### Description (declared)

# mcp-winaccess-win

**Version 1.8.0** · Windows-only desktop automation MCP server. Built directly on the OS APIs —
**ctypes** (`SendInput`, `ImageGrab`, Win32 windows, clipboard) and **UI Automation** via
`comtypes` — with **no `pyautogui` / `pywinauto` / `pywin32`**.

## Requirements

- **Windows 10/11 (x64)** — this package only runs on Windows.
- Python 3.10+.
- The server must run **inside an interactive desktop session** (a logged-in user), not as a
  background service — otherwise `SendInput`/UI Automation cannot reach the desktop.
- No administrator rights are required for normal user applications (see Limitations).
- OCR auto-install needs network access and 7-Zip (or an existing Tesseract install; see Troubleshooting).

## Install

```
pip install mcp-winaccess-win              # OCR support (pytesseract) is included
pip install "mcp-winaccess-win[vision]"    # optional: OpenCV template matching
```

The **Tesseract binary** (a system program, not a Python package) is downloaded and installed
automatically on first OCR use into `%LOCALAPPDATA%\mcp-winaccess\tesseract` (with `eng` + `rus`
language data). Use `--tesseract_cmd <path>` to point at an existing install, or
`--no-auto-tesseract` to disable the automatic install (see Troubleshooting).

## Run

```
python -m mcp_winaccess_win.server
# or the console script
mcp-winaccess-win
```

### Command-line arguments

| Argument | Default | Meaning |
|---|---|---|
| `--transport` | `local` | `local` (stdio) or `remote` (streamable-http) |
| `--listen` | `0.0.0.0` | HTTP bind address (remote only) |
| `--port` | `8765` | HTTP port (remote only) |
| `--token` | *(none)* | Bearer token required for HTTP (remote only) |
| `--tesseract_cmd` | `auto` | `auto`, or an explicit path to `tesseract.exe` |
| `--auto-tesseract` | on | automatic Tesseract install; `--no-auto-tesseract` disables it |
| `--no-shell` | off | disables the `run_command` tool (shell execution); enabled by default |

Local (stdio) is the default…
