Cloudflare Worker Bindings MCP Server

This MCP server provides seamless access to Cloudflare Worker bindings directly within your development environment. It bridges the gap between your local workflow and Cloudflare's powerful edge computing platform, allowing you to interact with KV stores, Durable Objects, R2 buckets, and other Worker bindings without leaving your editor or IDE.

What It Does

The Cloudflare Worker Bindings MCP server acts as an intelligent interface layer between your development tools and Cloudflare's Worker runtime environment. It exposes your configured Worker bindings through the Model Context Protocol, enabling AI assistants and other MCP clients to read, write, and manage data across your Cloudflare infrastructure.

Features

KV Namespace Operations

• Read and write key-value pairs from your KV namespaces
• List keys with optional prefix filtering
• Delete entries and manage expiration times
• Retrieve metadata for stored values

R2 Storage Access

• Upload and download objects from R2 buckets
• List bucket contents with filtering capabilities
• Delete objects and manage bucket contents
• Access object metadata and properties

Durable Objects Integration

• Interact with Durable Object instances
• Send requests to Durable Object endpoints
• Manage state and coordinate between objects
• Access Durable Object storage APIs

D1 Database Queries

• Execute SQL queries against D1 databases
• Retrieve query results in structured format
• Perform database operations safely
• Access multiple D1 bindings simultaneously

Service Bindings

• Call other Workers through service bindings
• Pass requests between Worker services
• Access microservice architectures
• Coordinate distributed Worker applications

Use Cases

Development and Debugging: Quickly inspect and modify data in your KV stores or R2 buckets during development without switching to the Cloudflare dashboard.

Data Management: Perform bulk operations, data migrations, or cleanup tasks across your Worker bindings with the assistance of AI tools.

Testing and Validation: Verify that your Worker bindings contain the expected data and behave correctly before deploying to production.

Content Operations: Update configuration files, manage feature flags, or modify content stored in R2 buckets directly from your development environment.

Why Use This Server

This MCP server eliminates context switching and streamlines your workflow when working with Cloudflare Workers. Instead of juggling multiple browser tabs, CLI commands, or API calls, you can interact with all your Worker bindings through a unified interface. The integration with AI assistants means you can use natural language to perform complex operations across your Cloudflare infrastructure, making common tasks faster and reducing the likelihood of errors.
