ansys-lumerical-mcp 0.1.0

Model Context Protocol (MCP) server for Ansys Lumerical through PyLumerical

PyLumerical MCP Server

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
