What is the Date Time Tools MCP server?

If you already use Date Time Tools, the date time tools mcp server is the piece that lets your assistant work with it directly. A Model Context Protocol (MCP) server for date-time manipulation and timezone conversion, served over Streamable HTTP.

What the server does

This MCP server provides a set of tools for working with date-time strings, including timezone conversion, date mutation (arithmetic), and fetching the current date-time and timezone. It is designed to be used as a backend utility for applications or agents that need robust, standardized date-time operations.

  • Timezone Conversion —
  • Date Mutation —
  • Current Date-Time & Timezone —

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • convertTimezones — Convert a date-time string from one timezone to another
  • mutateDate — Add or subtract days, hours, minutes, months, or years from a date-time string
  • currentDateTimeAndTimezone — Get the current date, time, and timezone
  • Manual — Wrangler prints the public URL — for this project it's https://date-time-tools.iabhishek.workers.dev/mcp. The Workers Free plan covers this server

Credentials and setup notes

Configuration is passed through the environment: CLOUDFLARE_API_TOKEN, CLOUDFLARE_ACCOUNT_ID. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Installation goes through your MCP client rather than a global install: point it at wrangler on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

Among the file and storage access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Date Time Tools's toolset — convertTimezones, mutateDate, currentDateTimeAndTimezone and 1 more — is a fair guide to whether it matches your workflow. It is maintained by abhi12299; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Date Time Tools to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (convertTimezones, mutateDate, currentDateTimeAndTimezone, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Date Time Tools directly.
