🚀 Quick Start
> 💡 Note: While these instructions focus on setting up the MCP server with Claude for Desktop, this server can be used with any MCP-compatible client. For more details on using different clients, see the MCP documentation.
Prerequisites
- uv package manager
- macOS with Calendar app configured
- An MCP client - Claude for desktop is recommended
Installation
Whilst this MCP server can be used with any MCP compatible client, the instructions below are for use with Claude for desktop.
1. Clone and Setup
# Clone the repository
git clone https://github.com/Omar-V2/mcp-ical.git
cd mcp-ical
# Install dependencies
uv sync
2. Configure Claude for Desktop
Create or edit ~/Library/Application\ Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"mcp-ical": {
"command": "uv",
"args": [
"--directory",
"/ABSOLUTE/PATH/TO/PARENT/FOLDER/mcp-ical",
"run",
"mcp-ical"
]
}
}
}
3. Launch Claude for Calendar Access
> ⚠️ Critical: Claude must be launched from the terminal to properly request calendar permissions. Launching directly from Finder will not trigger the permissions prompt.
Run the following command in your terminal.
/Applications/Claude.app/Contents/MacOS/Claude
> ⚠️ Warning: Alternatively, you can manually grant calendar access, but this involves modifying system files and should only be done if you understand the risks involved.
4. Start Using!
Try: "What's my schedule looking like for next week?"
> 🔑 Note: When you first use a calendar-related command, macOS will prompt for calendar access. This prompt will only appear if you launched Claude from the terminal as specified above.
🧪 Testing
> ⚠️ Warning: Tests will create temporary calendars and events. While cleanup is automatic, only run tests in development environments.
