This is an MCP server that analyzes the screen with OmniParser and automatically operates the GUI.
Confirmed on Windows.

This is MIT license, but Excluding submodules and sub packages.
OmniParser's repository is CC-BY-4.0.
Each OmniParser model has a different license (reference).

1. Please do the following:

git clone --recursive https://github.com/NON906/omniparser-autogui-mcp.git
cd omniparser-autogui-mcp
uv sync
set OCR_LANG=en
uv run download_models.py

(Other than Windows, use export instead of set.)
(If you want langchain_example.py to work, uv sync --extra langchain instead.)

2. Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "omniparser_autogui_mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "D:\\CLONED_PATH\\omniparser-autogui-mcp",
        "run",
        "omniparser-autogui-mcp"
      ],
      "env": {
        "PYTHONIOENCODING": "utf-8",
        "OCR_LANG": "en"
      }
    }
  }
}

(Replace D:\\CLONED_PATH\\omniparser-autogui-mcp with the directory you cloned.)

env allows for the following additional configurations:

• OMNI_PARSER_BACKEND_LOAD
  If it does not work with other clients (such as LibreChat), specify 1.

• TARGET_WINDOW_NAME
  If you want to specify the window to operate, please specify the window name.
  If not specified, operates on the entire screen.

• OMNI_PARSER_SERVER
  If you want OmniParser processing to be done on another device, specify the server's address and port, such as 127.0.0.1:8000.
  The server can be started with uv run omniparserserver.

• SSE_HOST, SSE_PORT
  If specified, communication will be done via SSE instead of stdio.

• SOM_MODEL_PATH, CAPTION_MODEL_NAME, CAPTION_MODEL_PATH, OMNI_PARSER_DEVICE, BOX_TRESHOLD
  These are for OmniParser configuration.
  Usually, they are not necessary.

• Search for "MCP server" in the on-screen browser.
