mcp-cst-studio
MCP server that exposes CST Studio Suite antenna design, RF simulation, and PCB layout workflows to AI agents.
What it does and how it connects
mcp-cst-studio is a Model Context Protocol server that gives AI agents access to CST Studio Suite for antenna design, RF and microwave simulation, and PCB layout. It exposes 173 tools across 20 categories, including geometry, materials, ports, boundaries, mesh, solvers, simulation, results, parameters, antenna templates, arrays, matching networks, diagnostics, optimization, PCB, and VBA.
It runs in two modes. Connected mode executes directly against a live CST install on Windows. Offline mode works on any OS without CST installed and generates VBA scripts that can be run in CST Studio Suite. Thirteen parametric antenna templates calculate dimensions from a target frequency, covering patch, dipole, monopole, horn, Yagi, helix, Vivaldi, slot, IFA, PIFA, spiral, and bowtie designs.
The PCB tools cover stackup creation, trace routing with impedance calculation, via modeling, and ground planes, and the material database holds more than 30 metals, dielectrics, and RF substrates. The README is explicit about the security model: VBA validation is a denylist, not a sandbox, so generated or user-supplied VBA should be treated as untrusted and CST run with least privilege.
