About
A template for deploying an MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login, enabling remote MCP clients to connect over HTTP via SSE (Server-Sent Events).
Explore
- Deploy on Cloudflare Workers with OAuth authentication
- Local development with hot‑reload via Nx
- SSE transport for remote MCP client connections
- Compatible with MCP Inspector for testing
- Integrates with Claude Desktop via a local proxy (mcp-remote)
- Includes mock login for local development
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Remote MCP Server on CloudflareCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
cd ai
npm install
1. npx wrangler kv namespace create OAUTH_KV
2. Follow the guidance to add the kv namespace ID to wrangler.jsonc
3. npm run deploy
Just like you did above in "Develop locally", run the MCP inspector:
npx @modelcontextprotocol/inspector@latest
Then enter the workers.dev URL (ex: worker-name.account-name.workers.dev/sse) of your Worker in the inspector as the URL of the MCP server to connect to, and click "Connect".
You've now connected to your MCP server from a remote MCP client.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.
