# Temporal Cortex > Calendar scheduling infrastructure for AI agents ## What is Temporal Cortex? Temporal Cortex is an open-source MCP server that gives AI agents deterministic calendar capabilities. It prevents double-booking with Two-Phase Commit, expands recurrence rules deterministically via Truth Engine, and merges availability across Google Calendar, Outlook, and CalDAV into a unified view. ## Key Features - 11 MCP tools across 4 layers (temporal context, calendar ops, availability, booking) - Atomic booking with Two-Phase Commit (2PC) — lock, verify, write, release - Deterministic RRULE expansion via Truth Engine — handles DST, BYSETPOS, EXDATE - Multi-calendar availability merging — Google + Outlook + iCloud in one view - Temporal context and datetime resolution — timezone-aware, deterministic - Open source (MIT/Apache-2.0 core) with managed cloud option ## Installation npx @temporal-cortex/cortex-mcp ## Links - Homepage: https://temporal-cortex.com - GitHub: https://github.com/billylui/temporal-cortex-mcp - npm: https://www.npmjs.com/package/@temporal-cortex/cortex-mcp - crates.io: https://crates.io/crates/truth-engine - PyPI: https://pypi.org/project/temporal-cortex-toon/ - Agent Skill: https://github.com/billylui/temporal-cortex-skill
