Techtenstein Background Removal MCP

MCP server that gives your Claude, Cline, or Cursor session the ability to strip backgrounds from any image — product photos, portraits, cars, or general subjects — returning a transparent PNG. Powered by the Techtenstein Background Removal API.

Tools exposed

• remove_background_url(image_url, mode="auto") — Strip background from an image URL
• remove_background_base64(image_base64, mode="auto") — Strip background from a base64 image (user upload)

Modes: auto, product, portrait, car.

Install (Claude Desktop)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "techtenstein-bg": {
      "command": "uvx",
      "args": ["techtenstein-bg-mcp"],
      "env": {
        "TECHTENSTEIN_API_KEY": "your_key_from_techtenstein.com"
      }
    }
  }
}

Restart Claude Desktop. remove_background_url and remove_background_base64 will appear as available tools.

Install (Cline / VS Code)

Same config path as Claude Desktop — Cline auto-detects.

{
  "mcpServers": {
    "techtenstein-bg": {
      "command": "uvx",
      "args": ["techtenstein-bg-mcp"],

Example usage

Once installed, ask Claude:

"Remove the background from this product photo: https://cdn.example.com/shoe.jpg"

Claude will call remove_background_url in product mode and return a transparent PNG.

Or for a portrait:

"This is a headshot — cut out just the person: https://example.com/team-photo.jpg"

Claude will call remove_background_url(image_url, mode="portrait").
