Time MCP: Documentation

Connection

uvx mcp-server-time (stdio). The optional --local-timezone flag sets a default timezone when it can't be auto-detected from the system. No authorization needed.

Tools

• get_current_time(timezone) — the current time in a given IANA timezone (e.g. Europe/Moscow or America/New_York).
• convert_time(source_timezone, time, target_timezone) — convert a specific time from one timezone to another.

Agent flow

"What time is it in Tokyo right now?", "convert 3pm Moscow time to New York time", "what local time will the call start if it's 6pm UTC?" — simple but frequent requests where a model without the tool can get the date or DST transition wrong.

Pricing

A free, open-source reference server (part of the modelcontextprotocol/servers monorepo); PulseMCP ranks it #18 by popularity among all MCP servers (~5.2M visits).
