# Cloudflare MCP Server Model Context Protocol (MCP) is a [new, standardized protocol](https://modelcontextprotocol.io/introduction) 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](https://api.cloudflare.com). 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

Demonstrating the newly-released MCP server to explore Cloudflare properties, like Workers, KV, and D1.

## 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. ## Features ### KV Store Management -

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: ```bash pnpm test ``` To run tests with coverage: ```bash pnpm test:coverage ``` To run a specific test file: ```bash pnpm test -- tests/tools/queues.test.ts ``` To run tests in watch mode (useful during development): ```bash 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 `. 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. ### Workers ```javascript // List workers worker_list() // Get worker code worker_get({ name: "my-worker" }) // Update worker
