workers-best-practices validates cloudflare workers code against 40+ production rules, flags 15+ anti-patterns, and retrieves live api definitions and wrangler schemas to avoid stale knowledge.

web-perf audits core web vitals and render-blocking resources via chrome devtools mcp. detects layout shifts, network chains, caching gaps, and accessibility issues with checklist-driven prioritization.

cloudflare-browser exposes CDP control over WebSocket to headless Chrome in Cloudflare Workers, enabling screenshots, navigation, scraping, and video capture. requires manual worker setup and environment configuration.

cloudflare-one-migrations maps policies and objects from zscaler, palo alto, legacy vpn/swg stacks into cloudflare one equivalents, with inventory buildup, dependency sequencing, and staged rollout guidance.

turnstile-spin orchestrates end-to-end cloudflare turnstile integration by reading codebases, provisioning widgets via api, deploying siteverify workers, and inserting frontend snippets with validation confirmation.

durable-objects covers cloudflare's persistent edge coordination layer via state management, rpc methods, and deterministic routing, with sqlite and kv storage. useful for real-time sync patterns but procedural depth is limited.

sandbox-sdk provides isolated code execution on cloudflare workers with npm package setup and docker dependency. documentation is sparse and lacks actionable procedural depth.

agents-sdk enables stateful ai agent construction on cloudflare workers via sqlite state management, rpc methods, task scheduling, and mcp server integration, with client-side react hooks for websocket communication.

guidance on deploying mcp servers to cloudflare workers with pointer to external docs. lacks procedural depth and concrete implementation examples.

building-ai-agent-on-cloudflare covers stateful ai agents on cloudflare workers using the agents sdk, with websocket communication, durable objects for persistence, and scheduled background tasks via cron or delay.

cloudflare-email-service describes sending transactional emails and email routing via cloudflare, but the documentation is incomplete - it declares itself a convenience guide that lags behind api reality and defers actual procedural instruction to external sources.
