VentForge
Parametric vent-pattern designer: native desktop editor (PySide6) + MCP server, sharing one geometry core (shapely) and OpenCascade exports.
Install
uv tool install "ventforge[all]" # or: pipx install "ventforge[all]"
Extras: core (no extra) = MCP server + SVG/DXF/PNG export; gui = desktop editor; cad = STEP/STL export,
tube wrap and cut into a STEP part (OpenCascade); all = both.
Run
ventforge [design.vent.json] # desktop editor
ventforge --mcp # MCP server (stdio); `ventforge-mcp` does the same
Register with Claude Code (without installing first, uv fetches it on demand):
claude mcp add ventforge -- uvx --from "ventforge[all]" ventforge --mcp
For Claude Desktop, add the same command to claude_desktop_config.json under mcpServers.
The MCP server edits a .vent.json file (default ~/Documents/VentForge/current.vent.json); an editor window
with that file open reloads live, so you can watch the AI design. open_in_gui opens it.
Features
- 10 layout modes: grid (square/diamond/hexagon), random, path, spiral, concentric, fibonacci, crosslines, voronoi stone cracks, flow lines, custom points (AI-written arrangements).
- Dot shapes: circle, rounded rectangle, hexagon, polygon, star, custom outline.
- Gradients for size / spacing / angle / shape-morph, driven by point, line and curve controls, noise, or a grayscale image.
- Boundary: none, circle, rounded rectangle, custom drawn outline; margin, clip.
- Exports: PNG, SVG, DXF, STEP, STL; wrap onto a cylinder; cut into an existing STEP part.
- Stats: dot count, open-area ratio, min-wall violations. Undo/redo, presets, user library.
Layout
ventforge/model.py design schema (all parameters) · pattern.py geometry · export.py file output ·
gui.py editor · mcp_server.py MCP tools · presets/ (shipped in the package) · tests/ (pytest, 109 tests, including the MCP server over real stdio;
GUI test needs QT_QPA_PLATFORM=offscreen). Development: pip install -e ".[dev]".
CI (.github/workflows/ci.yml) tests Windows/macOS/Linux and publishes to PyPI on a v* tag.
