Remote

You can run a remote MCP server that exposes your tools over an SSE endpoint, allowing clients to connect and invoke those tools without handling authentication. This setup is useful for quickly prototyping tool integrations and testing MCP workflows in cloud environments.

How to use

Connect to your remote MCP server from an MCP client or a compatible playground to start using your tools. For a Cloudflare-hosted deployment, you will access the server at the provided SSE URL and then load tools into your client of choice. If you are connecting from a local client, you can reference the server’s SSE endpoint directly in your client configuration.

How to install

Prerequisites: you should have Node.js and npm installed on your machine.

1. Create your MCP server project using the Cloudflare template.

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Additional steps you may use to connect and test

To connect a local MCP client or a desktop tool to your remote server, use the SSE URL exposed by your deployment. When configuring a client, point it to the server URL with the /sse path.

Additional notes

If you want to test tool access through a playground or desktop client, you can connect using the following example paths. The playground can load your remote MCP server by entering the URL that ends with /sse. Local testing can use a proxy configuration to reach the same /sse endpoint.

Advanced configuration and customization

To customize your server, edit the initialization to register your own tools. Within the source file, you’ll add tools by calling a method on your server instance such as this.server.tool(...) during initialization.
