Overview

To connect to a Cloudflare Worker MCP server, you will need:

1. Worker URL — the full https:// URL of your deployed Cloudflare Worker MCP server.

This guide will walk you through finding your worker URL and authorizing access.

​

Prerequisites

• A deployed Cloudflare Worker MCP server. See Cloudflare’s guide for how to build and deploy one.
• Your worker’s OAuth authorization server must allow the Nango callback URL as a redirect URI:
  • Production: https://api.nango.dev/oauth/callback
• Your worker’s OAuth authorization server must support the offline_access scope. Enable it in your OAuth provider settings to allow Nango to obtain a refresh token and keep the connection alive without re-authenticating.

1. Log in to the Cloudflare dashboard.
2. Go to Build > Compute > Workers & Pages in the left sidebar.

Step 2: Authorize in the Connect UI

1. Open the form where you need to connect your Cloudflare Worker MCP server.
2. Enter the full Worker URL in the respective field.

You are now connected to your Cloudflare Worker MCP server.
