Computer Control MCP

MCP server that provides computer control capabilities, like mouse, keyboard, OCR, etc. using PyAutoGUI, RapidOCR, ONNXRuntime. Similar to 'computer-use' by Anthropic. With Zero External Dependencies.

---

Quick Usage (MCP Setup Using uvx)

Note: Running uvx computer-control-mcp@latest for the first time will download python dependencies (around 70MB) which may take some time. Recommended to run this in a terminal before using it as MCP. Subsequent runs will be instant.

{
  "mcpServers": {
    "computer-control-mcp": {
      "command": "uvx",
      "args": ["computer-control-mcp@latest"]
    }
  }
}

OR install globally with pip:

pip install computer-control-mcp

Then run the server with:

computer-control-mcp # instead of uvx computer-control-mcp, so you can use the latest version, also you can `uv cache clean` to clear the cache and `uvx` again to use latest version.
