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 60 s (Python) or via a hosted demo.
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!

Since mozilla announced the sunsetting of pocket, I started looking for alternatives, including building a light version for my personal use. But nothing came out of my research.
