ansys-aedt-mcp 0.1.3

PyAEDT-MCP is an MCP (Model Context Protocol) server for Ansys Electronics Desktop (AEDT). It gives you reliable AEDT tools and a persistent PyAEDT-backed Python session for tasks that do not fit a dedicated tool.

What PyAEDT-MCP does

PyAEDT-MCP supports this runtime loop:

1. Check whether AEDT is installed or already reachable.
2. Launch AEDT or connect to an existing gRPC session.
3. Open projects, create designs, run analyses, inspect the model, and export results.
4. Use run_python_code or run_python_script for custom PyAEDT work.

Supported AEDT applications include HFSS, Maxwell 2D/3D, Q2D, Q3D, Icepak, Circuit, TwinBuilder, Mechanical, EMIT, RMXprt, and HFSS 3D Layout.

Install

cd pyaedt-mcp
uv pip install -e .
pre-commit install

Requirements

• Python 3.12 or later
• AEDT 2022 R2 or later for gRPC workflows
• A local AEDT installation or a reachable remote AEDT gRPC endpoint

Quick start

1. Start AEDT in gRPC mode when connecting to an existing session:

   "C:\Program Files\ANSYS Inc\v261\AnsysEM\ansysedt.exe" -grpcsrv 50051
   

   Or, just launch AEDT normally. It automatically starts a gRPC server.

   PyAEDT-MCP can also launch AEDT for you if it is not already running.

2. Start PyAEDT-MCP:

   ansys-aedt-mcp
   

   You can also use one of these common variants:

   # Connect on startup
   ansys-aedt-mcp --connect --machine localhost --port 50051
   
   # Expose HTTP transport instead of STDIO
   ansys-aedt-mcp --transport http --http-host 127.0.0.1 --http-port 8080
   
   # Register optional context helper tools
   ansys-aedt-mcp --include-context
   
   # Hide AEDT-only tools until a connection exists
   ansys-aedt-mcp --dynamic-tool-discovery
   

3. Point an MCP client at the server:

   *Visual Studio Code

   {
     "mcp": {
       "servers": {
         "pyaedt-mcp": {
           "command": "uvx",
           "args": [
             "--index-strategy", "unsafe-best-match",
             "--from", "git+https://github.com/ansys/pyaedt-mcp.git",
             "ansys-aedt-mcp"
           ]
         }
       }
     }
   }
   

   Claude Desktop

   {
     "mcpServers": {
       "pyaedt-mcp": {
         "command": "uvx",
         "args": [
           "--from", "git+https://github.com/ansys/pyaedt-mcp.git",
           "ansys-aedt-mcp"
         ]
       }
     }
   }

Add a new tool

Most tools require a live AEDT connection. Tag those tools with REQUIRES_AEDT_TAG in src\ansys\aedt\mcp\tools.py so they can be hidden until the session exists when dynamic discovery is enabled.
