Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@LassoCut MCP remove the background from ~/Desktop/headshot.jpg"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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 per month). 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-mcpOn 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:
Ask the assistant to sign in. It calls the 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).
Already signed in with the lassocut command-line tool? This connector reads the same saved key from lassocut login, so no extra step is needed.
Set the 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.

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 left this month.
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.
Previews are the default everywhere; full-size output is never used unless asked for.
Requesting full size for more than 10 images at once requires an explicit confirmation, with the cost shown up front.
If your balance is too low for a full-size request, it is refused before any image is sent.
Files are only ever sent to the LassoCut API — see Privacy below.
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.
