Show HN: An MCP server that gives LLMs temporal awareness and time calculation

[lumbroso]

This is an open‑source Model Context Protocol (MCP) server that gives any LLM a sense of the passage of time.
Most MCP demos wire LLMs to external data stores. That’s useful, but MCP is also a chance to give models perception — extra senses beyond the prompt text.
Six functions (current_datetime, time_difference, timestamp_context, etc.) give Claude/GPT real temporal awareness: It can spot pauses, reason about rhythms, and even label a chat’s “three‑act structure”. Runs locally in
If time works, what else could we surface? - Location / movement (GPS, speed, “I’m on a train”) - Weather (rainy evening vs clear morning) - Device state (battery low, poor bandwidth) - Ambient modality (user is dictating on mobile vs typing at desk) - Calendar context (meeting starts in 5 min) - Biometric cues (heart‑rate spikes while coding)
Curious what other signals people think would unlock better collaboration.

Happy to discuss MCP patterns, tool discovery, or future “senses”. Feedback and PRs welcome!
