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.

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.

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.

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.

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.

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.
Ranked by points weighed against age. New entries with early votes rise.

A Reddit user had Claude Fable 5 design an RP2350 e-ink board through a KiCad MCP server, allowing no manual edits. Wccftech reports several rounds to fix wrong part picks. Five assembled boards cost 130 euros plus $450 in API credits, and Claude Opus 5 wrote the firmware. Photos show the board driving its 1.54-inch display.

Anthropic opened a research preview of the Model Hardware Standard, a shared driver spec for agents that operate lab and manufacturing devices. Each device describes its settings and enforced safety limits, and agents reach it over MCP, a CLI or code. In a QuEra case study, an agent-improved laser relock script worked in 99.3% of 700 trials.

Tal Raviv connected Claude to a SunFounder PiCar-X through a terminal on its Raspberry Pi, with camera photos as feedback. The robot saved notes, learned gentler turns and a three-point turn, and spent about 15 minutes parking at a filing cabinet instead of 20 cm from the door. The post embeds an edited demo video.

Amer El-Saad built a 3-DOF tower crane for his master's thesis that Claude plans and drives through 4 MCP tools. One overhead camera, YOLOv8 and ArUco markers locate parts and stations in centimeters. An Arduino Uno drives the DC motors, and code rejects any route that crosses a worker. README photos show the crane and live detections.

Synacl's 2.5-minute video shows claude.ai writing a macro that runs on an ESP32 flashed with Synacl's gateway firmware. Claude connects through a custom MCP connector, creates a GPIO device and writes a 5-step macro. Its first run is refused until a person grants 2 permissions; then the board's GPIO 2 LED blinks. Synacl made the demo for its own product.

Anthropic's red team had Claude, GPT, Gemini and other models drive robots, mostly in simulation plus a real Unitree Go2. The team reports that Opus 4.6 misjudged where a trash can was and the Go2 dragged it. Grok 4.1 Fast headed for a table reflected in a glass door, and no model completed an office loop on vision alone.

Cliff Lasser built a clock from 128 Soviet IV-25 VFD tubes on eight boards, each run by an Arduino Nano ESP32 over RS485. He wrote about 15 pages of specification, and Claude wrote all the code, now over 8,000 lines. The first version, about 3,500 lines, ran on the first try with one bug: the display was rotated 180 degrees.

Tech-AD-venture's 23-minute video walks through using AI agents in VS Code for STM32 firmware, contrasting autocomplete with task-based agents. Tools covered include GitHub Copilot, Claude, Codex and PlatformIO. An STM32 RTOS example runs from requirement to review. Its description lists MCP hardware access as a possibility; we could not confirm on-board debugging in the video.

Marcel Dütscher and his 10-year-old son built Pixel Pets, virtual pets for three M5Stack boards, with Claude writing the firmware under their direction. The CoreS3 version adds voice control through M5Stack's Module LLM, and pets swap gifts over ESP-NOW. Photos, a 10-second clip and a two-minute reel show the pets running on the devices.

Zhihan Zhang and colleagues, mostly at the University of Washington, published Embedded Arena, a benchmark that scores agents' model and firmware edits on microcontrollers. Boards include a MAX78000, an ESP32-S3 and an STM32N6. The paper reports Claude Opus 4.7 and Gemini 3.1 Pro failing every deployment without hardware feedback; with it, the first success came within 3 iterations.

The atopile team published EEBench, a benchmark that grades agents on 13 circuit-design tasks written in atopile. The harness builds each design and runs SPICE checks at worst-case tolerance corners. The post says Claude Opus 5 led V1 at 61.6%. One failed design used a 22 uF capacitor that gave about 11.4 uF under bias. V1 is simulation only.

XDA's Adam Conway ran the same ESP32 wiring prompt 15 times across Claude Sonnet 5 and Opus 5. With a vague prompt, Sonnet put a display's DC line on strapping pin GPIO2 in 3 of 6 runs, twice after naming the rule. Opus never did, though one run misstated the rule. He writes that naming the exact board helped both.

Alice Plante had Claude write the code and choose actions for a SunFounder PiCar-X on a Raspberry Pi 5 and a FrodoBots Earth Rover. The Earth Rover's commands went through a cloud relay while Opus took about ten seconds to answer, and it drove into trees. A small binary on the rover cut command latency to under 10 ms.

Arduino released App Lab 0.10 with Agentic Mode, which connects a bring-your-own-key model to an UNO Q project through MCP and the App CLI. Claude is the first supported provider. The agent can create and edit files, run and stop the App and read errors as they happen. The post does not show it reaching the board's pins directly.

Flux added a public MCP server to its PCB design tool in its summer update. External agents such as Claude, Cursor and Codex can query a board's live context and drive design changes. The post gives firmware headers generated from actual pin assignments and net names as one use. The update also adds a lower-cost chat mode.

Dave Vandenbout ran his datasheet-to-symbol-lib Claude skill on 100 parts with 20 or more pins and diffed the results against KiCad's stock symbols. With every difference checked against the datasheet, generated symbols had a 2.77% pin error rate and the library 21.92%. The README notes that the same agent generated the symbols and judged both sides.

Researchers had coding agents write robot behavior trees from a contract served by a robot-side MCP server. The contract lists the robot's skills, allowed operators and optional templates, and a gate validates each tree before it runs. The paper reports tests of Sonnet 4.6 and Gemma4:31b on 110 simulated tasks and 14 on a Husarion Panther running Nav2.

In a German video, Stefan Draeger compares Claude Code with the Claude.ai chat on an Arduino UNO R3 and an ESP32-C3 Super Mini. Claude.ai writes a sketch inside the chat, while Claude Code works on a project's files directly. Draeger says generated code still has to be checked and tested. A blog post goes with the 7-minute video.

A software engineer had Codex with GPT-5.5 write most of wfb-link, a Rust stack that drives an ALFA AWUS036ACH Wi-Fi adapter from macOS userspace. Claude Opus 4.7 helped at times. The stack initializes the RTL8812AU and sends and receives WFB-NG frames, with a Raspberry Pi 5 at the far end. The Show HN post says the alpha took two weeks.

Espressif published a recap on 14 May of ESP32 projects from Anthropic's Code with Claude event, where each attendee got an ESP32-S3 M5Stack Cardputer. Attendees described a program in plain language, and Claude Code wrote and flashed it. The post also covers Claude Desktop Buddy, a BLE reference design on the M5StickC Plus, and Espressif's own ESP Desktop Buddy library.
