platformio.mcp: PlatformIO build, flash and serial tools for coding agents

platformio.mcp exposes PlatformIO to coding agents as 40 MCP tools in a Python server. Besides builds and serial or OTA flashing, it decodes ESP32 and Cortex-M crash backtraces, reads core dumps, checks partition tables and runs GDB sessions. Its flash-and-verify tool reads the boot log until an expected line or a crash appears. The README shows no board captures.

Briefing

pio_flash_and_verify ends one of three ways: the expected string appears and the run passes, a crash signature such as a Guru Meditation or HardFault appears and is decoded to a file and line, or the read times out. The 40 tools fall into 10 groups and install with one uvx command for Claude Code, Cursor, Codex, Windsurf or Claude Desktop.

Optional extras add the ESP32 core-dump analyzer and a driver for Nordic's PPK2; the power-profile tool also reads a serial INA219 meter. Three policies limit what an agent may do: full, build_only (no flashing or serial writes) and read_only.

The README credits jl-codes/platformio-mcp, a TypeScript server, as prior art. Its sample session is an example transcript, not a capture.
