Quick start

  1. Install Claude Code

    Install the Claude Code CLI. For Windows, Homebrew, WinGet, or npm, see the Claude Code setup guide ↗.

    curl -fsSL https://claude.ai/install.sh | bash

  2. Launch Claude Code in your project

    Start Claude Code from the root of your project, where wrangler.jsonc lives (if it already exists).

    claude

  3. Install the Cloudflare plugin

    In Claude Code, run these two slash commands. This installs Cloudflare Skills and registers the Cloudflare MCP servers.

    /plugin marketplace add cloudflare/skills
/plugin install cloudflare@cloudflare

  4. Try a prompt

    For example:

    Build a multi-tenant SaaS backend where each customer gets an isolated D1 database.

Cloudflare platform access

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, debug, or review Cloudflare Agents SDK applications using the agents package.
  • cloudflareDiscover and choose Cloudflare products for apps, APIs, AI agents, storage, networking, and security. Use for architecture and product selection, including when the user describes a need without naming a Cloudflare product; then find the relevant skill or documentation.
  • cloudflare-email-serviceImplement or troubleshoot Cloudflare Email Sending and Email Routing integrations and their delivery configuration.
  • cloudflare-oneDesign, configure, troubleshoot, or review Cloudflare One Zero Trust and SASE deployments. Use cloudflare-one-migrations for migration planning from other vendors.
  • cloudflare-one-migrationsAssess and plan migrations from existing VPN, SWG, or SASE platforms to Cloudflare One, including policy mapping, parity gaps, and rollout.
  • durable-objectsBuild, debug, or review Cloudflare Durable Objects code for persistent state and coordination.
  • nextjs-on-cloudflareBuild, migrate, and deploy Next.js apps on Cloudflare Workers with vinext. Use when starting a Next.js project on Cloudflare, moving an existing app to Workers, choosing between vinext and OpenNext, or setting up vinext for Workers. For setup, migration, or deployment, install vinext's upstream skills with `npx skills add cloudflare/vinext` if missing, then read and follow the applicable skill and docs.
  • sandbox-migrate-to-nextMigrate Cloudflare Sandbox apps from stable @cloudflare/sandbox to @cloudflare/sandbox@next (SDK 1.0 preview). Use sandbox-next for apps already on the preview.
  • sandbox-nextBuild or maintain Cloudflare Sandbox apps on @cloudflare/sandbox@next (SDK 1.0 preview). Use sandbox-migrate-to-next when porting a stable app.
  • sandbox-stableBuild or maintain Cloudflare Sandbox apps on the stable @cloudflare/sandbox package. Use sandbox-next for preview apps and sandbox-migrate-to-next for stable-to-preview migrations.
  • turnstile-spinSet up, repair, or migrate to Cloudflare Turnstile bot verification in an existing frontend and backend, including server-side Siteverify.
  • web-perfAudit, diagnose, or optimize website loading and interaction performance, Core Web Vitals, and Lighthouse performance scores.
  • workers-best-practicesCloudflare Workers best practices for production applications. Use when writing, reviewing, or configuring Workers.
  • wranglerRun or troubleshoot Wrangler CLI commands and configure Worker projects for local development, deployment, and Cloudflare resource management.
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.

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:

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

Example prompts

Set up a KV namespace for edge-cached session storage in my Worker.
Add bot protection and rate limiting to my login and checkout endpoints.
Configure Zero Trust access policies to protect my internal staging environment.
Deploy a globally distributed REST API on Workers with automatic scaling and zero cold starts.
Add a D1 database to my Worker and create a users table with full CRUD endpoints.

Tips

  • The Skills plugin includes a wrangler Skill — Claude knows when to reach for npx wrangler deploy, wrangler d1 migrations apply, and other CLI commands automatically.
  • Try the /cloudflare:build-agent slash command to scaffold a complete Agents SDK project, or /cloudflare:build-mcp for a remote MCP server.
  • The Cloudflare API MCP server uses Code Mode — Claude writes JavaScript against a TypeScript API to hit any of 2,500+ endpoints in ~1,000 tokens.
  • Claude Code works best from the root of your Workers project where wrangler.jsonc lives — this is what the agent uses to understand your bindings.
  • Use claude mcp list to verify Cloudflare servers are connected. For CI/CD, skip OAuth by passing a Cloudflare API token as a bearer token instead.

FAQ

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

All three — and the Skills plugin configures them together. Skills give Claude persistent Cloudflare knowledge (when to use Durable Objects vs KV, what a good Workers project layout looks like). The Cloudflare API MCP server handles platform operations (DNS, WAF, R2 buckets, Zero Trust). Wrangler runs local dev and Workers-specific commands. The wrangler Skill teaches Claude when to reach for which.

How do I give Claude Code access to my Cloudflare account?

The first time Claude calls a Cloudflare tool, you will be redirected to authorize via OAuth and choose what permissions to grant.

Can Claude Code deploy to existing Workers projects?

Yes. Run Claude Code from your existing project directory where wrangler.jsonc is located, and it will understand your project configuration and deploy accordingly.

What does Code Mode mean for MCP?

Code Mode is how the Cloudflare API MCP server fits all 2,500+ API endpoints into ~1,000 tokens. Instead of exposing every endpoint as a separate tool, it exposes two — search() and execute() — and Claude writes JavaScript to call them. Learn more about Code Mode ↗.

Troubleshooting

MCP server connection fails or times out

Run claude mcp list to verify the server is registered. Try removing and re-adding: claude mcp remove cloudflare then re-add it. Ensure you have npx and mcp-remote available.

Claude cannot authenticate with Cloudflare

The MCP server uses OAuth. When prompted, complete the authorization flow in your browser. For CI/CD, create a Cloudflare API token and pass it as a bearer token instead.

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.
