Cloudflare MCP Server

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, 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

Setup

1. Run npx @cloudflare/mcp-server-cloudflare init

   Note: The MCP server will automatically run npx wrangler login if you're not already authenticated with Cloudflare. You'll be prompted to complete the authentication process in your browser if needed.

3. Restart Claude Desktop, you should see a small 🔨 icon that shows the following tools available for use:

Paid Features

Some features in this MCP server require a paid Cloudflare Workers plan:

• Observability and Analytics: The analytics_get tool and related analytics features require a paid Workers plan to access these metrics
• Other premium Cloudflare features like advanced D1 database capabilities and higher usage limits also require appropriate paid plans

Ensure your Cloudflare account has the necessary subscription level for the features you intend to use.

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. If you're not already authenticated with Wrangler, the server will automatically prompt you to complete the authentication process in your browser.

Testing

The project uses Vitest as the testing framework with MSW (Mock Service Worker) for API mocking.

Running Tests

To run all tests:

pnpm test

To run tests with coverage:

pnpm test:coverage

To run a specific test file:

pnpm test -- tests/tools/queues.test.ts

To run tests in watch mode (useful during development):

pnpm test:watch

Test Structure

The test suite is organized as follows:

• tests/tools/: Contains tests for each Cloudflare API tool
• tests/mocks/: Contains mock data and request handlers
• tests/utils/: Contains test helper functions
• tests/setup.ts: Global test setup configuration

Each tool test file follows a consistent pattern of testing both successful operations and error handling scenarios.

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.
