qtpy-mcp

# qtpy-mcp MCP server that lets an AI agent **find, screenshot, GIF-record and drive Qt widgets** in running applications and DCCs (Houdini, Blender, Maya, Nuke, ...), built on [Qt.py](https://github.com/mottosso/Qt.py) so it works with PySide6, PyQt6, PySide2 and PyQt5. It is a fork of [0xCarbon/qt-mcp](https://github.com/0xCarbon/qt-mcp) (MIT OR Apache-2.0): same tool set, plus Qt.py, many-apps-at-once routing, semantic widget search and GIFs. ``` "screenshot the PIPE-1234 window's docked Render Queue" ┌────────────────────┐ "now the widget labelled 'Name goes here:' in DEV-1515" ──► │ Houdini pid 4121 │ probe "record a GIF of Houdini process 1252151's 'Foo bar'" ├────────────────────┤ │ │ Houdini pid 1252 │ probe MCP client ──stdio──► qtpy-mcp ── registry + JSON-RPC ───► ├────────────────────┤ (routes) (127.0.0.1, token) │ Blender pid 7770 │ probe └────────────────────┘ ``` ## What you can ask for - **Find by meaning**, not by ref: text, window title, class, `objectName`, placeholder, **tooltip, whatsThis, statusTip**, accessible name, tab text, dynamic properties, even **style sheet**. Fuzzy-ranked; each hit says which field matched. - **Screenshot** a whole window, a dialog, or any sub-widget such as a docked panel. A match on a label like `Name goes here:` captures the form around it (`expand="auto"`; also `self`, `parent`, `buddy`, `window`). - **Record a GIF** (`qt_record_gif`, or `qt_record_start` / `qt_record_stop` while you interact). The probe grabs frames with `QWidget.grab()` and Pillow encodes them, so it behaves the same on Windows, Linux and macOS: no ffmpeg or screen-capture APIs. - **Many applications at once.** Several Houdinis, Blender and Maya can be open together; one agent connection addresses any of them (see below). - Everything upstream pr…
