This server provides a Model Context Protocol (MCP) interface for AI agents to control, debug, and develop on Roku devices through the Roku Dev Studio application.
Device Management
Discover and scan for Roku devices (SSDP + subnet scan), list known devices with details (IP, serial, model, status)
Connect/focus a device tab in Dev Studio, test connectivity, and probe the bridge status
Remote Control
Send keypresses (Up, Down, Left, Right, Select, Home, Back, Play, etc.), input text, launch apps by ID, and deep link into apps with contentId/mediaType
Fetch app icons (returned as base64 data URLs)
Sideloading
Upload a channel package (.zip) via local file path or base64 content, and delete the sideloaded dev channel
BrightScript Debug Console (Telnet)
Connect to, read logs from (with cursor-based incremental fetching), and disconnect from the BrightScript debug console (port 8085)
ECP Queries & Commands
Run read-only ECP GET queries (device info, active app, media player state, installed apps, SceneGraph nodes, etc.)
Run ECP POST commands to arbitrary endpoints
App Connector / RALE
List channel-exported functions with parameter metadata, call channel functions, read SceneGraph node fields, run RALE built-in commands (node lookup, registry editor, update node, etc.)
Screenshots
Capture a screenshot of the current device screen, returned as an inline JPEG (base64)
Network Inspector
Check inspector status (enabled, capturing, MITM state), list and filter captured network events, retrieve full event details (headers + body), analyze traffic patterns (top hosts, content types, largest responses), and get HTTPS MITM CA info for decryption setup
Action Script Automation
List supported action types and their schemas, validate multi-step Action Scripts, and send them to the Dev Studio Builder for human review — supporting keypresses, text input, ECP queries/posts, launch, sideload, RALE commands, screenshots, performance capture, waits, conditionals, and variables
Allows AI agents to control and develop on Roku devices over local network or via remote server using ECP, including keypress, app launch, queries, sideloading, and more.
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).
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 | 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 |
| 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 |
| Runs |
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 |
AI-agent access | Nothing official | A bundled MCP server lets Cursor, Claude Desktop, or VS Code drive a real device |
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.

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 its URL via Add Remote Location in the device selector.
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.
