Lu.ma MCP Server

A Model Context Protocol (MCP) server that provides AI agents with the ability to interact with the Lu.ma API for event and guest management.

Quick Start

1. Install the MCP server:

   npm install -g luma-mcp-server
   

2. Configure Claude Desktop:

   macOS:

   open ~/Library/Application\ Support/Claude/claude_desktop_config.json
   

   Windows:

   notepad %APPDATA%\Claude\claude_desktop_config.json
   

3. Add this configuration:

   {
     "mcpServers": {
       "luma": {
         "command": "npx",
         "args": ["luma-mcp-server"]
       }
     }
   }
   

4. Restart Claude Desktop

5. Start using it! Ask Claude:

   • "Please add my Lu.ma calendar with API key [your-key]"
   • "List my Lu.ma events"
   • "Export all guests to CSV"

Features

Configuration

Quick Setup with AI

The easiest way to configure the server is through the AI interface. Each Lu.ma API key is valid for a single calendar, but you can manage multiple calendars:

You: Please add my personal Lu.ma calendar with API key "luma_api_personal123"

AI: I'll configure your personal calendar with the provided API key.
[Configures calendar and validates it]
Calendar Added: personal
- Found 5 event(s) in this calendar
- Set as default calendar

You: Now add my work calendar with key "luma_api_work456"

AI: I'll add your work calendar.
[Configures second calendar]
Calendar Added: work
- Found 12 event(s) in this calendar

Manual Setup

Create a luma-config.json file in the project root:

{
  "calendars": [
    {
      "name": "personal",
      "apiKey": "your-personal-calendar-api-key",
      "description": "Personal events calendar"
    },
    {
      "name": "work",
      "apiKey": "your-work-calendar-api-key",
      "description": "Work events and meetings"
    }
  ],
  "defaultCalendar": "personal"
}

Getting Your API Key

1. Log in to your Lu.ma account
2. Ensure you have a Lu.ma Plus subscription
3. Navigate to your dashboard
4. Generate an API key in the API settings section

⚠️ Important: Keep your API key secure and never commit it to version control.

# Export with custom filename
export_guest_list(event_ids=["evt-abc123", "evt-def456"], filename="trust_square_guests.csv")

Note: The tool saves the CSV file directly to the filesystem and returns the full file path in the response.

Finding Your Exported Files

macOS:

• If installed from source: Check the exports/ folder in your luma-mcp-server directory
• If installed via npm: The file path will be shown in Claude's response

Windows:

• If installed from source: Check the exports\ folder in your luma-mcp-server directory
• If installed via npm: The file path will be shown in Claude's response

Tip: The easiest way to access your exported file is to copy the full path from Claude's response and open it directly in your file explorer or terminal.

Claude Desktop Configuration

macOS

1. Find your Claude Desktop configuration file:

   # The config file is located at:
   ~/Library/Application Support/Claude/claude_desktop_config.json
   

2. Open the configuration file:

   open ~/Library/Application\ Support/Claude/claude_desktop_config.json
   

   Or use your preferred text editor:

   nano "~/Library/Application Support/Claude/claude_desktop_config.json"
   

3. Add the Lu.ma MCP server configuration:

   If you installed via npm:

   {
     "mcpServers": {
       "luma": {
         "command": "npx",
         "args": ["luma-mcp-server"]
       }
     }
   }
   

   If you installed from source:

   {
     "mcpServers": {
       "luma": {
         "command": "node",
         "args": ["/Users/YOUR_USERNAME/path/to/luma-mcp-server/dist/index.js"]
       }
     }
   }
   

4. Save the file and restart Claude Desktop

Windows

1. Find your Claude Desktop configuration file:

   # The config file is located at:
   %APPDATA%\Claude\claude_desktop_config.json
   

2. Open the configuration file:

   Press Win + R, type the following, and press Enter:

   notepad %APPDATA%\Claude\claude_desktop_config.json
   

3. Add the Lu.ma MCP server configuration:

   If you installed via npm:

   {
     "mcpServers": {
       "luma": {
         "command": "npx.cmd",
         "args": ["luma-mcp-server"]
       }
     }
   }
   

   If you installed from source:

   {
     "mcpServers": {
       "luma": {
         "command": "node",
         "args": ["C:\\Users\\YOUR_USERNAME\\path\\to\\luma-mcp-server\\dist\\index.js"]
       }
     }
   }
   

   Note: On Windows, you must use double backslashes (\\) in the path.

4. Save the file and restart Claude Desktop

Verifying the Installation

1. Open Claude Desktop
2. Look for the MCP connection indicator (usually shown as a small icon or status)
3. Try asking Claude: "Can you list my Lu.ma calendars?"
4. If this is your first time, Claude will guide you through configuring your first calendar

Troubleshooting

MCP server not connecting:

• Ensure Node.js 18+ is installed: node --version
• Check that the path in your config file is correct
• On macOS, ensure you're using the correct path separators (/)
• On Windows, ensure you're using double backslashes (\\) in paths
• Check Claude Desktop logs for error messages

Permission errors on macOS:

• You may need to grant terminal/node permissions in System Preferences > Security & Privacy

Command not found errors:

• If using npm global install, ensure npm's global bin directory is in your PATH
• Try using the full path to node and the script instead

Multiple MCP Servers

If you have other MCP servers configured, your configuration might look like this:

{
  "mcpServers": {
    "luma": {
      "command": "npx",
      "args": ["luma-mcp-server"]
    },
    "other-server": {
      "command": "npx",
      "args": ["other-mcp-server"]
    }
  }
}

Common Issues and Solutions

"No calendars configured" Error

Solution: You need to configure at least one calendar first. Ask Claude: "Please add my Lu.ma calendar with API key [your-key]"

Cannot Find Exported CSV Files

Solution: Check the file path shown in Claude's response. You can also ask Claude: "Where are my exported CSV files saved?"

API Key Validation Failed

Possible causes:

• Invalid API key - double-check your key from Lu.ma dashboard
• No Lu.ma Plus subscription - API access requires Plus
• Wrong calendar - each API key is tied to a specific calendar

MCP Server Not Showing in Claude

Solutions:

1. Ensure Claude Desktop is fully closed and restart it
2. Check your config file syntax - must be valid JSON
3. Verify Node.js 18+ is installed: node --version
4. Check Claude Desktop logs for errors

API Rate Limits

Lu.ma enforces a rate limit of 300 requests per minute per calendar. The server automatically handles rate limit errors and provides appropriate error messages.

Error Handling

The server provides detailed error messages for common issues:

• 401 Unauthorized: Invalid API key or insufficient permissions
• 404 Not Found: Event or resource does not exist
• 429 Rate Limited: Too many requests (automatic retry recommended)
