Quick start

Install OpenCode

Install OpenCode. For npm, Homebrew, Bun, Scoop, or Windows options, see the OpenCode install guide ↗.
```
curl -fsSL https://opencode.ai/install | bash
```

Install Cloudflare Skills

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

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

Launch OpenCode

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

For example:

Add a cron trigger to my Worker that processes a job queue every hour.

Cloudflare platform access

Expand any section to learn more.

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.

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:

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.

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.
