ESP32 MCP Server

Example Use Cases

• 1

  Query and monitor real-world sensor data from I2C devices.

• 2

  Decode and interact with marine and vehicle bus protocols like NMEA 0183, NMEA 2000, and OBD-II CAN.

• 3

  Access historical bus data and metrics for diagnostics or automation.

Description

ESP32 MCP Server implements the Model Context Protocol (MCP) on ESP32 and Nordic nRF52840 hardware, providing real-time access to sensor data and vehicle/marine bus protocols such as I2C sensors, NMEA 0183, NMEA 2000, and OBD-II CAN frames. It enables AI agents and automation tools to query and subscribe to hardware sensor data and bus histories via a standardized JSON-RPC 2.0 interface over WebSocket. The server supports multiple boards, offers a web dashboard, and includes features like WiFi setup, discovery, metrics, and persistent bus history buffers.
