What it does and how it connects

cst-mcp is an MCP stdio server for local CST Studio Suite automation on 64-bit Windows. An MCP client can manage projects, build geometry, configure simulations and read results through the installed CST Python API and model-history VBA. It derives from ismailakdag/cst-studio-mcp, which Gonçalo Gomes maintains as this version.

The server starts in manual connection mode and connects to a CST session only when the client calls cst_connect. Tool categories cover connection, project, workflows, simulation, results, parameters and diagnostics, with dedicated modeling tools for geometry, materials and booleans available through the CST_TOOLSETS setting. Raw VBA execution is opt-in, and the README calls its argument checks a best-effort filter, not a sandbox.

Live automation needs an installed and licensed CST Studio Suite (the examples use CST 2025, with discovery defaulting to 2026) and a Python interpreter matching the installed CST Python library ABI. Offline tests run without CST, and the README is explicit that installation discovery alone does not prove import compatibility.
