Overview

What is Remote MCP Server on Cloudflare?

Remote MCP Server on Cloudflare is a reference implementation for running a Model Context Protocol (MCP) server on Cloudflare Workers, complete with OAuth login. It is intended for developers who want to expose MCP tools via a secure, serverless endpoint.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies, and run locally with npx nx dev remote-mcp-server. Deploy to Cloudflare using npm run deploy after creating a KV namespace. Connect clients like the MCP Inspector or Claude Desktop by pointing them to the server’s SSE endpoint (e.g., http://localhost:8787/sse locally or https://worker-name.account-name.workers.dev/sse after deployment).

Use cases of Remote MCP Server on Cloudflare

Deploying MCP tools that require authenticated remote access.
Prototyping and testing MCP servers locally before deployment.
Connecting Claude Desktop to a cloud-based MCP server.

Frequently asked questions

What transport does the server use?

The server communicates over SSE (Server-Sent Events). Clients connect to the `/sse` endpoint.

Can I run it locally without Cloudflare?

Yes. Use `npx nx dev remote-mcp-server` to run the server locally on `http://localhost:8787`.

How do I connect Claude Desktop to a deployed server?

Update the Claude Desktop configuration file (Settings > Developer > Edit Config) to use `npx mcp-remote` with the deployed Workers URL followed by `/sse`.

How do I authenticate when using the server?

The server implements an OAuth login flow. When connecting a client (e.g., MCP Inspector or Claude), a browser window opens for login. Locally, any email/password works; on deployment, the OAuth provider you configure is used.

What tools are included by default?

The README demonstrates a `math` tool for basic arithmetic, but the server can be extended with any MCP tools you define.
