Repos, MCP servers, CLIs and libraries that connect an AI agent to boards and bench gear.
Most GitHub stars first. Tools without repo facts come after, newest first.

mcu-skills packs per-board knowledge for Claude Code into 21 skills, from the WeAct Black Pill to the Waveshare ESP32-C6-LCD-1.47. Each holds pin functions, working clock trees, HAL calls that fail silently and how to flash the chip. The README says each skill's template project builds. It reports no tests on hardware.

Seeed Studio's XIAO Assistant answers coding agents' questions about 17 XIAO boards over MCP, from pin maps checked against the wiki to deep-sleep current. Its 12 tools also search 64 Arduino, MicroPython, CircuitPython and Zephyr examples and compile sketches. The same data ships as a CLI and an SDK. The README describes no flashing of a connected board.

FreeOCD flashes, verifies, recovers and soft-resets microcontrollers from VS Code through a CMSIS-DAP probe, and opens a two-way SEGGER RTT terminal. The extension registers the same actions as MCP tools for Copilot and other MCP clients. The README lists the Nordic nRF54L15 as the only built-in target; other chips need a target definition file.
