[Boston, Nov 12, 2025] — Flexcompute is excited to announce the release of FlexAgent MCP, a new AI-powered simulation assistant that can build, iterate, and visualize electromagnetic models with unprecedented ease. This launch marks a major milestone in photonic design, enabling fully AI-assisted simulation through a code-free, natural language–aware workflow.

What is FlexAgent MCP?

FlexAgent MCP is a physics-informed AI assistant that integrates the Tidy3D Model Context Protocol (MCP) with platforms such as Cursor, VS Code, and additional MCP-compatible environments. Through the Tidy3D extension, users can interact with simulations entirely via natural language: exploring examples, generating new models, modifying setups, and visualizing results—all without writing a single line of code.

Watch the demo to see how the FlexAgent MCP Tidy3D extension performs a mode analysis step-by-step.

What Makes FlexAgent MCP Unique?

• AI-Enhanced Workflows — Agent assistance powered by integrated Tidy3D expertise through the MCP server

• Structured Guidance — Step-by-step support spanning learning, setup, refinement, and optimization

• Trusted Knowledge Base — Direct access to the full, always-current Tidy3D documentation

• Editor-Native Viewer — Visualize simulations right inside your IDE, with zero context switching

• Live Code Synchronization — Real-time geometry and simulation updates as you edit

• AI-Controlled Visualization — Let the agent navigate, annotate, and explain the 3D scene for deeper insight
