Build Model Context Protocol (MCP) servers on Cloudflare Workers - the only platform with official remote MCP support. TypeScript-based with OAuth, Durable Objects, and WebSocket hibernation. Use when: deploying remote MCP servers, implementing OAuth (GitHub/Google), using dual transports (SSE/HTTP), or troubleshooting URL path mismatches, McpAgent exports, OAuth redirects, CORS issues.
Add Feishu (Lark) as a channel. Uses WebSocket long connection — no public URL or ngrok needed. Works alongside WhatsApp, Telegram, Slack, or as a standalone channel.
Testing WebSocket implementations for authentication bypass, cross-site hijacking, injection attacks, and insecure message handling during authorized security assessments.
Centrifugo real-time messaging server expert for WebSocket PUB/SUB, channel management, JWT authentication, event proxying, and horizontal scaling with Redis/NATS. Use when: centrifugo, centrifugal, real-time messaging, websocket pubsub, channel subscriptions, real-time notifications, live updates, presence, history recovery, server-sent events integration, real-time transport layer. Do not use for: general WebSocket programming without Centrifugo, Socket.IO, Pusher SDK, or other real-time frameworks.
Subscribe to BingX spot WebSocket market data streams including real-time trades, order book depth, K-lines, 24h ticker, latest price, best bid/ask, and incremental depth. Use when the user asks about real-time spot market data, live spot price feeds, streaming spot order books, or WebSocket subscriptions for spot trading.
Read market data for a known Kalshi prediction market on DFlow — orderbook, trades, top-of-book prices, candlesticks, forecast-percentile history, and Kalshi in-game live data — via one-shot REST snapshots, historical ranges, or live WebSocket streams. Use when the user asks "show me the orderbook for X", "get last hour of trades", "build a live price ticker", "stream orderbook depth", "pull 1-minute candles for the last day", "watch in-game scores for this sports market", or "alert me when the orderbook moves". Do NOT use to discover markets matching a criterion (use `dflow-kalshi-market-scanner`), to place orders (use `dflow-kalshi-trading`), or to read a user's own positions/P&L (use `dflow-kalshi-portfolio`).
Real-time monitoring and analytics platform for Pump.fun tokens on Solana using WebSockets, HTML/CSS/JS
Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for WebSocket and SSE handshakes, auth material, subscription state, realtime message schemas, reconnect behavior, and frame-driven runtime effects. Use when the user asks to inspect a WebSocket or SSE handshake, decode frames, trace subscriptions, follow reconnect logic, inspect auth material sent during realtime setup, or explain how live frames change rendered or persisted state. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.
Expert in real-time communication systems, including WebSockets, Socket.IO, SSE, and WebRTC.
Cloudflare Durable Objects stateful serverless playbook: DurableObjectState, Storage API (SQLite/KV), WebSocket hibernation, alarms, RPC, bindings, migrations, limits, pricing. Keywords: Durable Objects, DurableObjectState, DurableObjectStorage, SQLite, ctx.storage, WebSocket hibernation, acceptWebSocket, alarms, setAlarm, RPC, blockConcurrencyWhile.
Comprehensive guide for Cloudflare Durable Objects - globally unique, stateful objects for coordination, real-time communication, and persistent state management. Use when: building real-time applications, creating WebSocket servers with hibernation, implementing chat rooms or multiplayer games, coordinating between multiple clients, managing per-user or per-room state, implementing rate limiting or session management, scheduling tasks with alarms, building queues or workflows, or encountering "do class export", "new_sqlite_classes", "migrations required", "websocket hibernation", "alarm api error", or "global uniqueness" errors. Prevents 15+ documented issues: class not exported, missing migrations, wrong migration type, constructor overhead blocking hibernation, setTimeout breaking hibernation, in-memory state lost on hibernation, outgoing WebSocket not hibernating, global uniqueness confusion, partial deleteAll on KV backend, binding name mismatches, state size limits exceeded, non-atomic migrations, location hints misunderstood, alarm retry failures, and fetch calls blocking hibernation. Keywords: durable objects, cloudflare do, DurableObject class, do bindings, websocket hibernation, do state api, ctx.storage.sql, ctx.acceptWebSocket, webSocketMessage, alarm() handler, storage.setAlarm, idFromName, newUniqueId, getByName, DurableObjectStub, serializeAttachment, real-time cloudflare, multiplayer cloudflare, chat room workers, coordination cloudflare, stateful workers, new_sqlite_classes, do migrations, location hints, RPC methods, blockConcurrencyWhile, "do class export", "new_sqlite_classes", "migrations required", "websocket hibernation", "alarm api error", "global uniqueness", "binding not found"
Real-time communication patterns with WebSocket, Socket.io, Server-Sent Events, and scaling strategies
