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.
Setup and use ActionCable for real-time features in Rails applications using WebSockets. Use when implementing real-time updates, live notifications, broadcasting changes, or when the user mentions WebSockets, ActionCable, channels, broadcasting, or Turbo Streams over cable.
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.
Subscribe to real-time stock market data via WebSocket (A-shares, HK stocks, ETFs). Use this skill when the user wants to monitor live stock prices, set up real-time alerts, or stream minute-level K-line data. Requires a valid real-time subscription token purchased from the management platform.
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.
Cloudflare Workers Runtime APIs including Fetch, Streams, Crypto, Cache, WebSockets, and Encoding. Use for HTTP requests, streaming, encryption, caching, real-time connections, or encountering API compatibility, response handling, stream processing errors.
API integration patterns including REST, GraphQL, WebSocket, and tRPC. Use when designing APIs, implementing data fetching, or building real-time features.
Real-time monitoring and analytics platform for Pump.fun tokens on Solana using WebSockets, HTML/CSS/JS
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"
Game networking protocols, WebSocket/UDP implementation, latency optimization for real-time multiplayer
Actix-web Rust web framework. Covers routing, extractors, middleware, state management, and WebSocket. Use for high-performance Rust APIs. USE WHEN: user mentions "actix-web", "actix", "rust web framework", "rust api", asks about "rust async web", "actix middleware", "actix extractors", "rust websocket", "high performance rust api" DO NOT USE FOR: Axum projects - use `axum` instead, Rocket projects - use `rocket` instead, Warp projects - use `warp` instead, non-Rust backends
