Gives Claude a persistent wall clock so it knows how much time passed between conversation turns. Exposes two MCP tools: temporal_tick advances the timeline and returns elapsed seconds plus day rollover detection, temporal_peek reads the gap without advancing state. Useful when you want the model to greet appropriately, detect resumed sessions, or reload daily context after midnight. Ships as both a Python stdio server for local use and a hosted HTTP endpoint at temporal-mcp.dev with bearer token or OAuth authentication. State persists per thread key in a local JSON file or remote D1 database. The hosted version is free tier Cloudflare Workers, self-hostable if you need scale or custom routing.
