Visio MCP Server lets an assistant build and modify Microsoft Visio diagrams programmatically. It works by controlling a real Visio installation through Microsoft's COM automation interface using pywin32, so the result is a genuine Visio document with native shapes rather than an exported approximation. Tools cover creating new diagrams and opening existing ones, adding shapes such as rectangles, circles and lines, connecting shapes with the various connector types Visio provides, adding text to shapes, listing every shape in a document so the model can see what is already there before changing it, and saving files. That read-then-modify capability is what allows iterative work on an existing diagram rather than only generation from scratch. The requirements are strict and follow from the COM approach: a Windows operating system, Microsoft Visio Professional or Standard actually installed, and Python 3.12 or newer — it cannot run on macOS or Linux, and it cannot run without a Visio licence. The GitHub repository is archived and no longer maintained. The audience is Windows users who produce process diagrams, network diagrams or floor plans in Visio and want an assistant drafting them, treating this as a starting point to fork.
