Cicy Desktop

CiCy Desktop

CiCy Desktop is an Electron-based desktop automation worker with a small cluster control plane. It exposes ~100+ system tools — Chrome/CDP control, in-page JavaScript, screenshots, clipboard, file ops, shell/node/python exec, system info — over MCP and HTTP, plus a homepage UI for managing local and remote teams. The cicy-code sidecar daemon is acquired at runtime (npx cicy-code on mac/linux, Docker-in-WSL on Windows), not bundled.

Screenshots

The homepage — your teams (the local sidecar, private-cloud teams, and custom remote nodes), each a card you open as a tab:

CLI — cicy-desktop

cicy-desktop launches the Electron app — npm start and npx cicy-desktop run the same entrypoint. Self-update with cicy-desktop --update; --version and --help print info.

Run (end users, no clone)

First run launches the Electron app and drops a desktop shortcut (Windows .lnk / macOS .app / Linux .desktop, all with the CiCy icon); double-click it afterwards.

CN needs the electron mirror. A fresh machine has no cached electron binary, so electron's postinstall would otherwise hit GitHub releases and fail — point ELECTRON_MIRROR and the npm registry at npmmirror.

Windows — global install (not npx)

npx's libnpmexec lock false-positives as "Lock compromised" on Windows boxes with realtime antivirus (Defender touches node_modules mtimes mid-install). npm i -g has no such lock:

cmd /c "set ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/&& npm i -g cicy-desktop --registry=https://registry.npmmirror.com&& cicy-desktop"

Re-run the same line to update.

macOS / Linux — npx

ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/ npm_config_registry=https://registry.npmmirror.com npx -y cicy-desktop

Outside CN (or once electron is cached) a plain npx -y cicy-desktop is enough.

Develop

git clone git@github.com:cicy-ai/cicy-desktop.git
cd cicy-desktop
npm install
npm start

Config lives in ~/cicy-ai/global.json (API token, gateway key, node list). The worker reads its Authorization: Bearer from there.

Homepage UI (workers/render)

The desktop homepage — team cards, tabs, everything the user sees — is a Vite + React app in workers/render/. The Electron main process loads a prebuilt snapshot from src/backends/homepage-react/ (a file:// SPA: works offline, no mixed-content issues embedding the team webview). Source and snapshot are two different things — scripts/build-homepage.cjs (run on every build:* / publish) rebuilds the snapshot so it never lags behind workers/render/.

Build → ship the snapshot:

cd workers/render && npm run build
rsync -av --delete dist/ ../../src/backends/homepage-react/

Fast dev loop (React/CSS HMR, no Electron restart): run Vite and source-mode Electron with CICY_HOMEPAGE_URL=http://localhost:8173 set (via .env.dev). src/backends/homepage-window.js falls back to the bundled file:// SPA if that URL is unreachable, so the window never stays blank. Full platform/loop details (Mac fast loop, Windows packaged, the three reload classes) are in the worker's CLAUDE.md.

Calling tools

The worker dispatches its tools three ways:

• In-page (IPC): window.electronRPC(toolName, args) — the bridge injected

into trusted BrowserWindows.

• HTTP (REST): POST /rpc/:toolName with Authorization: Bearer —

served by the master, which forwards to the selected worker. 401 Unauthorized means the token is wrong or missing.

• From an agent: the agent-desktop / agent-electron / agent-chrome

skills drive a connected client over WebSocket (agent-desktop rpc , agent-desktop exec …, etc.).

Discover tools at runtime:

• list_tools meta-tool (electronRPC("list_tools") / agent-desktop rpc list_tools)
• GET /openapi.json (browsable at /docs)

The worker exposes automation for: browser window lifecycle and navigation, CDP page interaction, in-page JavaScript, screenshots / downloads / clipboard, system window control and system info, and worker/master cluster coordination.

Architecture

• worker/server entry — src/main.js
• desktop lifecycle CLI — bin/cicy-desktop
• tool implementations — src/tools/*
• master (routes POST /rpc/:toolName to workers) — src/master/master-routes.js
• homepage source — workers/render/ → built into src/backends/homepage-react/

The worker dispatches tools in-process via ipcMain.handle("rpc", …) (what window.electronRPC rides) and over HTTP; the live tool index is GET /openapi.json. The desktop CLI starts a local master + worker cluster and manages status/logs.
