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 a full list of available Cloudflare MCP servers, refer to the repository on GitHub ↗.

   {
     "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 }
     }
   }

4. Launch OpenCode

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

   opencode

5. Try a prompt

   For example:

   Add a D1 database to my Worker and create a users table with CRUD endpoints.

Cloudflare Skills

Persistent platform context that teaches OpenCode how Cloudflare works.

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

• cloudflare Comprehensive platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and IaC (Terraform, Pulumi).
• agents-sdk Building stateful AI agents with state, scheduling, RPC, MCP servers, email, and streaming chat.
• durable-objects Stateful coordination (chat rooms, games, booking), RPC, SQLite, alarms, WebSockets.
• sandbox-sdk Secure code execution for AI code execution, code interpreters, CI/CD systems, and interactive dev environments.
• wrangler Deploying and managing Workers, KV, R2, D1, Vectorize, Queues, Workflows.
• web-perf Auditing Core Web Vitals (FCP, LCP, TBT, CLS), render-blocking resources, network chains.
• building-mcp-server-on-cloudflare Building remote MCP servers with tools, OAuth, and deployment.
• building-ai-agent-on-cloudflare Building AI agents with state, WebSockets, and tool integration.

MCP servers

Live access to the Cloudflare API, docs, and observability from inside OpenCode.

MCP servers give OpenCode typed tools to call into Cloudflare at runtime. The cloudflare/mcp-server-cloudflare repo hosts all of them; the full catalog is also in the MCP servers for Cloudflare docs. The API server alone exposes 2,500+ endpoints in ~1,000 tokens via Code Mode.

• cloudflare-api Entire Cloudflare API (2,500+ endpoints) in ~1,000 tokens via Code Mode.
• cloudflare-docs Up-to-date Cloudflare documentation and reference.
• cloudflare-bindings Build Workers applications with storage, AI, and compute primitives.
• cloudflare-builds Manage and get insights into Workers builds.
• cloudflare-observability Debug and analyze application logs and analytics.
• cloudflare-radar Global Internet traffic insights, trends, URL scans, and utilities.
• cloudflare-containers Spin up a sandbox development environment.
• cloudflare-browser Fetch web pages, convert them to markdown, and take screenshots.
• cloudflare-logpush Quick summaries for Logpush job health.
• cloudflare-ai-gateway Search AI Gateway logs and inspect prompts, responses, and token usage.
• cloudflare-autorag List and search documents on your AutoRAGs.
• cloudflare-auditlogs Query audit logs and generate reports for review.
• cloudflare-dns-analytics Optimize DNS performance and debug issues based on current setup.
• cloudflare-dex Digital Experience Monitoring — insights on critical applications.
• cloudflare-casb Cloudflare One CASB — identify SaaS security misconfigurations.
• cloudflare-graphql Query analytics data through Cloudflare's GraphQL API.

Wrangler CLI

Local dev, deploys, and Workers-specific commands.

OpenCode runs Wrangler directly in the terminal. The bundled wrangler Skill teaches it when to reach for CLI commands vs. the MCP API.

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

OpenCode requests markdown docs automatically.

OpenCode is one of the few agents that sends Accept: text/markdown by default when fetching Cloudflare docs, so it always gets the clean markdown version without any configuration. Useful URLs to reference explicitly:

• 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 AI tooling guide.

Example prompts

“Create a Cloudflare Workers application that serves as a backend API server.” “Add a D1 database to my Worker and create a users table with CRUD endpoints.” “Build an image upload service using R2 pre-signed URLs.” “Set up a KV namespace and use it for session storage in my Worker.” “Show me how to use Hyperdrive to connect my Worker to an existing Postgres database.” “Create an AI chat agent using the Cloudflare Agents SDK that maintains conversation history.” “Build a Workers AI chatbot with streaming responses.” “Build a WebSocket-based pub/sub app using Durable Objects with hibernation.” “Add a cron trigger to my Worker that runs every hour.” “Add rate limiting and bot protection to my API endpoints.” “Set up GitHub Actions to auto-deploy this Worker to Cloudflare.” “Create separate staging and production environments for my Worker.” “Generate Vitest tests for my Worker.” “Check my deployment logs for errors and suggest fixes.” “Deploy this project to Cloudflare Workers with a custom domain.”

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.
