}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Crosspad MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (4.0.1) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

crosspad-mcp

Talk to your CrossPad. Let Claude do the toolchain.

crosspad-mcp is an MCP server that teaches Claude Code (or any MCP client) how to develop for the CrossPad pad controller. You say *"flash the new build and check that it boots"*; it runs the ESP-IDF build, asks you to confirm the flash, opens the console, runs the smoke scenario and tells you what happened — with the hardware traps already built in, so you don't have to remember which serial port reboots the board when you open it.

What you can do with it

Every card is a real prompt. The tools named underneath are what runs — you never have to call them yourself.

Say this…	…and this happens
"Build the firmware and flash it over OTA."	`crosspad_build platform=idf` streams the build, `crosspad_flash transport=ota` asks for confirmation, then streams the upload. New app directories are detected and the `fullclean` is done for you.
"Show me what's on the simulator screen."	`crosspad_run` launches the PC sim, `crosspad_screenshot` returns the LCD as an image Claude can actually look at. Then "press pad 5", "turn the encoder left twice" — `crosspad_input`.
"Play a drum pattern on the pads and record what comes out."	`crosspad_stimulus` hits the pads with real timings, `crosspad_capture` records the board through its own USB-audio endpoint, `crosspad_analyze` gives a verdict (onsets, clicks, silence, velocity curve).
"Why did it crash?"	`crosspad_diagnose_crash` — reset reason, registers, backtrace decoded against the ELF that is actually flashed, heap after restart. One call.
"Watch the battery charger state machine while I plug the cable in."	`crosspad_trace` polls STM32 variables live over ST-Link without halting the core, and plots them.
"Install the sampler app and rebuild."	`crosspad_apps_install app_name=sampler` adds the submodule from the crosspad-apps registry, then a clean build.
"Where is `IPadLogicHandler` implemented?"	`crosspad_interface_implementations` across every repo of the ecosystem, or `crosspad_symbol` for clangd-precise definitions and call hierarchies.
"Is my board even connected?"	`crosspad_devices` and `crosspad_doctor` — which USB mode it is in, which ports belong to it, what is missing on the host, and how to fix each thing.

Quick start

claude mcp add crosspad -- npx -y crosspad-mcp-server

Restart Claude Code, then ask:

*is my CrossPad connected, and is the toolchain set up?*

That runs crosspad_doctor. Every failed check comes with a fix. The server assumes your repos live side by side under ~/GIT/ — if they don't, set the paths once.

Installing the bundled crosspad skill gives Claude the ecosystem map, the per-role guides and the hardware traps up front:

/plugin marketplace add CrossPad/crosspad-mcp

/plugin install crosspad@crosspad

How it is organised

Only the core toolset is visible when the server starts, so the tool list stays small. Claude enables the others as the conversation needs them — or you start the server with --toolsets device,sim.

flowchart LR

core["core · always on devices · doctor · snapshot build · flash · repo status · tasks bench lease"] sim["sim PC simulator: run, screenshot, input, MIDI, settings, tests"] device["device the board over USB: console, CDC verbs, UI driving, USB mode"] hil["hil scenarios, pad stimulus, audio capture + analysis, BLE"] code["code symbols, interfaces, docs search"] git["git submodule drift, update, commit"] apps["apps crosspad-apps registry"] trace["trace SWD live variables"] core --> sim & device & code & git & apps device --> hil core --> trace

Anything that writes to a device or your host is tiered. Flashing, DFU and SWD writes come back as *confirmation required* first; --read-only removes every writing tool from the list entirely. Long operations (builds, flashes, scenarios) run as tasks you can check on, wait for or cancel.

Who is it for

You build and drive CrossPad firmware — mostly the simulator, sometimes the board. Start with the user guide.
You work on the firmware itself — flash, console, HIL scenarios, crash diagnosis, SWD. Read the firmware developer guide and HIL testing.
You want to extend this server — the contributor guide and the Development section.
