Mokxi's MCP server lets an AI assistant build a whole project for you, board, parts, wires and code, check it the way the editor does, and hand you a link. Open the link and the project is laid out, wired and running in the editor. In 0.5.1 it works on every signed-in plan; in 0.5.0 it was Pro only.
To put the project on a real board, open the link and press Upload to board in the editor, then plug the board in. It writes the sketch over USB from Chrome or Edge on Arduino AVR boards (Uno, Nano, Mega, Leonardo, Micro and others) and ESP32-C3 boards; the Pico and other drive boards get a .uf2 file to drag on. The AI app itself cannot reach your USB port, so the upload is one press in the editor.
Set it up
The setup page is in the editor: MCP server under More from Mokxi in
the sidebar, at app.mokxi.com/tools/mcp. It is a short tutorial with three
steps, and the steps below are the same.
The server: the address to copy,
https://mokxi.com/mcp.Add it to your app. Pick your app, and follow its steps. Each has a Copy button.
- Claude or ChatGPT in your browser (the easiest). Sign in with Mokxi. There is no token. In Claude, go to Settings, then Connectors, then Add custom connector. Name it Mokxi and paste the address. In ChatGPT, go to Settings, then Connectors, turn on developer mode, and add a connector with the address. The first time the app calls a tool, a Mokxi page opens. Check the app's name and choose Allow.
- Claude Code, Cursor, VS Code (GitHub Copilot) and Gemini CLI. These
coding tools take an API token. Press Create API token in the
app's tab, copy the token, and paste it where the line or file says
mkx_your_token.
Try it. Start a new chat and paste one of these:
- Build me a traffic light with an Arduino Uno.
- Make an LED blink on an ESP32 and show me the wiring.
- Wire a potentiometer to an Arduino Uno so it dims an LED.
The AI builds the project and hands back a Mokxi link. Click it, and the circuit opens and runs in the editor.
Build Mokxi projects with AI has the same steps for more apps, and the full list of tools.

What it gives back
Only Mokxi's own results. The server reads the parts catalog, the boards and the templates the editor ships, and nothing else, and it tells your assistant to present Mokxi's answer as the answer: the project link first, the wiring summarized from the project, and only the pictures Mokxi returns, its own drawings of the circuit. It asks the assistant not to search the web for images or show stock photos, which show different hardware from Mokxi's.
The link carries the whole project after the #, which a browser never sends
to a server, so nothing is stored and your saved projects are not touched. The
project is yours to save once it is open, and anyone you send the link to opens
it with no account.
What each plan includes
- Free: up to 10 project builds a day through the server (each
create_project). The count starts again at midnight UTC. Every other tool, such as searching parts or checking a project, has no daily limit. Past the 10, a build answers with one line saying so, and for an adult's own account it adds Pro's price in your region and a link to get Pro. The setup page says the same in one line, with Upgrade beside it. - Pro, and every plan that includes Pro (the student price, Lifetime, a pass, a seat in a paid class and a Pro trial): no daily limit.
- A child's account, a class student and a class login: the server is not available, and the sidebar has no MCP server row.
Any app can connect and list the tools with no account; calling a tool takes a sign-in. Your API tokens and the apps you have connected (Connected AI apps) are under API tokens in Settings, where you can disconnect an app.
