Toit MCP

IoT Free Open Source

Program ESP32 devices with AI via MCP. Write Toit scripts, manage device fleet, monitor sensors, and deploy OTA updates.

What is Toit MCP?

Toit MCP connects AI assistants to the Toit IoT platform. Toit provides a high-level programming language and cloud platform specifically designed for ESP32 microcontrollers — making IoT development accessible and maintainable.

Toit Language Support

AI models can generate Toit language code that follows the platform's conventions, using the correct sensor libraries, network APIs, and device management patterns.
