# MCP Server for CST Studio Suite

A Model Context Protocol (MCP) server providing AI-driven access to [CST Studio Suite](https://www.3ds.com/products/simulia/cst-studio-suite) for antenna design, RF/microwave simulation, and PCB layout.

## Features

- **173 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

```bash
git clone https://github.com/RFingAdam/mcp-cst-studio.git
cd mcp-cst-studio
pip install -e ".[dev]"
