Back to DirectoryCOMPARISON OVERVIEW
Time-aware assistants need authoritative timezone math — not model weights guessing DST rules. The official Time reference server provides "time and timezone conversion capabilities."
TOP PICK: TIME
Install (official README): uvx mcp-server-time
Python-based, two tools (per directory metadata) for time operations.
Strengths:
- Deterministic conversions — avoids LLM hallucination on UTC offsets
- Lightweight uvx launch — no Node required for this server alone
- Complements scheduling discussions in chat without calendar API integration
Trade-offs:
- Not a full calendar or cron MCP — no Google Calendar or Outlook in active reference set
- Read-only time data — does not create meetings
- Reference server scope — pair with productivity community servers for calendar writes
MEMORY FOR SCHEDULING CONTEXT
Remember standing meeting times, team TZ preferences:
npx -y @modelcontextprotocol/server-memory
FETCH FOR PUBLIC HOLIDAY / EVENT PAGES
Retrieve public holiday lists or conference schedules from URLs:
uvx mcp-server-fetch
COMPARISON DIMENSIONS
| Need | Server |
| Convert 3pm PT to Tokyo | Time |
| Remember "standup at 10am CET" | Memory |
| Read company holiday page | Fetch |
| Create calendar invite | Community calendar MCP (registry) |
SECURITY
Time MCP has minimal attack surface. Fetching arbitrary holiday URLs inherits standard SSRF considerations.
DECISION GUIDE
Always add Time when users mention timezones. Add Memory for recurring team norms. Use community calendar MCP when the assistant must write events to Outlook or Google Calendar.
