Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

PyLumerical MCP Server

[](https://docs.pyansys.com/) [](https://www.python.org/) [](https://opensource.org/licenses/Apache-2.0)

PyLumerical MCP Server provides a Model Context Protocol (MCP) server that enables AI assistants to interact with Ansys Lumerical (FDTD, MODE, DEVICE, INTERCONNECT) through PyLumerical. This server enables natural language interaction with Lumerical for photonics and electromagnetic simulation workflows.

Overview

Key features:

  • Multi-session management: Open, list, and close multiple concurrent

Lumerical sessions (FDTD, MODE, DEVICE, INTERCONNECT) under user-chosen names.

  • Persistent Python execution: Run arbitrary Python and PyLumerical code

against live Lumerical handles, with state preserved across tool calls.

  • Workflow guidance: Access context and best practices for Lumerical simulations.
  • Cross platform support: Enable Windows and Linux support with headless CAD.

Prerequisites

  • Python 3.11, 3.12, 3.13, or 3.14
  • Ansys Lumerical installation
  • Ansys Lumerical license
