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.

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.

AI Desk Card, a skill for Claude Code and similar agents, sets up an M5Paper V1.1 e-ink panel as a desk display. The agent installs PlatformIO, flashes the font and firmware, starts a local daemon and sets up Wi-Fi. Widgets range from weather to a pull-request queue. The README has a photo of the panel on a desk.

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.

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.

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.

wirestudio generates pin assignments, ESPHome YAML, a KiCad schematic and PCB, a JLCPCB fab bundle and an OpenSCAD enclosure from one design file. It covers ESP32-family boards and the ESP8266. A built-in Claude agent or any MCP client can call its 53 tools, 22 of which reach hardware. The README says those were exercised on a live bench during bring-up.

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.

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.

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.

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.

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.

platformio.mcp exposes PlatformIO to coding agents as 40 MCP tools in a Python server. Besides builds and serial or OTA flashing, it decodes ESP32 and Cortex-M crash backtraces, reads core dumps, checks partition tables and runs GDB sessions. Its flash-and-verify tool reads the boot log until an expected line or a crash appears. The README shows no board captures.

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.

esparagus is a Rust port of esptool that reports to programs instead of people. It emits NDJSON events, a JSON report of suggested next steps and a fixed exit code per failure class. A monitor watches the boot log for crashes and reboot loops. Sylwester Sosnowski reports full bench validation only on an ESP32-P4.
