Quick start

  1. Install OpenCode

    Install OpenCode. For npm, Homebrew, Bun, Scoop, or Windows options, see the OpenCode install guide ↗.

    curl -fsSL https://opencode.ai/install | bash

  2. Install Cloudflare Skills

    npx skills add https://github.com/cloudflare/skills

  3. Add Cloudflare MCP servers

    Add MCP servers to .opencode.jsonc. For domain-specific MCP servers, refer to mcp-server-cloudflare ↗. For the full Cloudflare API MCP server (Code Mode), refer to cloudflare/mcp ↗.

    {
  "mcp": {
    "cloudflare": { "type": "remote", "url": "https://mcp.cloudflare.com/mcp", "enabled": true },
    "cloudflare-docs": { "type": "remote", "url": "https://docs.mcp.cloudflare.com/mcp", "enabled": true },

    opencode

  5. Try a prompt

    For example:

    Add real-time collaboration to my app using Durable Objects with WebSocket hibernation.

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

Build a multi-tenant SaaS backend where each customer gets an isolated D1 database.
Create a RAG pipeline using Vectorize and Workers AI to answer questions over my documentation.
Build a serverless AI inference endpoint on Workers AI with streaming responses.
Configure Zero Trust access policies to protect my internal staging environment.
Set up rate limiting and WAF rules to block abuse on my public API.

Tips

  • The Cloudflare API MCP server uses Code Mode — OpenCode writes JavaScript to reach any of 2,500+ endpoints in ~1,000 tokens.
  • OpenCode supports 75+ LLMs — you can use Cloudflare Workers AI as the model provider for a fully Cloudflare-native workflow.
  • Use OpenCode's plan agent (Tab key) to break down complex Workers projects before coding — pair it with /cloudflare:build-agent or /cloudflare:build-mcp slash commands.

FAQ

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

All three. Skills provide persistent Cloudflare expertise so OpenCode knows when to reach for Durable Objects vs KV, how to structure a Workers project, and when to call CLI vs API. The Cloudflare API MCP server handles platform operations (DNS, WAF, Zero Trust, R2 buckets). Wrangler handles local dev, deploys, and Workers-specific commands. The bundled wrangler Skill teaches OpenCode which to use.

How do I connect OpenCode to Cloudflare?

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

Can I use Workers AI as the model provider in OpenCode?

Yes. OpenCode supports 75+ model providers, including Cloudflare Workers AI. Configure your model in .opencode.jsonc.

Is OpenCode open source?

Yes. OpenCode is fully open source and available at github.com/anomalyco/opencode.

Troubleshooting

MCP server connection fails

Verify the MCP configuration in .opencode.jsonc uses "type": "remote" with the correct URL. Run opencode mcp list to check connected servers.

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.
