What is the Remote MCP Server?

The Remote MCP Server allows AI assistants to securely access and use external tools through the Model Context Protocol. It runs on Cloudflare's edge network for low-latency worldwide access.

How does it work?

The server acts as a bridge between AI assistants (like Claude) and specialized tools. It handles authentication via OAuth and manages the communication protocol.

Key Use Cases

1. Extending AI capabilities with specialized tools 2. Secure remote access to computational resources 3. Developing and testing new MCP tools

Key Features

Cloudflare DeploymentHosted on Cloudflare Workers for global low-latency access
OAuth AuthenticationSecure login system to protect your tools and data
Tool IntegrationEasily connect various tools for AI assistants to use
MCP Inspector SupportBuilt-in support for testing and debugging with the MCP Inspector

Pros and Cons

Advantages
Global accessibility through Cloudflare's network
Secure authentication with OAuth
Easy integration with Claude and other AI assistants
Real-time tool invocation via SSE (Server-Sent Events)
Limitations
Requires Cloudflare account for deployment
Limited to tools compatible with MCP protocol
Initial setup may require technical knowledge

Getting Started

Local Development Setup
Clone the repository and install dependencies to run the server locally
Connect with MCP Inspector
Use the MCP Inspector tool to test your local server
Connect Claude Desktop
Configure Claude to use your local MCP server
Deploy to Cloudflare
Publish your server to Cloudflare Workers for remote access

Example Use Cases

Math CalculationsClaude uses the remote math tool to perform calculations
Data ProcessingProcess complex datasets through specialized remote tools

Frequently Asked Questions

What authentication credentials should I use for local testing?
How do I know if my tools are available to Claude?
What should I do if Claude doesn't recognize my tools?
Can I use this with other AI assistants besides Claude?
