MCP Server for CST Studio Suite
A Model Context Protocol (MCP) server providing AI-driven access to CST Studio Suite for antenna design, RF/microwave simulation, and PCB layout.
Features
- 170 tools across 20 categories: geometry, materials, ports, boundaries, mesh, solvers, simulation, results, parameters, antenna templates, arrays, matching networks, diagnostics, optimization, PCB, and more
- Dual-mode operation: Connected mode (direct CST execution on Windows) and Offline mode (VBA script generation on any OS)
- 13 parametric antenna templates: Patch, dipole, monopole, horn, Yagi, helix, Vivaldi, slot, IFA, PIFA, spiral, bowtie — with automatic dimension calculations from target frequency
- PCB/SI tools: Stackup creation, trace routing with impedance calculation, via modeling, ground planes
- Material database: 30+ metals, dielectrics, and RF substrates with accurate electromagnetic properties
- VBA injection prevention: All generated VBA passes through security validation
- CST VBA reference: Built-in help system for CST VBA objects and methods
Installation
pip install mcp-cst-studio
Or from source:
git clone https://github.com/RFingAdam/mcp-cst-studio.git
cd mcp-cst-studio
pip install -e ".[dev]"
Configuration

Environment Variables
| Variable | Description | Default |
|---|---|---|
CST_PATH |
CST installation directory | Auto-detected on Windows |
CST_WORK_DIR |
Project working directory | ~/cst_projects |
CST_VERSION |
CST version year | 2026 |
Usage
Offline Mode (Any OS)
Works without CST installed. Tools generate VBA scripts that can be executed in CST Studio Suite.
"Design a 2.4 GHz rectangular patch antenna on FR-4 substrate"
→ Returns calculated dimensions + complete VBA script for CST
Connected Mode (Windows with CST)
When the CST Python library is available, tools execute directly:
"Create the antenna, run the time-domain simulation, and show me the S-parameters"
→ Builds geometry, configures solver, runs simulation, extracts results
Tool Categories
| Category | Tools | Description |
|---|---|---|
| Project | 8 | Create, open, save, close, export projects |
| Geometry | 13 | Brick, cylinder, sphere, cone, torus, extrude, loft, wire, polygon |
| Boolean | 4 | Add, subtract, intersect, insert operations |
| Transforms | 4 | Translate, rotate, mirror, scale |
| Materials | 15 | Create, load, assign materials; built-in material database; lossy metals; anisotropic |
| Ports | 8 | Waveguide, discrete, lumped, plane wave, Floquet ports |
