MCP server brings structured compile, flash and stateful GDB to embedded boards
Historical_Court795 · reddit · 2026-08-04
- The author built an MCP server for embedded software that exposes compile, flash, and serial workflows as structured tools.
- The key design choice is returning machine-readable JSON from compile() instead of scraping CLI stdout for status.
- It also supports a stateful debugging session over MCP: debugstart, setbreakpoint, getcallstack, getregisters, and step can drive a persistent OpenOCD + GDB session across multiple calls.
- The project is board-universal through PlatformIO (about 1,000 boards), works both as a CLI and as an MCP server, and is MIT-licensed.
- The author is explicitly asking for feedback on the tool schema design, especially for the newer OTA/fleet side.
