Nordic Semiconductor's Bluetooth Low Energy chips (nRF52, nRF53, nRF54), usually built with the nRF Connect SDK on Zephyr.

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.
Ranked by points weighed against age. New entries with early votes rise.

In September Nordic Semiconductor added skills to its Nordic MCP server that drive a Power Profiler Kit II and SEGGER J-Link probes. The PPK2 skill captures long measurement runs and flags anomalies against a reference pattern; the debug skill runs GDB sessions. The nRF Connect extension for VS Code now shares build context. The post shows no runs.

Adsum Networks' IoT Coder agent debugged a Fanstel BWG840 gateway whose nRF52840 BLE scanner ran cleanly but received nothing. It flashed an nRF52840 dongle as a Bluetooth sniffer and compared the air with RTT logs: 36 advertisements captured, none received. The cause was an RF front-end that was never enabled. This is a vendor demo of its own product.

Daniel Frassinelli of Veecle reviewed first-party hardware MCP servers and found that seven chip and tooling vendors shipped them between October 2025 and August 2026. He found no official server from ST, Infineon or Renesas. He writes that none of the vendor servers runs firmware without a physical board; Veecle's own product, Chiplab, targets that gap.

Nordic Semiconductor released 2 MCP servers that connect coding assistants such as Claude Code to its SDK and cloud. The Nordic MCP server adds documentation search, an nrfutil reference, a UART monitor script and SDK workflow commands. The nRF Cloud server reads fleet data such as logs and coredumps, without write access. The post shows no hardware runs.

Adsum Networks set Claude Code with Nordic's MCP on a BLE bug where data flowed one way between nRF52 and nRF53 boards. Running Claude Haiku 4.5, it guessed at fixes from the source and looped without solving it. Adsum's own IoT Coder, on the same model and with live logs from both boards, found the boards' roles were inverted.
