Frequently asked questions

What is this MCP server?

It's a Cloudflare Workers template that implements a remote MCP server over SSE without requiring authentication.

How does it differ from a local MCP server?

It runs on Cloudflare's edge, accessible via a public URL, and uses SSE instead of stdio transport.

What runtime or dependencies are required?

Requires Node.js (for wrangler) and a Cloudflare account. The server runs on Cloudflare Workers.

Where does data or state live?

No persistent storage is included; state is ephemeral per worker instance unless you add bindings.

Is authentication supported?

No, this template deploys without any authentication layer.

CronWatch records every run of your scheduled jobs in your own database, and speaks up when one is missed, fails, gets stuck, runs slow or costs too much. CronWatch is free and open-source.
