Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

{
  "mcpServers": {
    "cloudflare": {
      "command": "npx",
      "args": ["-y", "@cloudflare/mcp-server-cloudflare"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your-token"
      }
    }
  }
}

Now ask your AI agent:

"Deploy this Worker script to Cloudflare"
"List all KV namespaces"
"Query the users table in D1"
"Upload this file to R2 bucket"
