overwritten — a name already taken gets -2, -3, and so on instead.
By default, every image is processed as a low-cost preview (0.25 credit, 50 free a month, up to 10 a day). Full-size output costs 1 credit per image and is only used when you explicitly ask for it; above 10 full-size images, the assistant must show you the cost and get your OK first.
Claude Desktop: download lassocut.mcpb and double-click it.
Claude Code:
claude mcp add lassocut -- npx -y lassocut-mcp
On Windows: claude mcp add lassocut -- cmd /c npx -y lassocut-mcp
Cursor / Windsurf (or any other MCP client that reads a JSON config):
{ "mcpServers": { "lassocut": { "command": "npx", "args": ["-y", "lassocut-mcp"] } } }
Requires Node.js 20 or later.
You need a LassoCut account and API key. Three ways to connect:
sign_in tool, which opens the LassoCut approval page in your browser and returns the approval link and a short code right away. Approve the connection in the browser, then ask the assistant to check your credits (get_credits) — the key is saved automatically in the background (the approval window stays open for a few minutes).lassocut command-line tool? This connector reads the same saved key from lassocut login, so no extra step is needed.LASSOCUT_API_KEY environment variable (or the api_key field in Claude Desktop's extension settings) to a key from your LassoCut account page. This always takes precedence over a signed-in key.remove_backgroundRemove the background of one or more images.
| Parameter | Description |
|---|---|
images | A file path, a folder path (its images, not subfolders), an http(s) URL, or a list of any of these. Up to 50 per call. |
size | preview (default) or full. |
background | transparent (default), a hex color such as #ffffff, or a color name. |
format | png (default), jpg, or webp. |
crop | Crop the result to the subject. |
output_dir | Where to save results. Must be an absolute path (~ is expanded). If omitted: next to each original file, or your Downloads folder (falling back to your home folder) for images fetched from a URL. |
confirm_cost | Set to true only after the user has confirmed the cost of a full-size request over 10 images. |
Files larger than 22 MB are skipped. Up to 3 small thumbnails are returned inline with the result.
get_creditsShows your current credit balance and the free previews available now (50 a month, up to 10 a day).
sign_inConnects a LassoCut account: opens the approval page in your browser and returns immediately with the link and code so you can approve at your own pace. Pass force: true to switch to a different account.
Images are sent only to the LassoCut API to remove their background; they are not sent anywhere else. See the LassoCut privacy policy for details.
