Use cases
Real accounts of agents doing this kind of job, each linked to its source.
- Get a costume prop built after ChatGPT points you to a hackerspace
ChatGPT told someone building an Escape from L.A. wrist timer to visit the Denver hackerspace. A member ended up sourcing parts, ordering a custom PCB and printing the case for him.
- Have Claude build parts in an open-source parametric CAD tool
The author of Lobole, a parametric B-Rep CAD app, found Claude good at driving it through scripts; the engine, watch and bicycle shown in the README were each built by Claude.
- Design an ESP32 WiFi fan controller in KiCad with Claude
A PCB designer with 40 years' experience asked Claude Opus 5.5 for the schematic and ESP-IDF firmware of a WiFi fan speed controller; it finished in about 20 minutes. Claude also drew a board outline from photos of the case and caught issues in his mains-voltage layout.
- Design a 5A buck converter board with Claude Code and KiCad MCP
A JLCPCB walkthrough used a KiCad MCP server with Claude Code to draw the schematic and lay out an XL4015 buck converter, then covered ordering, with a reminder that the design still needs an engineer's check.

Questions people ask
How many make things MCP servers are there?
This directory lists 30 make things entries: 25 MCP servers and 3 APIs, plus 2 with other access. We counted them on November 1 and 2, 2026.
What is the most popular make things MCP server?
By GitHub stars, kicad-mcp-server leads with 176 stars as of November 1, 2026. Stars show interest, not quality, so check when it was last updated.
Which make things servers are official?
9 come from the vendor or project they control: kicad-mcp-server, heypcb-mcp, Agentic Fabrication Network (AFN), JLCPCB, Moonraker API (Klipper) and OctoPrint REST API.
Which ones work without an API key?
9 need no key, based on their docs: kicad-mcp-server, Moonraker API (Klipper), freecad-mcp, easyeda-agent, kicad-mcp-pro and fusion360-mcp-server.
Is it safe to let an agent control real devices?
Only give an agent the access you would give a person. Start with read-only tools, keep a person in the loop for anything that moves, prints, sends or spends, and read each project's README first.
