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

Run without cloning

uvx --from git+https://github.com/ansys/pyaedt-mcp.git ansys-aedt-mcp

Install locally

pip install git+https://github.com/ansys/pyaedt-mcp.git

Or use uv:

uv pip install git+https://github.com/ansys/pyaedt-mcp.git

Install for development

git clone https://github.com/ansys/pyaedt-mcp.git
cd pyaedt-mcp
pip install -e .
pre-commit install

Or use uv:

git clone https://github.com/ansys/pyaedt-mcp.git
cd pyaedt-mcp
uv pip install -e .
pre-commit install

Requirements

• Python 3.11 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:

``bash "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.

1. Start PyAEDT-MCP:

``bash ansys-aedt-mcp ``

You can also use one of these common variants:

```bash # 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 ```

1. Point an MCP client at the server:

*Visual Studio Code

``json { "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

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

How the repository is organized

The core package is in src\ansys\aedt\mcp:

| File | Role | | --- | --- | | __main__.py | Module entry point that forwards to the CLI launcher | | server.py | CLI parsing, app setup, context creation, startup cleanup, and transport selection | | tools.py | Runtime tool implementations for AEDT lifecycle, project, scripting, and export workflows | | helpers.py | Small utilities for probing endpoints, normalizing versions, and extracting model data | | prompts.py | System prompt content shown to MCP clients | | contexts.py | Optional context helper tools enabled by --include-context | | toolsets.py | toolsets://definition resource used for logical tool discovery | | aedt_helper\startup_code.py | Startup code loaded into the persistent Python session |

Other top-level folders include:

• doc\source: Sphinx documentation
• tests: Unit and integration coverage
• docker: Container assets
• examples: Sample assets used by the project

Development workflow

To contribute, see Contribute in the PyAEDT-MCP documentation.

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.

For more information, see Add a new tool in the PyAEDT-MCP documentation.
