Temporal Cortex MCP

v0.9.1 · March 2026 · Changelog · Website: temporal-cortex.com

Give any AI agent autonomous scheduling capabilities. Temporal Cortex is open scheduling infrastructure that lets any AI agent schedule reliably — whether the other person has an AI agent or not, uses Google Calendar or Outlook, or responds instantly or days later. 18 tools across 5 layers handle contact resolution, temporal reasoning, cross-provider availability, and atomic booking. Accessible via MCP, A2A, REST, and browser. Powered by Truth Engine. Install: npx @temporal-cortex/cortex-mcp.

Two ways to use Temporal Cortex

For individuals

Connect your calendars. Your AI agent handles the rest — checking availability, resolving time zones, and booking meetings without double-booking. Works with Claude Desktop, Cursor, OpenClaw, Manus, and any MCP-compatible AI client.

npx @temporal-cortex/cortex-mcp setup

The setup wizard walks you through provider authentication, timezone configuration, and MCP client setup interactively. You'll be scheduling in under a minute.

Or use the managed Platform — no Node.js required. Sign up at app.temporal-cortex.com, connect your calendars via OAuth, and add a single MCP config with your API key.

For developers

Add scheduling to your AI agent or product. 18 tools across 5 layers, 4 protocols (MCP, A2A, REST, Browser), atomic booking with Two-Phase Commit, and deterministic temporal computation powered by Truth Engine.

  • Local MCP server: npx @temporal-cortex/cortex-mcp — full tool suite, zero infrastructure
  • Platform REST API: app.temporal-cortex.com — managed hosting, API keys, usage dashboard, Open Scheduling network
  • Framework integrations: LangGraph, CrewAI, OpenAI Agents SDK
  • REST API reference: temporal-cortex.com/docs/rest-api

Why do AI agents fail at calendar tasks?

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
