Tidy3D + AI 💡#

Ushering in a new era of AI-assisted photonic design

We are pleased to announce the release of the new Tidy3D Extension, which enables seamless building, visualization, and iteration on electromagnetic simulations within Visual Studio Code or Cursor. The extension automatically detects simulations in Tidy3D Python scripts and notebooks, opens an interactive 3D viewer alongside your code, and enables the IDE AI assistant to leverage the integrated FlexAgent MCP server for an intelligent, physics‑aware assistance experience.

Tidy3D Extension

Key Components#

FlexAgent MCP#

FlexAgent MCP is a physics-aware AI assistant that understands Tidy3D workflows and electromagnetic simulation concepts. Unlike generic coding assistants, FlexAgent provides specialized knowledge and can control the 3D Viewer to provide comprehensive, context-aware support.

Key Capabilities:

  • Natural Language Interaction – Build, modify, and analyze simulations using plain English

  • Physics-Aware – Understands electromagnetic simulation concepts and Tidy3D’s API

  • Learning & Troubleshooting – Get explanations and fix simulation issues

  • Code Generation – Create complete simulation setups from scratch

  • Result Analysis – Interpret and visualize simulation data

3D Viewer#

The 3D Viewer provides interactive, real-time visualization of Tidy3D simulations directly within your IDE. It automatically detects simulation objects in your code and opens alongside your editor, providing immediate visual feedback as you develop.

Key Features:

  • Automatic Detection – Identifies Simulation objects and opens automatically

  • Live Synchronization – Updates instantly when you modify code

  • Interactive Navigation – Rotate, zoom, and pan to explore simulations

  • AI-Controlled – FlexAgent can navigate and explain the 3D scene

  • Comprehensive Visualization – View structures, sources, monitors, and boundaries
