time-mcp-server
Provides an MCP server with tools for current time retrieval by IANA timezone, converting times between timezones, reporting DST status, and returning time differences. Supports stdio (default) and SSE transports, and allows overriding detected local timezone.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
SSE transport implies an HTTP server, but the README does not document TLS requirements, authentication/authorization, or rate limiting. For stdio mode, it is typically local-process controlled. No secrets are mentioned, suggesting low secret-handling risk, but dependency and build-time security details are not provided.
⚡ Reliability
Best When
You want a local (or controlled) MCP time utility that an agent can call to normalize and convert times reliably using IANA timezone identifiers.
Avoid When
You need authenticated, rate-limited, multi-tenant network access over the public internet without additional deployment controls.
Use Cases
- • International meeting planning across timezones
- • Travel planning / checking local times at destinations
- • Remote work coordination across distributed teams
- • Event scheduling with correct local times
- • LLM workflows needing current time or timezone conversions
Not For
- • Security-sensitive time authority without validation/trust assumptions
- • Use as a source of truth for legal/financial deadlines without audit controls
- • High-concurrency public deployments without considering transport/auth hardening
Interface
Authentication
No authentication mechanism is described for the MCP server/tools. SSE mode exposes an HTTP endpoint; access control is not documented.
Pricing
No pricing model mentioned; appears to be a self-hosted open-source utility.
Agent Metadata
Known Gotchas
- ⚠ Current time results will vary by call time (non-deterministic output).
- ⚠ If users pass invalid/non-IANA timezone strings, behavior/error handling is not described in the README.
- ⚠ DST handling is provided but edge-case behavior around transitions is not documented; agents should be cautious when converting times exactly at DST boundaries.
