Cloudflare Workers (via Bindings) MCP server for AI agents

The Cloudflare Workers Bindings MCP Server implements the Model Context Protocol (MCP), providing a way to manage your Cloudflare Workers Platform resources. With built-in Cloudflare OAuth, this server allows you to connect remotely and use various tools to interact with Cloudflare resources like KV namespaces, Workers, R2 buckets, D1 databases, and Hyperdrive configurations.

Available Tools

The MCP server provides tools across multiple Cloudflare resource categories:

Connecting to the MCP Server

Using MCP Clients with Native Support

If your MCP client natively supports remote servers:

Enter the server URL: https://bindings.mcp.cloudflare.com
The client will handle the connection (e.g., Cloudflare AI Playground)

Using Clients Without Native Support

If your client doesn't support remote MCP servers, set up with mcp-remote:

Install the mcp-remote package:
```
npm install mcp-remote
```

Create a configuration file with the following content:

{
  "mcpServers": {
    "cloudflare": {
      "command": "npx",
      "args": ["mcp-remote", "https://bindings.mcp.cloudflare.com/sse"]
    }
  }
}

Restart your MCP client
Complete the OAuth authentication flow in the browser window that opens
After authentication, the tools will be available for use

Example Prompts

Here are some prompts you can use to interact with the MCP server:

Account Management

List my Cloudflare accounts.
Set my active account to 'YOUR_ACCOUNT_ID'. (Replace YOUR_ACCOUNT_ID with an actual ID)

KV Namespace Operations

Show me my KV namespaces.
Create a new KV namespace called 'my-kv-store'.
Get the details for KV namespace 'YOUR_NAMESPACE_ID'. (Replace YOUR_NAMESPACE_ID)
Delete the KV namespace 'NAMESPACE_TO_DELETE_ID'. (Replace NAMESPACE_TO_DELETE_ID)

Workers Management

List my Cloudflare Workers.
Get the code for the 'my-worker-script' worker.

R2 Bucket Management

Show me my R2 buckets.
Create an R2 bucket named 'my-new-bucket'.
Get details for the R2 bucket 'my-data-bucket'.
Delete the R2 bucket 'old-bucket'.

D1 Database Operations

List my D1 databases.
Create a D1 database named 'analytics-db'.
Get details for D1 database 'YOUR_D1_DB_ID'. (Replace YOUR_D1_DB_ID)
Run the query 'SELECT * FROM customers LIMIT 10;' on D1 database 'YOUR_D1_DB_ID'. (Replace YOUR_D1_DB_ID)
Delete the D1 database 'TEMP_DB_ID'. (Replace TEMP_DB_ID)

Hyperdrive Configuration

List my Hyperdrive configurations.
Create a Hyperdrive config named 'prod-db-cache' for my database. (You might need to provide more origin details)
Get details for Hyperdrive config 'YOUR_HYPERDRIVE_ID'. (Replace YOUR_HYPERDRIVE_ID)
Update the cache settings for Hyperdrive config 'YOUR_HYPERDRIVE_ID'. (Replace YOUR_HYPERDRIVE_ID)
Delete the Hyperdrive config 'OLD_HYPERDRIVE_ID'. (Replace OLD_HYPERDRIVE_ID)

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
