tap2cal-mcp

An MCP server for Tap2Cal.

Lets an AI assistant turn an event into a shareable add-to-calendar link. Anyone who opens the link saves the event to Google Calendar, Apple Calendar, Outlook or any other calendar with one tap, no app and no account needed.

You:    Make a calendar link for our summer party, July 5, 6 to 10 pm in
        Vienna, with RSVPs, and use the poster on my desktop as flyer.
Claude: [create_event, then set_flyer]
        Here is your link: https://tap2cal.com/summer-party

The assistant can do everything you can do in the app: create, change and delete events, choose the link, disable earlier links, add a flyer and read who accepted or declined.

Setup

Create a free account at tap2cal.com/app, open your account and create a key under "API and AI assistants". Events created with it appear under My events.

Claude Code

claude mcp add tap2cal -e TAP2CAL_API_KEY=t2c_YOUR_KEY -- npx -y tap2cal-mcp

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "tap2cal": {
      "command": "npx",
      "args": ["-y", "tap2cal-mcp"],
      "env": { "TAP2CAL_API_KEY": "t2c_YOUR_KEY" }
    }
  }
}

Cursor, Zed and other MCP clients

Same shape: command npx, args ["-y", "tap2cal-mcp"], and TAP2CAL_API_KEY in the environment.

Without installing anything

Clients that support remote servers can connect to the hosted server instead: https://mcp.tap2cal.com with the header Authorization: Bearer t2c_YOUR_KEY. This package adds one thing the hosted server can't do: set_flyer can read an image file from your computer.

The key is never a tool argument and never part of a tool result, so it does not end up in the conversation.
