Ansys HFSS / Maxwell AI: MCP servers and agent skills

How AI connects to Ansys HFSS / Maxwell

An MCP server or skill can only do what Ansys HFSS / Maxwell lets programs do. Ansys HFSS / Maxwell exposes 2 automation interfaces:

• PyAEDT (ansys-aedt-core) (Python): PyAEDT is Ansys's open-source Python library for Electronics Desktop. One Desktop object starts or attaches to AEDT, and app classes such as Hfss, Maxwell3d, Q3d, Icepak and Circuit expose the modeler, boundaries, excitations, setups and post-processing. From AEDT 2022 R2 it talks to AEDT over gRPC, which is what lets an MCP server attach to a session on another machine; older releases fall back to COM on Windows. Keep PyAEDT in step with your AEDT release, because method names change between versions. Documentation
• Native AEDT scripting API (oDesktop, oEditor, modules) (COM automation): Underneath PyAEDT sits the AEDT object model that the Record Script command writes in IronPython or VBScript: oDesktop, oProject, oDesign, oEditor and modules fetched with GetModule, such as BoundarySetup and AnalysisSetup. On Windows it is registered as the Ansoft.ElectronicsDesktop ProgID, so any COM client can drive it. One community server uses this route to reach HFSS 2019, and another exposes the raw modules next to its PyAEDT tools.

What Ansys (Synopsys) offers

Ansys publishes PyAEDT-MCP from its own GitHub organisation: version 0.3.x on PyPI, Apache-2.0, classed as Alpha. Separately, Ansys Engineering Copilot, an in-product assistant that answers questions, searches Ansys learning resources and opens support cases, was announced for Electronics Desktop and HFSS in the 2025 R2 release. The copilot is a help tool; only the MCP server lets an outside agent operate AEDT.

What you can do with Ansys HFSS / Maxwell and AI

• Build a parametric antenna, such as a coax-fed patch or half-wave dipole, at a target frequency with substrate, ports, radiation boundary and far-field sphere already defined.
• Add an adaptive setup and frequency sweep, solve, and read back S11, resonance, -10 dB bandwidth, VSWR and input impedance.
• Extract far-field gain, axial ratio and radiation patterns, and export Touchstone files for use in a circuit simulator.
• Run parametric sweeps, optimetrics or sensitivity and tolerance studies on design variables.
• Attach to a Maxwell, Q3D or Icepak design in the same AEDT session and run PyAEDT code against it, from coil windings and force to thermal residual checks.

Installing

The listings here document setup for Claude Code, Claude Desktop, Cline, Codex, Continue, Cursor, Hermes Agent, OpenCode, VS Code, VS Code (GitHub Copilot) and Windsurf. Install steps, copied from each project's own documentation, are on each listing's page. Most Ansys HFSS / Maxwell integrations run on your own computer next to Ansys HFSS / Maxwell, so you need Ansys HFSS / Maxwell installed and licensed on the same machine unless the listing says otherwise.
