viznoir

viznoir is an MCP server that gives AI agents full access to VTK's rendering pipeline, with no ParaView GUI, no Jupyter notebooks and no display server. The agent reads simulation data, applies filters, renders images and exports animations, all headless. It works with Claude Code, Cursor, Windsurf, Gemini CLI and any MCP client, and installs with pip on Python 3.10 or later with EGL headless rendering.

The server exposes 22 tools, 12 resources and 4 prompts across rendering, filters, analysis, probing, animation, comparison and export. Rendering covers standard, cinematic, batch and volume rendering; filters include slice, contour, clip, streamlines and isosurface; analysis covers data inspection, physics inspection, statistics and data analysis. It reads 50-plus file formats including OpenFOAM, VTK, CGNS, Exodus, STL and glTF.

The README also describes seven physics-aware animation presets that bind a rendering primitive to a physical phenomenon, such as streamline growth, clip sweep and warp oscillation, and a story composition tool that assembles inspected, rendered and annotated panels with LaTeX-rendered governing equations into a publication-ready narrative.
