CST Studio Suite MCP servers and AI agent skills

How AI connects to CST Studio Suite

An MCP server or skill can only do what CST Studio Suite lets programs do. CST Studio Suite exposes 2 automation interfaces:

• CST Python libraries (cst.interface, cst.results) (Python): CST installs Python packages under AMD64\python_cst_libraries. cst.interface controls a running Design Environment and its projects, and cst.results reads 0D and 1D results from a saved .cst file without the GUI. Scripts can run from CST's own Python menu or from an outside interpreter linked to the install. The official reference is in CST Help under Automation & Scripting > Python and the Dassault knowledge base, which need a customer login, so the link here is a reseller tutorial. Documentation
• VBA macros and the History List (COM) (COM automation): Every modelling step in CST is stored as a VBA block in the project's History List, such as a With Brick ... .Create End With block. Writing new blocks with AddToHistory keeps the model parametric, so changing a parameter and rebuilding moves the geometry. On Windows the CSTStudio.Application COM object exposes the same macro language to outside programs, which is how the PowerShell- and pywin32-based servers work across CST versions.

What Dassault Systemes offers

Dassault Systemes has not announced an MCP server or AI assistant for CST Studio Suite as of this check. The CST product page lists solvers, the design environment, optimisation, system modelling and 3DEXPERIENCE integration, with no AI or agent features. Automation remains the customer's job, through CST's Python libraries and VBA macros.

What you can do with CST Studio Suite and AI

• Build an antenna from a template or from scratch, such as a patch, dipole, horn or Vivaldi, with substrate materials, ports and far-field monitors.
• Choose the time-domain, frequency-domain or eigenmode solver, run it, and read S-parameters, VSWR and input impedance from the result tree or a Touchstone export.
• Extract far-field gain, beamwidth, front-to-back ratio, axial ratio and efficiency from a solved project.
• Sweep or optimise parameters with CST's built-in optimizers or a server-side loop, keeping one project per case.
• Assemble a Design Studio schematic with Touchstone blocks and lumped parts for field-circuit co-simulation.
• Run a raw VBA macro or a history step when no dedicated tool exists, such as Floquet ports or plane-wave excitation.

Installing

The listings here document setup for Claude Code, Claude Desktop, Codex, Cursor and OpenCode. Install steps, copied from each project's own documentation, are on each listing's page. Most CST Studio Suite integrations run on your own computer next to CST Studio Suite, so you need CST Studio Suite installed and licensed on the same machine unless the listing says otherwise.
