Vreme Temporal MCP

Temporal intelligence for AI assistants

Give your AI assistant rich temporal awareness — timezone intelligence, cultural calendars, astronomical events, and time-sensitive context.

Works with Cursor, VS Code, Claude Desktop, Continue, Cline, and any MCP-compatible client.

What This Does

Instead of just knowing what time it is, your AI gets rich temporal context:

You: "What time is it in Tokyo?"

Claude: "Sunday, November 30, 2025 at 1:36 PM JST. Sunset in 2 hours 51 minutes.

🌅 Sunrise: 6:31 AM
🌇 Sunset: 4:28 PM  
🌙 Moon: Full Moon (70% illuminated)

📅 Hebrew: 10 Kislev 5786
📅 Islamic: 9 Jumada al-Thani 1447 AH
📅 Chinese: Year 2025, Month 10, Day 11 (Metal Snake)

⏰ Weekend - Not appropriate for work calls"

Features

• 🌍 200+ Timezones - All pytz timezones with DST handling
• 📅 9 Cultural Calendars - Hebrew, Islamic, Chinese, Hindu, Persian, Buddhist, Bahá'í, Ethiopian, Mayan
• 🕌 Islamic Prayer Times - All 5 daily prayers with qibla direction
• 🌅 Astronomical Events - Sunrise, sunset, moon phases, twilight times
• ✅ Activity Appropriateness - Smart recommendations for calls, meetings, work

How It Works

The MCP server connects your AI client to the Vreme Time API, which provides:

1. Natural language parsing - Understands your questions
2. Timezone calculations - Accurate time conversions
3. Cultural calendar conversions - 9 calendar systems
4. Astronomical computations - Sunrise, sunset, moon data
5. Activity analysis - Cultural and temporal appropriateness

All responses include full temporal context, not just clock time.
