MCP servers / Time

Time MCP server: setup for Claude Code, Claude Desktop and Cursor

The Time server gives your AI the current time and timezone conversion. Language models do not know what time it is, so questions about today's date, or a meeting spread across timezones, otherwise get guessed. It has two tools, get_current_time and convert_time, and both use standard IANA timezone names such as Europe/London.

It only reports and converts time. It cannot set reminders or create calendar events.

Runs with

uvx (uv, for Python)

Package

mcp-server-time on PyPI

Needs

Python tooling: it runs through uvx, which comes with uv.

Tools

2 (2 read-only)

Source

modelcontextprotocol/servers

Last checked

2026-09-20 (server reported version 1.30.0)

Config for Time

Generated by the same code as the free builder, so it matches what you get there. Pick your client, then copy.

Claude Code

Save as .mcp.json in your project root. Claude Code asks you to approve it the first time.

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

Or add it from a terminal instead (single quotes work in bash, zsh and PowerShell; more on this command):

claude mcp add time -- uvx mcp-server-time

Claude Desktop

Merge into claude_desktop_config.json (Settings → Developer → Edit Config), then fully quit and restart Claude Desktop.

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

Cursor

Save as .cursor/mcp.json in your project, or ~/.cursor/mcp.json for all projects.

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

What it can do

These are all 2 tools the server reported when we started it and asked on 2026-09-20. The labels come from the hints each tool declares about itself.

• get_current_time read-only
  Get current time in a specific timezone
• convert_time read-only
  Convert time between timezones

Watch out for

• Both tools are read-only, and it needs no key or account.
• By default it detects your system timezone. To set one yourself, add --local-timezone=Region/City to the arguments (see below).
• Give it IANA timezone names like America/New_York, which is what the README documents.

Variations

Set your own timezone

Replaces the automatic detection. We started the server with this flag to confirm it is accepted.

{
  "mcpServers": {
    "time": {
      "command": "uvx",
      "args": [
        "mcp-server-time",
        "--local-timezone=America/New_York"
      ]
    }
  }
}

The same in Claude Code, Claude Desktop and Cursor.

Try asking

• “What time is it in Tokyo right now?”
• “Convert 9:00 AM New York time to London and Sydney.”
• “It is 4 PM in Berlin. What time is that in San Francisco?”
