# VisualTorch (MCP server)

> VisualTorch is an MCP server that adds tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Render PyTorch architecture diagrams and animated GIF reveals from trusted model source. It has 336 GitHub stars, is released under the MIT license and runs locally with uvx visualtorch.

VisualTorch aims to help visualize Torch-based neural network architectures. It currently supports generating flow-style, graph-style, and LeNet-style architectures for PyTorch Sequential and Custom models. Its original visual styles were inspired by visualkeras, pytorchviz, pytorch-summary, and torchview; since then, it has grown its own unified tracing backend and architecture-handling logic well beyond its origins.
