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.

ESP32 iPhone Agent runs on an ESP32-S3 that presents itself to an iPhone as an AirPlay receiver, a USB mouse and a USB keyboard. A vision model watches the mirrored screen and taps, swipes and types through AssistiveTouch on an unmodified phone. README photos show the board and phone setting a repeating alarm in the Clock app.

Clawdmeter shows Claude Code session and weekly usage limits on an ESP32 display board, where a Clawd character reacts to prompts. Through Claude Code hooks it flags sessions waiting for input. It pairs over Bluetooth, and its buttons send key presses. The README lists 8 supported boards and 15 community ports. A photo shows two devices running.

m5-paper-buddy pairs firmware for an M5Paper V1.1 e-ink board with a Python daemon that mirrors running Claude Code sessions. The screen shows each session's project, branch and context use. Pending tool calls appear full screen, and the board's buttons approve or deny them. It connects over USB serial or BLE. A README photo shows the dashboard on the board.

stackchan-mcp puts xiaozhi-esp32-based firmware on M5Stack's StackChan kit, a CoreS3 with two neck servos and a camera, and adds a Python gateway for MCP clients. Claude Code or Claude Desktop can move the head, take photos, read the touch sensor and switch the avatar's expression over WebSocket. The README shows no photos of the robot.

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.

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.

cardputer-claude-mcp runs a MicroPython app on an M5Stack Cardputer-Adv, linked over BLE to an MCP bridge on a Mac. Claude Code pushes notices, questions and a usage dashboard. A hook routes shell commands and file edits to the device; routine ones pass, ordinary ones need Enter, and destructive ones such as git push need Y. Photos show both prompts.

OnlyClaws ESP is ESP32 firmware that an agent programs over HTTP with Lua scripts after a single flash. The scripts draw on the panel, play audio, read sensors and report events; a classic-ESP32 build drives a Waveshare RoArm-M2 arm. The README's demo GIF and video show apps on an ESP32-S3 board; the three-app hero image is simulated.

Beee puts an animated face on a Waveshare ESP32-S3 touch screen that agents reach through an HTTP API or an MCP server. An agent can show moods and short text, or ask a question and wait until a person taps an answer. Critical actions get a flashing red border and a countdown. README photos show the face on the device.

Nod answers Claude Code permission prompts from a 3-key pad built on a Seeed XIAO ESP32-S3: No, Always and Yes. The keys send the desktop app's shortcuts or, after a two-key hold, the terminal's numbered options. It works over USB-C or Bluetooth. The author says the Clawd-shaped variant was tested on hardware; the README shows renders, not photos.

benchmux holds a board's USB serial or BLE link and logs its output to a file that agents and people can follow. Flash and reset commands release the port and reattach without stopping the monitor. It installs as a Claude Code skill. Aaron Perkins lists ESP32 as the only tested target, and the serial tool does not run on Windows.

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.

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.

BREMA is busware firmware for its TUL KNX stick that answers MCP over plain HTTP on the local network. An agent can address a factory-fresh KNX actuator, write its tables and parameters and add it to Home Assistant without ETS. The README says the commissioning example ran on hardware but shows no photos or logs.

FTC Toolchain gives coding agents 35 MCP tools for building and deploying FIRST Tech Challenge robot code. It searches FTC SDK samples and Pedro Pathing docs, scaffolds OpModes, builds TeamCode with Gradle, deploys to a REV Control Hub and reads robot logs. It installs with npx; the README calls its npm tests a smoke test that needs no robot.

smarthome-builder-mcp exposes a Home Assistant installation, including its Node-RED flows and ESPHome devices, to an AI assistant as 51 MCP tools. For ESPHome devices it edits and validates YAML, compiles, flashes over the air and reads logs. It backs up every change first, previews writes as a diff and always asks before flashing. The README calls it alpha.
