MCP Time Server

by One Shot Ship

A free, hosted MCP server providing accurate time and timezone tools for Claude Code — including remote /cowork sessions.

Quick Setup

claude mcp add --transport http time-server https://oss-mcp-time.onrender.com/mcp

With timezone hint (recommended):

claude mcp add --transport http \
  --header "X-Timezone: America/New_York" \
  time-server https://oss-mcp-time.onrender.com/mcp

Replace America/New_York with your IANA timezone.

Available Tools

get_current_time

Returns current time, date, UTC offset, and DST status for any IANA timezone.

Parameters:

Example response:

{
  "datetime": "2026-03-02T14:30:00",
  "timezone": "America/New_York",
  "utc_offset": "-05:00",
  "is_dst": false
}

convert_time

Converts a time from one timezone to another.

Parameters:

Example response:

{
  "source": "14:00",
  "target": "19:00",
  "source_timezone": "America/New_York",
  "target_timezone": "Europe/London",
  "utc_offset_source": "-05:00",
  "utc_offset_target": "+00:00"
}

Why?

Claude Code /cowork (remote) sessions run on Anthropic's infrastructure, not your machine. Local MCP servers like mcp-server-time aren't accessible. This hosted server solves that.

Self-Hosting
