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

Run npx @cloudflare/mcp-server-cloudflare init

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

Features

KV Store Management

get_kvs: List all KV namespaces in your account
kv_get: Get a value from a KV namespace
kv_put: Store a value in a KV namespace
kv_list: List keys in a KV namespace
kv_delete: Delete a key from a KV namespace

R2 Storage Management

r2_list_buckets: List all R2 buckets in your account
r2_create_bucket: Create a new R2 bucket
r2_delete_bucket: Delete an R2 bucket
r2_list_objects: List objects in an R2 bucket
r2_get_object: Get an object from an R2 bucket
r2_put_object: Put an object into an R2 bucket
r2_delete_object: Delete an object from an R2 bucket

D1 Database Management

d1_list_databases: List all D1 databases in your account
d1_create_database: Create a new D1 database
d1_delete_database: Delete a D1 database
d1_query: Execute a SQL query against a D1 database

Workers Management

worker_list: List all Workers in your account
worker_get: Get a Worker's script content

Analytics

analytics_get: Retrieve analytics data for your domain
- Includes metrics like requests, bandwidth, threats, and page views
- Supports date range filtering

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.
