From the repository

Install the server with uv sync, then configure your MCP client (e.g., Claude for Desktop) by adding the server to claude_desktop_config.json with your OPENAI_API_KEY as an environment variable. Launch Claude from the terminal to trigger macOS calendar permissions. Once set up, invoke the single MCP tool send_to_calendar_agent with natural language requests like “What’s my schedule for next week?” or “Add a lunch meeting with Sarah tomorrow at noon.”

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.

MCP iCal Server

🗓️ Agent-Powered Calendar Management for macOS

</div>

> This project is based on Omar-V2/mcp-ical with a reimplemented user interaction layer using an agent-based approach.

🌟 Overview

Transform how you interact with your macOS calendar using a dedicated AI agent! This MCP iCal server leverages the OpenAI Agent SDK to provide a single, powerful entry point for all your calendar operations.

Unlike traditional MCP implementations that expose multiple tools, this server uses an agent-based approach:
- 🧠 Single Tool Interface: Just one MCP tool (send_to_calendar_agent) that delegates to a specialized calendar agent
- 🤖 Stateful Conversations: The agent maintains context between requests in the same session
- 🔄 Zero-Config Operation: Natural language processing handled automatically by the specialized agent

You: "What's my schedule for next week?" Claude: "Let me check that for you..." [Calendar agent processes request and returns clean schedule]

You: "Add a lunch meeting with Sarah tomorrow at noon" Claude: "Event created: Lunch with Sarah, tomorrow at 12:00 PM"
