MCP Clock: live public hosted tool for Claude, Codex, any MCP Client

Hi all,

I figured since it's been 2.5 years since ChatGPT launched and the labs haven't seen fit to let their default apps have a time tool, here's one:

Live MCP endpoint: https://mcpclock.firasd.workers.dev/mcp

Works in Claude.ai, Claude iOS, Claude Code, OpenAI Codex, and any MCP-compatible client.

It adds a handful of tools eg clock_get clock_day_info clock_convert clock_convert_unixtime clock_delta_utc

This way you can ask "what time will it be in Seattle when it's 5pm in Tokyo today" or "I'm halfway through my slides how much time is left to my 5pm deadline" etc
