An MCP server implementation on the W600 microcontroller enabling vehicle diagnostics via ELM327 OBD-II interface over HTTP.
Query vehicle diagnostic data remotely via HTTP.
Read and interpret OBD-II diagnostic trouble codes.
Perform vehicle diagnostics using the ELM327 protocol on embedded hardware.
This project implements a Model Context Protocol (MCP) server running on the W600 WiFi SoC, providing vehicle diagnostic capabilities through an ELM327 OBD-II interface. It supports communication over HTTP using JSON-RPC 2.0, allowing AI agents and clients to query vehicle data, read diagnostic trouble codes, and perform OBD-II operations wirelessly. The firmware includes features like OTA updates, WiFi connectivity, and a built-in OBD-II simulator for testing without a vehicle connection. It is designed as a technical challenge and learning project, not recommended for production use.
