Auth0 has collaborated with Cloudflare to help developers secure remote MCP servers powered by Cloudflare Workers. With the pace of MCP adoption rapidly increasing, Cloudflare has added features to its platform that handle the hard parts of building remote MCP servers, like workers-oauth-provider, an OAuth Provider that makes authorization easy. By securing your MCP server with Auth0, AI applications can now interact with an external API by connecting through the remote MCP server and make API calls on behalf of an authenticated user.
