How to Connect Claude Desktop & Cursor to Cloudflare D1 & Vectorize

Giving AI Assistants Direct Database Superpowers

Imagine asking **Claude Desktop** or **Cursor IDE**: > *"Query the last 10 error logs from my D1 database and find matching semantic vectors in Vectorize."*

With the **Model Context Protocol (MCP)**, your AI assistant can execute these queries safely without exposing database credentials or writing boilerplate scripts.

1. Setting Up the Cloudflare MCP Connector

1. Grab your Cloudflare API Token from your Cloudflare Dashboard. 2. Ensure your token has `D1:Edit` and `Vectorize:Edit` permissions. 3. Open your Cursor configuration (`~/.cursor/mcp.json`) or Claude Desktop config:

{
  "mcpServers": {
    "cloudflare-edge": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-cloudflare"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "YOUR_CLOUDFLARE_API_TOKEN",
        "CLOUDFLARE_ACCOUNT_ID": "YOUR_ACCOUNT_ID"
      }
    }
  }
}

2. Testing in Cursor IDE

Once configured, open Cursor Composer (`Ctrl+I` or `Cmd+I`) and prompt:

@cloudflare-edge show tables in my production D1 database

The AI assistant will invoke the MCP tool, query D1 at the edge, and summarize the schema in real time.
