Cloudflare Skills

Persistent platform context that teaches the agent how Cloudflare works.

Skills are instructions the agent loads on demand. The cloudflare/skills bundle covers every layer of the platform — so the agent knows your conventions without you re-explaining them.

agents-sdkBuild AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat applications, voice agents, or browser automation. Covers Agent class, state management, callable RPC, Workflows, durable execution, queues, retries, observability, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

cloudflareComprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), feature flags (Flagship), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

cloudflare-email-serviceSend and receive transactional emails with Cloudflare Email Service (Email Sending + Email Routing). Use when building email sending (Workers binding or REST API), email routing, Agents SDK email handling, or integrating email into any app — Workers, Node.js, Python, Go, etc. Also use for email deliverability, SPF/DKIM/DMARC, wrangler email setup, MCP email tools, or when a coding agent needs to send emails. Even for simple requests like "add email to my Worker" — this skill has critical config details.

cloudflare-one"Guides Cloudflare One Zero Trust and SASE work across Access, Gateway, WARP, Tunnel, Cloudflare WAN, DLP, CASB, device posture, and identity. Use when designing, configuring, troubleshooting, or reviewing Cloudflare One deployments. Retrieval-first: use current Cloudflare docs/API schemas instead of embedded product docs."

cloudflare-one-migrationsPlans migrations from Zscaler ZIA/ZPA, Palo Alto, legacy VPN, SWG, or SASE stacks to Cloudflare One. Use for migration assessments, policy mapping, rollout plans, and parity/gap analysis.

durable-objectsCreate and review Cloudflare Durable Objects. Use when building stateful coordination (chat rooms, multiplayer games, booking systems), implementing RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code for best practices. Covers Workers integration, wrangler config, and testing with Vitest. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

sandbox-sdkBuild sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

turnstile-spinSet up Cloudflare Turnstile end-to-end in a project. Scan the codebase, create the widget via the Cloudflare API, embed it where user requests need bot verification (form submissions, SPA actions, API endpoints, download links, comment or vote submissions, etc.), wire canonical server-side siteverify in the customer's existing backend, validate, and persist the skill. Load this when a user asks to add Turnstile, set up CAPTCHA, protect a form or endpoint from bots, or fix a Turnstile integration. Mirrors developers.cloudflare.com/turnstile/spin.

web-perfAnalyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (LCP, INP, CLS) and supplementary metrics (FCP, TBT, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed. Biases towards retrieval from current documentation over pre-trained knowledge.

workers-best-practicesReviews and authors Cloudflare Workers code against production best practices. Load when writing new Workers, reviewing Worker code, configuring wrangler.jsonc, or checking for common Workers anti-patterns (streaming, floating promises, global state, secrets, bindings, observability). Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

wranglerCloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

MCP servers

Live access to the Cloudflare API, docs, and observability.

MCP servers provide typed tools to call into Cloudflare at runtime. There are two options: Code Mode — a single server that covers the entire Cloudflare API (2,500+ endpoints in ~1,000 tokens) — or a set of focused, domain-specific servers hosted in the cloudflare/mcp-server-cloudflare repo. The full catalog is also in the MCP servers for Cloudflare docs.

Wrangler CLI

Local dev, deploys, and Workers-specific commands.

Use Wrangler for local development, deploys, and product-specific commands like wrangler d1 migrations apply or wrangler tail. The bundled wrangler Skill teaches the agent when to reach for it.

What’s next

The unified cf CLI is in technical preview — a next-generation CLI that covers every Cloudflare product with consistent verbs and ergonomic output for agents. Try it with npx cf. Read the announcement →

Agent-friendly docs

Token-efficient references optimized for agents.

Append /index.md to any Cloudflare docs URL for a clean markdown version. Every top-level product section also has its own llms.txt — a page index sized for a single context window. A few useful ones:

developers.cloudflare.com/llms.txt — directory of every Cloudflare product.

developers.cloudflare.com/workers/llms.txt

developers.cloudflare.com/agents/llms.txt

developers.cloudflare.com/r2/llms.txt

developers.cloudflare.com/d1/llms.txt

For a full overview of how these docs are structured for agents, refer to the Docs for Agents guide.





Example prompts


Set up a Waiting Room to handle flash sale traffic spikes without dropping requests.Deploy a full-stack React app to Cloudflare Pages with a Workers API backend and D1 database.Set up rate limiting and WAF rules to block abuse on my public API.Deploy a globally distributed REST API on Workers with automatic scaling and zero cold starts.Check my Workers deployment logs for errors and suggest fixes.


Tips



The Cloudflare API MCP server uses Code Mode — Cascade writes JavaScript to reach any of 2,500+ endpoints in ~1,000 tokens.

Use @-mention to include your wrangler.jsonc in Cascade prompts — Cascade uses this to understand your current bindings when generating code.

Add the observability MCP server to let Cascade automatically check Workers logs and debug deployments without leaving the IDE.



FAQ










Does Windsurf support Cloudflare Skills?

Yes. Windsurf supports Agent Skills in Cascade. Install the Cloudflare Skills bundle from cloudflare/skills ↗ — see the Windsurf Cascade Skills documentation ↗ for where Cascade discovers and loads Skills.

Should I use Skills, the MCP server, Wrangler CLI, or all of them?

All three complement each other. Cloudflare Skills teach Cascade the patterns and conventions for Workers development. The Cloudflare API MCP server handles platform operations (DNS, WAF, Zero Trust, R2 buckets). Wrangler in Windsurf's integrated terminal covers local dev and deploys. Cascade coordinates between them naturally.

Can Cascade deploy to Cloudflare?

Yes. Cascade can run npx wrangler deploy in the integrated terminal, and with the MCP server configured it can also call the Cloudflare API directly for managed deploys and resource creation.




Troubleshooting










MCP server not connecting

Verify your mcp_config.json configuration. Restart Windsurf after making changes. Ensure the MCP server URL ends with /mcp.

Getting outdated information about Cloudflare products

Enable the Cloudflare docs MCP server so the agent can fetch current documentation at runtime. If you prefer not to use the MCP server, point the agent directly at developers.cloudflare.com/llms.txt for a directory of every product, or developers.cloudflare.com/<product>/llms.txt for a product-specific index.
