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 '...'?

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.
