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.

Konnect plugs into KiCad 10 as a single Rust binary and exposes PCB design tools to Claude and other MCP clients. Its 228 tools in 21 on-demand toolsets cover schematic capture, placement, routing, ERC and DRC, JLCPCB part search and manufacturing export. It succeeds the author's KiCAD-MCP-Server and is marked beta, with Windows the most tested platform.

quackd registers robots by name and has an LLM work toward a typed goal by calling one named skill per turn. Goals come from a terminal or from Claude over MCP, within step and time budgets, confirm gates and dry runs. The README lists eight robot bodies. Only a LeRobot SO-101 arm has run on hardware.

Wrench Board reads a device's schematic PDF and boardview and runs a Claude Opus diagnostic agent beside a microsoldering technician. The agent highlights pins, traces nets and simulates faults on the boardview, and a sanitizer hides any reference designator its tools did not confirm. The README says it placed second at Anthropic's Opus 4.7 hackathon in April.

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.

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.

K-Dense's LabMCP connects Claude and other assistants to lab instruments through 32 MCP servers. They cover balances, hotplate stirrers, syringe pumps, spectrometers, potentiostats and other instruments. Each server checks commands against user-set safety limits and logs them, and each has a practice mode. The README marks all 32 as tested only in simulation, from the makers' manuals.

sdr-mcp connects Claude Desktop or Cursor to an RTL-SDR dongle through a FastMCP server. Tools set frequency and gain, capture IQ samples, compute spectra with peak detection and keep a waterfall; FM audio plays through a GNU Radio demodulator in Docker. A React dashboard has the same controls. The README shows no captures from a dongle.

datasheet-to-symbol-lib has Claude read a component datasheet and build a KiCad symbol library through the kipart MCP server. It first writes each pinout, including alternate pin functions, to a JSON part description that a script checks. The README reports no errors in 245 pins across three test parts, against seven in KiCad's official symbols.

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.

ardupilot-mcp connects an agent to an ArduPilot vehicle over MAVLink. The agent reads vehicle state, gets and sets parameters, switches modes and reads prearm messages to see why arming failed. Actuation is off by default; a non-loopback link needs a second flag, and there is no force-arm. The README marks only ArduCopter 4.5 in SITL as validated.

klipper-mcp connects Claude or another MCP client to a Klipper 3D printer through Moonraker's HTTP and websocket APIs. Its 14 tools read status and history and control temperatures, prints and G-code; control tools preview first and act only when confirmed. A separate recorder logs how each print ended. The README names no printer it was tested on.

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.

efinity-mcp drives a local install of Efinix's Efinity FPGA toolchain from an MCP client such as Claude. Its tools create projects and compile them, set up I/O and PLLs, read timing and utilization reports, and program boards over JTAG or SPI flash. The README says an assistant-built LED demo ran on a Ti375 dev kit. Only Windows is tested.

moonraker-mcp runs next to Moonraker on a Raspberry Pi and exposes 43 tools for a Klipper 3D printer to Claude Desktop or Claude Code. Stop, pause, cancel and heater commands wait for a second call with confirmation; other G-code, including motion, runs at once. The README advises keeping the endpoint on a trusted LAN.

teensy-loader-mcp wraps PJRC's teensy_loader_cli in a Python MCP server for coding agents. Its tools check that the CLI is installed, list boards from the Teensy 2.0 to the 4.1 and MicroMod, flash an Intel HEX file and reboot a board. The README covers setup for Claude Desktop, Cursor and Grok, and recovery after a wrong-chip flash.

mcp-hardware-tools connects Claude to a Rigol DS1054Z oscilloscope and decodes SPI, I2C and UART from raw waveforms. Each capture comes back with clipping and trigger-status flags, and the agent adjusts the setup and captures again. The author reports bench tests against known signals from a JDS6600 generator and a Pico 2, and no use yet on an unknown fault.

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.

mcp-strumentazione connects Claude to a Tektronix TBS2204B oscilloscope over LXI and to an HP GPIB bench through 2 MCP servers. The bench server drives a 6632A supply, 6060B electronic load, 5334B counter and 3457A meter. The README includes measurements Claude took through them, among them a mains waveform and a lamp I-V sweep.

Logic Analyzer AI MCP connects Claude and other MCP clients to a Saleae logic analyzer through the Logic 2 automation API. Its 11 tools configure a Logic 8 or Logic Pro, run captures, add protocol decoders and export the data as CSV. Logic 2 must be running with its scripting socket enabled. The README shows no captures.
