# Device Context Protocol

> Use this tool when you need to control and interact with IoT microcontrollers, such as ESP32 devices, in real-time, and require a standardized protocol for efficient communication over constrained networks. It solves problems of device control and data exchange in edge computing environments, providing a bridge between Device Context Protocol (DCP) and MCP. The tool takes CBOR-formatted input and outputs real-time control commands for physical devices.
