Common questions

Is Tronbyt 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?

You need to fill in: TRONBYT_BASE_URL, TRONBYT_API_KEY

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 (0.1.0) reached the registry 4 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?

tronbyt-mcp

Let your AI assistant put things on your LED sign.

If you have a Tidbyt or Tidbyt-style LED matrix display managed by a self-hosted tronbyt/server, this connects it to Claude (or any other AI tool that speaks MCP, the open standard for giving assistants access to tools). Once installed, your display becomes something you can just talk to your assistant about:

"Put BREAD'S DONE on the sign in amber."

"Dim the display to 20% and turn on night mode from 10pm to 7am."

"What apps are on the sign right now? Disable the stock ticker."

"Show the clock app for a bit."

The assistant handles the rest — rendering text into the display's pixel format, talking to your server, managing the app rotation. Everything runs on your own machine against your own server; nothing goes through any cloud service.

How it works

tronbyt-mcp is a small MCP server that wraps tronbyt/server's documented REST API. Your MCP client (Claude Code, Claude Desktop, and friends) launches it locally and talks to it over stdio; it talks to your Tronbyt server over HTTP with a device API key.

Requirements

A display managed by a self-hosted tronbyt/server (v2.x). Any device the server manages works — it doesn't need to have started life as a Tidbyt: Tidbyt Gen1/Gen2, Tronbyt S3 and S3 Wide kits, MatrixPortal S3 (including the Waveshare variant), Waveshare S3, Pixoticker, Raspberry Pi displays, and homebrew panels typed "other". Both standard 64×32 and wide 128×64 (2x) panels are supported.
Node.js ≥ 20.9
An MCP client: Claude Code, Claude Desktop, or anything else that supports MCP stdio servers.

Installation

1. Get a device API key

In the Tronbyt web UI, open your device's settings and copy (or generate) its API key. Keys are scoped to a single device — one key, one display.

2. Add the server to your MCP client

Claude Code (one command):

claude mcp add tronbyt \

-e TRONBYT_BASE_URL=http://tronbyt.local:8000 \ -e TRONBYT_API_KEY= \ -- npx -y tronbyt-mcp

Claude Desktop: edit the config file — macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json — and add:

"mcpServers": { "tronbyt": { "command": "npx", "args": ["-y", "tronbyt-mcp"], "env": { "TRONBYT_BASE_URL": "http://tronbyt.local:8000", "TRONBYT_API_KEY": " " } } } }

Then restart Claude Desktop.

Any other MCP client: configure a stdio server with command npx, args ["-y", "tronbyt-mcp"], and the two environment variables above.

From source (instead of npx):

git clone https://github.com/jonfishr/tronbyt-mcp.git

cd tronbyt-mcp npm install && npm run build

Then use node /path/to/tronbyt-mcp/dist/index.js as the server command in your MCP client config (same environment variables).

Multiple displays? API keys are per-device, so add one entry per display (tronbyt-kitchen, tronbyt-office, …), each with its own key.

3. Check it works

Ask your assistant something like *"List my Tronbyt devices."* You should get back your display with its brightness, night mode, and app list. (In Claude Code, /mcp also shows the server and its tools.)

Configuration

Env var	Required	Default	Notes
`TRONBYT_BASE_URL`	yes	—	Your tronbyt/server, e.g. `http://tronbyt.local:8000`
`TRONBYT_API_KEY`	yes	—	Per-device API key from the Tronbyt web UI
`TRONBYT_TIMEOUT_MS`	no	`10000`	Per-request timeout

Usage

You don't call these directly — your assistant picks the right tool from your request — but this is what it has to work with:

Tool	What it does
`list_devices`	Devices visible to the key: brightness, night mode, pinned app, last seen
`update_device`	Set brightness, rotation interval, night/dim mode, pinned app
`reboot_device`	Reboot the display
`list_installations`	Apps installed on the device, with state and config
`update_installation`	Enable/disable, pin/unpin, or retime an installation
`delete_installation`	Remove an installation and its rendered images
`push_app`	Render a server-side app (with optional config) and show it
`push_image`	Push a base64 WebP (64×32, or 128×64 for wide displays) straight to the display
`push_text`	Render text to a display-sized WebP locally and push it

Push tools take background: false (default) interrupts the display and shows the push immediately; true saves it into the rotation without interrupting. When a key sees exactly one device (the normal case), device_id never needs to be specified.

`push_text`

Text is rendered with the Tom Thumb 3×5 pixel font, word-wrapped and centered. Printable ASCII only; \n forces a line break. Colors are hex (#ffcc00), default white on black.

Canvas size is detected from the device type (size: "auto"): standard displays get 64×32, wide/2x displays (tronbyt_s3_wide, raspberrypi_wide) get 128×64. On wide displays the font is doubled by default — same 16 chars × 5 lines, twice the pixels. Pass text_size: "small" for native-size glyphs (32 chars × 10 lines), or override the detection entirely with size: "64x32" / "128x64".

Removal

Claude Code: claude mcp remove tronbyt
Claude Desktop / other clients: delete the "tronbyt" entry from the config file and restart the client.
If you installed from source: delete the cloned directory. If you used npx, a cached copy may linger under ~/.npm/_npx; it's small and harmless, or clear it with npm cache clean --force.
On the server: anything you pushed shows up as an installation on the device — ask your assistant to delete it, or remove it in the Tronbyt web UI. Revoke the API key in the web UI if you're done with it. Nothing else is stored anywhere.

Development

npm install

npm test # vitest: unit + in-process MCP + stdio e2e (builds first) npm run build # tsc -> dist/ npm run gen:font # regenerate src/font.ts from scripts/tom-thumb.bdf

Smoke test against a real server (non-destructive — pushes to the rotation in background mode, then deletes the installation). Run from the repo root after a build:

TRONBYT_BASE_URL=http://tronbyt.local:8000 TRONBYT_API_KEY=<key> scripts/smoke.sh

Out of scope (v1)

update_firmware_settings — deliberately excluded; a bad value can leave a display unreachable
