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.

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.

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.

MCP-AmigaOS4 drives AmigaOS 4.1 machines through 138 MCP tools and a daemon on each Amiga, on QEMU guests and real PowerPC hardware alike. Tools edit files, run AmigaDOS commands, take screenshots and install the OS. On an AmigaOne X5000 it reads sensors through the board's MCU and switches power over an FTDI cable. The README says both targets were verified.

labgrid-mcp puts a labgrid hardware lab behind 47 MCP tools, from reserving a board to switching its power and reading its serial console. SSH commands and, when enabled, flashing are also covered; flashing and other irreversible actions are off by default. The README's demo GIF shows Claude driving the built-in fake lab, with no hardware attached.

Jacob Beningo's devusb switches, monitors and power-cycles USB ports from a CLI or an MCP server. It drives Yepkit YKUSH hubs over HID and other switchable hubs through uhubctl. When a probe or board hangs, the agent cycles its port instead of asking for a replug. The README marks the YKUSH3 and two generic hub chipsets as verified on hardware.

Atilla Basut, a computer science student, built three pieces that help Claude write STM32F4 firmware. A MISRA-C review skill checks code, and an MCP server searches the 1,700-page RM0090 reference manual and lints register writes. A serial MCP server and HIL runner flash an STM32F4-DISCOVERY and run UART tests. The README says it was checked on that board.

ae-hw-bridge connects AI agents over MCP to a target board through HW Puppet, MicroPython firmware for an ESP32-S3-DevKitC-1. Over one USB cable, HW Puppet drives the target's reset, boot and power lines and bridges its UART console. A mirrored terminal shows a person the same log the agent reads. Neither README shows a recorded run.

Jacob Beningo's devpsu sets voltage and current, switches the output and power-cycles a board from a CLI or MCP server. It supports three B&K Precision 168xB models and Manson HCS-3xxx supplies. Session limits come from the user through an MCP prompt; environment ceilings refuse anything higher. The README says it was built against a 1687B.

bus-mcp runs on a Raspberry Pi and exposes CAN, CAN-FD, RS-485, UART, I2C, SPI and GPIO as 18 MCP tools. Buses are read-only until writes are enabled for chosen bus kinds. An installer sets up a systemd service with an HTTP endpoint. The README gives a loopback test procedure but no recorded results.

flashgate checks whether firmware an agent just built runs on an STM32 board. It flashes over ST-Link, waits for a boot banner carrying the git hash, drives features over the console and checks register readbacks. Each run ends with an exit code and a JSON record. The README includes console output from an STM32H743 bench.

ESP32 MCP IO Extender runs on an ESP32 and exposes its GPIO and UART pins to a host over USB serial for automated tests. Commands travel as JSON lines from a Python library, a CLI or an optional MCP server. Firmware enforces a pin safety policy, and named endpoints map pins to roles. The README shows no run logs.

espforge packages the ESP-IDF v5.5.4 framework and working method its author used to build an ESP32 weather display with Claude Code in 6 days. Its firmware components handle Wi-Fi setup and over-the-air updates with rollback. PC tools flash, probe, screenshot and test the board without a person. The README shows no recorded agent runs.

EmbeddedCI's BenchPod plugins connect Claude Code and Codex to a BenchPod, the company's hardware-in-the-loop tester wired to the board under test. One MCP server has tools to flash over SWD, power-cycle and capture the boot log, emulate I2C sensors, capture logic and analog signals and talk CAN. The vendor README lists the tools but shows no runs.

SAIHub firmware runs on an ESP32-C5 and serves MCP over Wi-Fi to coding agents such as Cursor and Claude Code. Agents can drive eight GPIO pins, generate PWM up to 50 kHz, capture edges, use a UART, switch 3.3 V and 5 V rails and run Lua scripts on the board. The README shows no photos or test results.

Agent Debug Probe connects a coding agent to a target through an RP2040 probe and MCP adapter. The agent can switch target power and USB data, drive reset and boot straps, and use SWD/JTAG and UART. A validation report dated 8 August logs bench tests of the fabricated board, including an 8.66 MB UART transfer to a Zynq target.

Agent Fingers runs on a stock Raspberry Pi Pico 2 as a signal instrument and CMSIS-DAP debug probe for AI agents. It offers eight digital channels, ADC capture, PWM, UART, I2C and SPI, plus SWD and JTAG for STM32 and ESP32 targets. Outputs need an expiring arm lease. The README shows no hardware runs.

TatraSpace demos WisentWire, its hardware-in-the-loop test rig, on a small sumo robot. In the 4-minute video the team reserves the rig, flashes firmware, sends commands over UART and logs power, then uploads faulty firmware and the robot hits the wall. The video drives everything from the GUI; TatraSpace says its MCP server reaches the same functions.

Agentic HIL exposes MCP tools that flash a board through OpenOCD, pyOCD or STM32CubeProgrammer and drive it over UART and CAN. Each action is checked against one bench configuration kept outside the repository, and a pytest plugin runs the same gate in CI. Hannes Pauli's worked example targets an ST Nucleo-F446RE. We have not seen run logs.
