Installation

To use with Claude Desktop, add the server config and environment variables:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "unomi-server": {
      "command": "npx",
      "args": ["@inoyu/mcp-unomi-server"],
      "env": {
        "UNOMI_BASE_URL": "http://your-unomi-server:8181",
        "UNOMI_VERSION": "3", // Use "2" for Unomi V2, "3" for Unomi V3 (default)
        "UNOMI_USERNAME": "your-username", // Required for V2, fallback for V3
        "UNOMI_PASSWORD": "your-password", // Required for V2, fallback for V3
        "UNOMI_PROFILE_ID": "your-profile-id",
        "UNOMI_KEY": "your-unomi-key", // Required for V2 only
        "UNOMI_EMAIL": "your-email@example.com",
        "UNOMI_SOURCE_ID": "claude-desktop",

Scope Management

The server automatically manages scopes for you:

1. Default Scope:

   • A default scope claude-desktop is used for all operations
   • Created automatically when needed
   • Used for profile updates and event tracking

2. Custom Scopes:

   • Can be created using the create_scope tool
   • Useful for separating different applications or contexts
   • Must exist before using in profile operations

3. Automatic Scope Creation:

   • The server checks if required scopes exist
   • Creates them automatically if missing
   • Uses meaningful defaults for scope metadata

Note: While scopes are created automatically when needed, you can still create them manually with custom names and descriptions using the create_scope tool.

Apache Unomi V2/V3 Compatibility

This MCP server supports both Apache Unomi V2 and V3 with automatic version detection and appropriate authentication methods.

Version Detection

The server automatically detects the Unomi version based on the UNOMI_VERSION environment variable:

• UNOMI_VERSION=2 - Uses V2 authentication (system administrator)
• UNOMI_VERSION=3 - Uses V3 authentication (tenant-based) - Default

V2 vs V3 Authentication

V2 (Legacy):

• Uses system administrator authentication (karaf/karaf by default)
• All operations use the same authentication method
• Requires UNOMI_USERNAME, UNOMI_PASSWORD, and UNOMI_KEY

V3 (Multi-tenant):

• Uses tenant-based authentication with API keys
• Different authentication for different endpoint types:
  • Public endpoints (/context.json): Uses X-Unomi-Api-Key header with public key
  • Private endpoints (profiles, scopes): Uses tenant authentication (tenantId:privateKey)
  • System operations: Falls back to system administrator authentication
• Requires UNOMI_TENANT_ID, UNOMI_PUBLIC_KEY, and UNOMI_PRIVATE_KEY

Migration from V2 to V3

1. Update environment variables:

   bashCopy

   # Remove V2-specific variables
   # UNOMI_KEY (no longer needed)
   
   # Add V3-specific variables
   UNOMI_VERSION=3
   UNOMI_TENANT_ID=your-tenant-id
   UNOMI_PUBLIC_KEY=your-public-key
   UNOMI_PRIVATE_KEY=your-private-key
   

2. Benefits of V3:

   • Complete data isolation between tenants
   • Enhanced security with tenant-specific API keys
   • Better scalability for multi-tenant deployments
   • Improved compliance with data privacy regulations

Configuration

Environment Variables

The server requires the following environment variables:

UNOMI_BASE_URL=http://your-unomi-server:8181
UNOMI_USERNAME=your-username
UNOMI_PASSWORD=your-password
UNOMI_PROFILE_ID=your-profile-id
UNOMI_SOURCE_ID=your-source-id
UNOMI_KEY=your-unomi-key
UNOMI_EMAIL=your-email

Profile Resolution

The server uses a two-step process to resolve the profile ID:

1. Email Lookup (if UNOMI_EMAIL is set):

   • Searches for a profile with matching email
   • If found, uses that profile's ID
   • Useful for maintaining consistent profile across sessions

2. Fallback Profile ID:

   • If email lookup fails or UNOMI_EMAIL is not set
   • Uses the UNOMI_PROFILE_ID from environment
   • Ensures a profile is always available

The response will indicate which method was used via the source field:

• "email_lookup": Profile found via email
• "environment": Using fallback profile ID

Unomi Server Configuration

1. Configure protected events in etc/org.apache.unomi.cluster.cfg:

   propertiesCopy

   # Required for protected events like property updates
   org.apache.unomi.cluster.authorization.key=your-unomi-key
   
   # Required to allow Claude Desktop to access Unomi
   # Replace your-claude-desktop-ip with your actual IP
   org.apache.unomi.ip.ranges=127.0.0.1,::1,your-claude-desktop-ip
   

2. Ensure your Unomi server has CORS properly configured in etc/org.apache.unomi.cors.cfg:

   propertiesCopy

   # Add your Claude Desktop origin if needed
   org.apache.unomi.cors.allowed.origins=http://localhost:*
   

3. Restart Unomi server to apply changes

Important: The Unomi key must match exactly between your server configuration and the UNOMI_KEY environment variable in Claude Desktop.

Configuration

Environment Variables

The server requires the following environment variables:

UNOMI_BASE_URL=http://your-unomi-server:8181
UNOMI_USERNAME=your-username
UNOMI_PASSWORD=your-password
UNOMI_PROFILE_ID=your-profile-id
UNOMI_SOURCE_ID=your-source-id
UNOMI_KEY=your-unomi-key
UNOMI_EMAIL=your-email

Profile Resolution

1. Email Lookup (if UNOMI_EMAIL is set):

   • Searches for a profile with matching email
   • If found, uses that profile's ID
   • Useful for maintaining consistent profile across sessions

2. Fallback Profile ID:

   • If email lookup fails or UNOMI_EMAIL is not set
   • Uses the UNOMI_PROFILE_ID from environment
   • Ensures a profile is always available

The response will indicate which method was used via the source field:

• "email_lookup": Profile found via email
• "environment": Using fallback profile ID

Unomi Server Configuration

1. Configure protected events in etc/org.apache.unomi.cluster.cfg:

   propertiesCopy

   # Required for protected events like property updates
   org.apache.unomi.cluster.authorization.key=your-unomi-key
   
   # Required to allow Claude Desktop to access Unomi
   # Replace your-claude-desktop-ip with your actual IP
   org.apache.unomi.ip.ranges=127.0.0.1,::1,your-claude-desktop-ip
   

2. Ensure your Unomi server has CORS properly configured in etc/org.apache.unomi.cors.cfg:

   propertiesCopy

   # Add your Claude Desktop origin if needed
   org.apache.unomi.cors.allowed.origins=http://localhost:*
   

3. Restart Unomi server to apply changes

Important: The Unomi key must match exactly between your server configuration and the UNOMI_KEY environment variable in Claude Desktop.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.

You can also tail the Claude Desktop logs to see MCP requests and responses:

# Follow logs in real-time
tail -n 20 -f ~/Library/Logs/Claude/mcp*.log

Session ID Format

When using get_my_profile, the session ID is automatically generated using the format:

[profileId]-YYYYMMDD

For example, if your profile ID is "user123" and today is March 15, 2024, the session ID would be:

user123-20240315

Troubleshooting

Common Issues

1. Protected Events Failing

   • Verify Unomi key matches exactly in both configurations
   • Check IP address is correctly whitelisted
   • Ensure scope exists before updating properties
   • Verify CORS configuration if needed

2. Profile Not Found

   • Check if UNOMI_EMAIL is correctly set
   • Verify email format is valid
   • Ensure profile exists in Unomi
   • Check if fallback UNOMI_PROFILE_ID is valid

3. Session Issues

   • Remember sessions are date-based
   • Only one session per profile per day
   • Check session ID format matches profileId-YYYYMMDD
   • Verify scope exists for session

4. Connection Problems

   • Verify Unomi server is running
   • Check network connectivity
   • Ensure UNOMI_BASE_URL is correct
   • Verify authentication credentials
