Temporal Cortex Calendar MCP
billylui/temporal-cortex-mcp
You'd reach for this when you need Claude to handle calendar operations without the uncertainty of natural language date parsing. It exposes 12 deterministic tools for temporal reasoning, letting Claude check availability windows, calculate scheduling constraints, and handle booking logic with precision. Think of it as a temporal calculator that gives Claude the ability to reason about "next Tuesday at 2pm" or "find three available slots in the next two weeks" with actual date math instead of fuzzy interpretation. The deterministic approach means you get consistent results for scheduling operations, which matters when you're building appointment systems or workflow automation that can't afford ambiguity about when things should happen.
