Roku Dev Studio MCP sunucusu

Roku Developer Tools for macOS, Windows, and Linux — Remote Control, App Side-loading, ECP automation, RALE / App Connector, Network Inspector, Action Scripts, MCP server for AI agents (Cursor, Claude, VS Code), and a rds CLI. Supports both local network and internet-bridged devices.

A comprehensive cross-platform desktop application for controlling and developing on Roku devices over your local network or via remote server using the External Control Protocol (ECP).

Why Roku Dev Studio? (vs. official Roku tools)

Roku development is normally split across a pile of separate, single-purpose official tools — the Roku Remote Tool, the browser-based sideload installer, raw telnet, RALE, sca-cmd — that don't talk to each other. Roku Dev Studio doesn't replace Roku's own protocols (ECP, RALE, telnet, sca-cmd) — it wraps all of them in one GUI, one CLI (rds), and one MCP server:

Task	Without Roku Dev Studio	With Roku Dev Studio
Remote control	The official Roku Remote Tool, or raw ECP keypress calls via curl/Postman	One tab: full D-Pad, keyboard remote, and a floating mini-remote
Sideloading	The device's browser-based installer or a VS Code extension — one IP at a time	Sideload Relay — one push from your IDE installs, launches, and captures console on every targeted device
Debug console	telnet <ip> 8085 in a raw terminal or through an IDE — no search/filter/save either way	A structured console with search, filtering, and saved logs
BrightScript debugging	The socket debug protocol, usable mainly through a single IDE's extension	A standalone debugger: breakpoints, step execution, call stack, variables, watch
App inspection (RALE)	RALE alone only inspects SceneGraph nodes — no way to call into a channel or exchange data with it	App Connector — extends RALE with the ability to call your channel's own functions and pass data back and forth (GET/POST-style), unlocking automation that didn't exist before
Network traffic	A separately configured MITM proxy (Charles/mitmproxy/Fiddler) with manual device setup	Built-in local MITM proxy + optional hotspot packet capture
Static analysis	sca-cmd output cross-referenced by hand against Roku's cert docs	Runs sca-cmd for you, with cert-requirement links straight to Roku's docs
Remote locations / labs	Physical presence required — ECP only works on the local network	A bundled remote server bridges ECP over the internet
Repeatable testing	Hand-rolled scripts around ECP and RALE	Action Scripts — build a flow (keypresses, queries, conditionals, waits) from a GUI, or run it headless via rds
AI-agent access	Nothing official	A bundled MCP server lets Cursor, Claude Desktop, or VS Code drive a real device

Why have I built Roku Dev Studio?

This repository is an npm workspace monorepo. Run npm install and npm start from the repository root so workspaces link correctly. Installing runs a postinstall (npm run build:libs) that compiles the shared roku-dev-studio-platform and roku-dev-studio-api packages to their dist/ outputs, which the app and remote server import. Use npm run typecheck for a full TypeScript check across every workspace and npm test to run unit tests. CI runs these plus per-package build/syntax smoke checks on each push and pull request. Setup, scripts, and distributable builds are documented in INSTALLATION.md.

Repository layout

Location	What it is
apps/roku-dev-studio/	Electron desktop app (main process, renderer, packaging). Dev and distributable builds: INSTALLATION.md.
packages/roku-dev-studio-api/	Shared Node library + rds CLI: discovery, ECP, screenshots, sideload, RALE, action-script runner, headless validator — package README.
packages/roku-dev-studio-mcp/	MCP server that lets AI agents (Cursor, Claude Desktop, VS Code) drive a Roku through this app — package README.
packages/roku-dev-studio-network-inspector/	Network Inspector engine: hotspot packet capture (DNS/SNI/HTTP) + local MITM proxy, transport-agnostic so it runs in both the desktop app and the remote server — package README.
packages/roku-dev-studio-rce/	Roku Cloud Emulator (RCE) client — Core API (accounts / devices / snapshots) and Device API (ECP proxy, ports-bridge sockets) for cloud-hosted virtual Rokus, used by the app's RCE locations — package README.
packages/roku-dev-studio-remote-server/	HTTP/WebSocket relay to control Rokus over the internet — package README.
packages/roku-dev-studio-platform/	Shared host-platform helpers (OS identity, modifier keys, path-safe, node-only filesystem helpers) used by the app and other packages so platform logic lives in one place. Built to dist/ on npm install — package README.
roku-components/	BrightScript-side artifacts: TrackerTask.xml (drop into your channel for App Connector / RALE), the fiddle/ SceneGraph scaffold, and demo/ (the bundled Roku Dev Studio Showcase channel behind Try Demo App) — components README.

Glossary

Term	One-line meaning
ECP	External Control Protocol — Roku's HTTP API on port 8060 (KeyPress, Launch, Query, Deep-Link).
Telnet 8085 / 8080	The BrightScript debug console (8085) and dev system commands (8080) on a Developer-Mode Roku.
RALE	Roku Advanced Layout Editor — Roku's SceneGraph inspection protocol over a TCP socket (default port 49200), spoken by the TrackerTask component.
TrackerTask	The BrightScript component channel developers add to their app to make it reachable from RALE / App Connector — see roku-components/README.md.
App Connector	The Dev Studio tab that talks RALE: list / call your channel's GetExternalControlFunctions, plus built-ins (node lookup, registry editor, update node).
Network Inspector	The Dev Studio tab / engine that inspects a dev channel's HTTP(S) traffic through a local MITM proxy, with optional hotspot packet capture.
Sideload	Uploading and installing a .zip / .pkg dev channel onto a Developer-Mode Roku via its Dev Password.
Sideload Relay	RDS advertising itself as a Roku so one sideload from your IDE / browser fans out (install → launch → console) to many targeted devices.
Action Script	JSON-described automation that chains keypresses, queries, sideload, App Connector calls, screenshots, conditionals, waits, and variables. Built and run from the Action Scripts tab; also runnable headless via rds.
MCP server	Roku Dev Studio's Model Context Protocol server — lets Cursor / Claude Desktop / VS Code drive a real device through this app while it's open. Toggle clients in Settings → MCP Server.
Fiddle	The BrightScript scratch editor (Monaco + brighterscript lint) that wraps your snippet into a temporary channel and runs it on a selected device.
rds	The terminal CLI shipped by roku-dev-studio-api (rds discover, rds keypress, rds script run, rds rale repl, …).

Remote Server Setup

Roku Dev Studio can control devices over the internet using a remote server bridge, so you can manage devices in Remote Locations without being on the same network as the desktop app. Run the relay (npm run remote-server from this repo, or npm install -g roku-dev-studio-remote-server), then add it via Add Remote Location in the device selector. The modal has two tabs: RDS Relay (Relay Server address + port) and RCE (a Roku Cloud Emulator account name + Personal Access Token). RCE devices list as shutdown / pending / running and must be started first (Start, with optional snapshot / firmware / Max Run Time options) — ECP, sideload and console only respond while a device is running.

Full setup (running the server as a service, network/firewall configuration, the HTTP/WebSocket API, and Swagger docs) lives in the remote server package README.
