MCP Time Server on Cloudflare (Without Auth)

This example deploys a remote MCP time server that doesn't require authentication on Cloudflare Workers. It provides tools for getting the current time in different timezones and converting time between timezones.

Live Demo

You can try out a deployed version of this MCP Time Server at:

https://mcp-time-server.ajz.workers.dev/sse

Get started:

This will deploy your MCP time server to a URL like: mcp-time-server.<your-account>.workers.dev/sse

Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:

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

Available Tools

The MCP Time Server provides the following tools:

1. get_current_time

Parameters:
- timezone (optional): IANA timezone name (e.g., "America/New_York", "Europe/London"). Defaults to "UTC" if not provided.

Returns:
- The current date and time in the specified timezone in 24-hour format, along with the timezone information.

Example:

get_current_time(timezone: "America/New_York")

2. convert_time

Parameters:
- source_timezone: IANA timezone name for the source time (e.g., "America/New_York")
- time: Time in HH:MM format (24-hour)
- target_timezone: IANA timezone name for the target time (e.g., "Europe/London")

Returns:
- The converted time from the source timezone to the target timezone.

Example:

convert_time(source_timezone: "America/New_York", time: "14:30", target_timezone: "Europe/London")

Connect to Cloudflare AI Playground

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:

1. Go to https://playground.ai.cloudflare.com/
2. Enter your deployed MCP server URL (mcp-time-server.<your-account>.workers.dev/sse)
3. You can now use your MCP tools directly from the playground!

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from local MCP clients, by using the mcp-remote proxy.

To connect to your MCP server from Claude Desktop, follow Anthropic's Quickstart and within Claude Desktop go to Settings > Developer > Edit Config.

Update with this configuration:

{
  "mcpServers": {
    "time": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/sse"  // or mcp-time-server.your-account.workers.dev/sse
      ]
    }
  }
}

Restart Claude and you should see the time tools become available.
