Scheduling infrastructure for AI agents

ZenCal is a product of Amzu Information Technology Ltd. We build developer-first tools that let AI agents interact with the real world — starting with the calendar.

Most scheduling software is designed for humans clicking through web forms. We took a different approach: an API-first, agent-native platform where the setup, configuration, and day-to-day management are all driven programmatically by the agent — while the human invitee still gets a polished, intuitive booking experience.

ZenCal provides a complete scheduling stack as a service: availability management, booking pages, invite tokens, calendar sync, and lifecycle operations (cancel, reschedule) — all accessible via REST API and MCP tools.

• REST API — Bearer-authenticated endpoints for agents to create schedules, mint invites, and manage bookings.
• MCP Server — A stdio-transport MCP server so LLM-powered agents (Claude Desktop, Cursor, etc.) can drive scheduling with natural language.
• Public booking pages — Clean, responsive booking UI for the human on the other side of the meeting.
• Calendar integration — Google Calendar and Outlook sync so bookings land where users expect them.

ZenCal is built for developers and teams shipping AI agents that need to schedule meetings, demos, consultations, or any time-bound interaction. If your agent needs a calendar, we handle the infrastructure so you can focus on the agent's core logic.

• Agent-first, human-friendly — APIs for the agent, polished UI for the invitee.
• Security by default — Encrypted tokens, bearer auth with rotation, invite capability tokens, and no plaintext secret exposure.
• Transparency — Full audit logging for every admin action. You always know what happened and when.
• Simplicity— One bearer token, one MCP install, one setup URL. That's it.
