Cloudflare MCP Server for IDE

Model Context Protocol (MCP) is a new, standardized protocol for managing context between large language models (LLMs) and external systems. In this repository, we provide an installer as well as an MCP Server for Cloudflare's API.

This lets you use Claude Desktop, and IDE like VSCode (Cline) and Windsurf or any MCP Client, to use natural language to accomplish things on your Cloudflare account, e.g.:

Please deploy me a new Worker with an example durable object.
Can you tell me about the data in my D1 database named '...'?
Can you copy all the entries from my KV namespace '...' into my R2 bucket '...'?

Demo

coming soon.

Setup

Add the server to your MCP client's configuration file (e.g., mcp_settings.json). Create the file if it doesn't exist. The location of this file varies depending on your MCP client. For Cline (VSCode extension), it's typically in the global storage path.

Example mcp_settings.json entry:

{
  "mcp_servers": [
     "cloudflare": {
       "command": "npx",
       "args": [
         "-y",
         "@deepbrainspace/cloudflare-mcp@1.1.1"
       ]
     }
  ]
}

Note: The @1.1.1 specifies the version. You can omit it to always use the latest version, or specify a different version if needed. The -y flag for npx automatically confirms any prompts, which is useful for non-interactive setups.

Restart your MCP client (e.g., Claude Desktop, VSCode with Cline). You should see a small 🔨 icon or similar indicator that shows the Cloudflare tools are available.

The first time you use a Cloudflare tool, the server will run its init process automatically if it hasn't been run before. This will prompt you for your Cloudflare Account ID and API Token. Alternatively, you can run npx @deepbrainspace/mcp-server-cloudflare init manually beforehand.
After initialization, the server will store your credentials securely. You should see a cloudflare section with your Cloudflare account ID in your MCP client's configuration or a dedicated configuration file created by the server.

For clients like Windsurf, ensure the MCP configuration file reflects the server addition similarly. Note that some clients might have limitations on the number of concurrent MCP tools.

Developing

In the current project folder, run:

pnpm install
pnpm build:watch

Then, in a second terminal:

node dist/index.js init

This will link Claude Desktop against your locally-installed version for you to test.

Usage outside of Claude

To run the server locally, run node dist/index run <account-id>.

If you're using an alternative MCP Client, or testing things locally, emit the tools/list command to get an up-to-date list of all available tools. Then you can call these directly using the tools/call command.

Publishing

To publish this package to the public npm registry under the @deepbrainspace scope, ensure you are logged into npm (pnpm login) and then run the following command from the cloudflare-mcp directory:

pnpm publish --access public

The --access public flag is crucial for scoped packages to ensure they are published publicly and not as private packages (which would require a paid npm plan).
