viznoir MCP server

viznoir is a helper that lets your AI make pictures and short videos from scientific simulation files. It is made for people who work with simulation results, like engineers and researchers, and who would rather ask in plain words than click around a heavy graphics program. If you have files from tools like OpenFOAM, VTK or CGNS and want to see what is inside them, this is for you.

What this MCP server does

You tell your AI something like open this file and show me the pressure field. Your AI passes that request to viznoir. viznoir opens the file, reads the numbers inside, and uses a well known drawing engine called VTK to build an image. It can also cut the data with a slice, draw lines that follow the flow, or make a short animation. When it is done, it saves the picture or video and tells your AI where the file is, so you can open it.

What you can do with it

• Render a field from a simulation file as a clear image
• Slice through your data to see what is inside
• Draw contour lines or surfaces at a chosen value
• Show streamlines that follow the flow
• Make a short animation from a series of time steps
• Compare two cases side by side
• Save the result as PNG, WebP, MP4 or GLTF

Try asking your AI

• “Open cavity.foam and render the pressure field with nice lighting”
• “Slice the temperature field in half and save it as a PNG”
• “Show me the streamlines in this combustion case”
• “Make a short animation of the vorticity over time”

What it gives back to you

You get back a saved image or video file, plus a short note in the chat telling you where it was saved. Sometimes your AI also gives you a quick summary of what was found, like the list of fields in the file or a few numbers from the data. The picture itself opens in any normal image viewer, and the video plays like any other clip.

Before you start

Who it's for

Engineers, researchers and students who work with simulation data and want pictures without learning a heavy graphics program.
