At a glance

Type: MCP server
Works with: Ansys HFSS / Maxwell
How it connects: Drives a running copy of the tool
Access: Can modify models
Tool versions: AEDT 2026.1 with PyAEDT 0.25.1 and Python 3.12 (author's test setup)
Operating systems: Not stated in its documentation
Needs a Ansys HFSS / Maxwell licence: Yes
Transport: Local (stdio)
AI clients documented: VS Code
Licence: MIT
Language: Python

What it can do

Connects to or launches HFSS over gRPC and keeps the session alive between tool calls, saving session state to a JSON file.
Creates projects, boxes, cylinders and spheres, wave ports, radiation boundaries, design variables and solution setups, runs the analysis and extracts S-parameters.
Builds a searchable knowledge base from the Ansys product documentation PDFs on your machine and answers modelling questions about ports, boundaries, setups and meshing from it.

Limitations

Geometry tools cover only basic primitives; anything else needs extending the server.
The README (in Chinese) documents known PyAEDT version differences for radiation boundaries, wave port faces, S-parameter extraction and far-field setup over gRPC.
No licence file in the repository; the README states MIT.
