User Timezone FAQs

Question 1

What is the User Timezone tool?

Accepted Answer

The User Timezone tool is a remote Model Context Protocol (MCP) server implemented as a Cloudflare Worker. It offers a single function to detect and return a user's timezone based on their IP address when invoked from an MCP-compliant client.

Question 2

How does User Timezone determine a user's timezone?

Accepted Answer

It infers the user's timezone by performing an IP-based lookup. The tool extracts the user's apparent public IP address from standard HTTP headers, particularly Cloudflare headers, to achieve this detection.

Question 3

What are the privacy considerations for this tool?

Accepted Answer

Privacy is a key focus. The tool uses only the user's apparent public IP for timezone lookup. No personal data is retained or logged beyond temporary error diagnostics, and it operates as an authentication-free public endpoint for ease of use and experimentation.

Question 4

How do I use this tool with an MCP client like Claude Desktop or AI Playground?

Accepted Answer

To use it with an MCP client, connect the tool's `/sse` endpoint. The tool name to invoke is `get_timezone`, and it requires no parameters. It will return the user's timezone as a simple text message.

Question 5

Can I test the User Timezone functionality directly without an MCP client?

Accepted Answer

Yes, you can test its health endpoint directly using a `curl` command. It will respond with JSON containing the detected timezone and IP address. Note that IP-based detection might behave differently in local development environments.
