Safety notes

  • Time MCP Server can provide current time values and convert times between timezones.
  • Incorrect timezone assumptions can cause missed meetings, bad deadlines, broken cron schedules, or confusing customer communications.
  • Require human review before using generated time conversions for travel, incident response, legal deadlines, medication timing, billing, payroll, or production scheduling.
  • Use the local timezone override when the runtime environment timezone differs from the user's expected working timezone.

Privacy notes

  • Timezone names and local timezone detection can reveal approximate location, travel patterns, work region, or operational context.
  • Time conversion prompts, meeting times, schedule details, target regions, and tool arguments may be visible to the MCP client and model provider.
  • Avoid using sensitive calendar, travel, incident, or personnel timing data unless it is approved for the current model session.

Prerequisites

  • Python 3.10 or newer available to the MCP client runtime.
  • uvx available for package execution.
  • IANA timezone names for any timezone you want Claude to query or convert.
  • Optional local timezone override if system timezone detection is not desired.

About this resource

Content

Time MCP Server is an official Model Context Protocol reference server for time queries and timezone conversion. It exposes tools for getting the current time in a specific timezone or the system timezone, and for converting a time between source and target IANA timezones.

The upstream README documents uvx, pip, and Docker configuration. The PyPI package exposes the mcp-server-time command for MCP clients.

Source Review

These sources were reviewed on 2026-06-05. Prefer the live repository and PyPI metadata for current package version, command name, Python requirement, dependencies, supported tools, timezone behavior, and setup guidance.

Features

  • Get the current time for an IANA timezone.
  • Use automatic system timezone detection when appropriate.
  • Convert a 24-hour time from one IANA timezone to another.
  • Override the local timezone when the runtime environment differs from the user context.
  • Run as an official reference MCP server through uvx, pip, or Docker.

Installation

For MCP clients that launch stdio servers:

{
  "mcpServers": {
    "time": {
      "command": "uvx",
      "args": ["mcp-server-time"]
    }
  }
}

Restart the MCP client after adding the server.

Use Cases

  • Ask Claude for the current time in another region.
  • Convert meeting times between teammates' timezones.
  • Check whether a remote team is inside normal working hours.
  • Translate launch, support, or maintenance windows into local time.
  • Avoid hard-coding timezone math in planning prompts.

Safety and Privacy

Timezone tools are simple, but wrong assumptions still matter. Confirm IANA timezone names, daylight-saving behavior, and local timezone overrides before using model-produced conversions for deadlines, travel, support coverage, incident response, finance, payroll, legal, medical, or production scheduling.

Timezone names, meeting times, schedule windows, travel plans, and target regions can reveal location and operational context. Keep sensitive timing data out of model sessions unless it is approved for that workflow.

Duplicate Check

No dedicated modelcontextprotocol/servers Time entry, mcp-server-time package entry, or matching source URL was found in content/mcp. The existing Sequential Thinking and Fetch entries are from the same official server monorepo but cover separate servers and packages.
