Briefing
The firmware serves Streamable HTTP MCP at /mcp on port 80 and runs on any ESP32-C5 board. The project's own SAIHub-Mini is 48 x 28 mm with USB-C, a BOOT button, a 12-pin header and a U.FL antenna, and its KiCad files are in the repo. Pins support open-drain output and pulses, edge capture runs for up to 60 seconds, and the Lua 5.4 runtime is sandboxed.
The power rails start switched off, and logic is 3.3 V only. Besides MCP, the board offers REST with an OpenAPI description, and Codex CLI is named alongside Cursor and Claude Code. It connects over the LAN, a self-hosted Cloudflare relay or a managed relay. The code is MIT licensed.
