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.

Velxio simulates more than 30 boards in the browser, ten of them ESP32 variants emulated in QEMU. Its AI agent, on paid plans, wires parts on the canvas, writes the firmware, compiles it and reads the serial monitor. All of it is simulation; creator David Montero Crespo writes that the build is the binary you would flash.

Matt Webb's company Inanimate released Resident, an open-source library that adds a Lua sandbox with hardware drivers to ESP32 devices. Apps arrive over Wi-Fi and hot-load without reflashing. Bundled Claude skills create, validate and push apps to a device such as the M5StickS3. Webb writes that sandboxed apps get buttons and screens but not the network stack.

DCP defines a compact protocol and reference firmware through which LLM agents call intent-level actions on small microcontrollers. A host-side bridge exposes each intent as an MCP tool and checks capability tokens, units and ranges before anything reaches the board. The README lists 13 of 13 round-trip tests passing on an ESP32-WROOM-32 and an ESP32-S3.

awesome-mcp-hardware lists MCP servers and clients for hardware and the physical world on GitHub. About 22 entries cover debug servers for probe-rs, TI XDS110 and STM32, serial and TCP bridges, a Saleae Logic 2 server, a ROS server and Modbus and OPC UA servers. New entries arrive through pull requests.

rttsh is a Windows command-line terminal over SEGGER J-Link RTT for checking firmware on the board. Firmware exposes a command console through RTT, and Lua scripts on the host send commands and assert on replies and timing. It shares the flashing probe, leaves the UART free and includes an 8-tool MCP server. The README's 23 example scripts target an STM32H743.

claude-code-eyes grabs one frame from an Android IP Webcam, a Raspberry Pi camera or any snapshot URL and hands it to Claude Code. Version 1.1 added lens zoom for reading small markings. The README's demo shows Claude flashing an ESP32 over OTA and fixing a display bug its tests missed.

STM32 AutoDebug Universal Kit compiles STM32 firmware with Keil MDK, flashes it over SWD and waits for a pass token on the serial port. On a HardFault it reads the fault registers and maps the PC to a source line. Every result is an exit code. It is Windows-only; the README shows example output from an STM32F103C8T6.

AIX Skills collects 76 agent skills for embedded work, from 8051 and Cortex-M debugging to CANopen and cellular AT modems. Each skill gives an agent trigger conditions, a step-by-step workflow and checks, and the repo adds templates for writing new ones. The skills are instructions only, and the README shows no runs on hardware.

ESPHome-MCP connects an agent to the ESPHome Device Builder through the WebSocket protocol it adopted in 2026.6. Its 16 tools edit and validate YAML, stream logs, decode crash backtraces and compile and OTA-flash firmware. Flash tools are marked destructive, and an offline device reports a deferred flash. The author expects to archive it once ESPHome ships its own MCP server.

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.

QClaw runs a Qwen3.5 0.8B model and a Go agent loop on the Linux side of an Arduino UNO Q board. Its 8 tools include camera capture, I2C scans and sketch compiles that OpenOCD flashes to the board's MCU over SWD. David Laurenvil says it scrolls text across the LED matrix offline; we have not seen photos or logs.

In Silico, coding agents write and maintain a device's firmware from a spec kept in a GitHub repo. The agent scaffolds firmware, a simulator with its own HAL, an install tool and CI that runs on the simulator and on hardware. MicroPython is the default, with C on ESP-IDF as an option. Three demo specs target an M5Stack M5GO kit.

AURIX AI Agent connects GitHub Copilot's agent mode in VS Code to Infineon AURIX iLLD drivers, code examples and documentation through MCP. Copilot then builds with GCC and flashes the board with AURIX Flasher. The author's linked videos show a one-sentence prompt blinking every LED on a TC387 and a pose-detection game on a TC375. The extension is Windows-only.

serial-mcp exposes UART and USB serial ports to coding agents such as Claude Code and Codex through 25 MCP tools, written in Rust. An always-on receive buffer answers reads with pattern matching instead of blocking. A boot-capture tool pulses DTR or RTS for Arduino auto-reset, and port allowlists limit what the agent can open. The README shows no board logs.

Firment is a Rust coding agent for firmware that builds with the project's own toolchain and flashes and debugs over probe-rs. The README ranks evidence: a photo of a lit LED or a logic-analyzer capture outranks the model's word. A red-team mode fuzzes the UART of firmware the agent wrote. The README shows client screenshots, no hardware run.

esp32-ai-loop-mcp-server gives Claude Code 11 tools to build an ESP-IDF project, flash it to an ESP32 and read the serial output. The serial monitor runs in a background thread, writes to a log file and releases the port while flashing. The agent searches the log after each change. The README shows an example session but no captured device logs.

McuBuddy connects AI assistants to MCU debug probes such as ST-Link and J-Link for board-level debugging. Opt-in toolsets add Keil MDK builds, SVD register decoding, RTT and UART logs, FreeRTOS task state and flash writes. Each result says what kind of failure it found and suggests the next safe check. The README lists validation on STM32L496 and STM32F103 boards.

OpenBaud connects Codex to local serial devices through an MCP server and plugin, with every write audited. It identifies ports from USB metadata, checks framing and checksums, and asks for acknowledgment before dangerous commands. Each byte goes to a capture that replays without hardware. The demo GIF and 46-second video show it on an ESP32-S3.

vibe-hardware installs skills into Claude Code or Codex that take an idea to ESP32 firmware, a KiCad board, a build123d enclosure and a JLCPCB order. Its example is a desk pager on an M5StickC S3 that buzzes when a Claude Code session needs input. The README says the firmware works; the PCB and shell are still stubs.

embedagents-stm32 runs ST's own command-line tools from Claude Code to work on STM32 projects. It drives CubeMX, CubeIDE, CubeProgrammer, the signing tool, the ST-LINK GDB server and the virtual COM port, and bundles none of them. The README's demo GIF shows Claude Code building and flashing a NUCLEO-L476RG from one plain-language request.
