Scope management for context isolation

Other Unomi features (events, segments, session properties, etc.) are not currently implemented. Community feedback welcome on future development priorities.

Demo

Watch how the MCP server enables Claude to maintain context and manage user profiles:

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",
        "UNOMI_TENANT_ID": "your-tenant-id", // Required for V3
        "UNOMI_PUBLIC_KEY": "your-public-key", // Required for V3
        "UNOMI_PRIVATE_KEY": "your-private-key" // Required for V3
      }
    }
  }
}

The env section in the configuration allows you to set the required environment variables for the server. Replace the values with your actual Unomi server details.

Make sure to restart Claude Desktop after updating the configuration. You can then click on the tools icon on the lower right of the chat window to make sure it has found all the tools provided by this server.

Scope Management

The server automatically manages scopes for you:

Default Scope:
- A default scope claude-desktop is used for all operations
- Created automatically when needed
- Used for profile updates and event tracking
Custom Scopes:
- Can be created using the create_scope tool
- Useful for separating different applications or contexts
- Must exist before using in profile operations
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

Update environment variables:

# 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

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

Prerequisites

Running Apache Unomi server
Claude Desktop installation
Network access to Unomi server
Proper security configuration
Required environment variables

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:

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
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

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

# 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

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

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

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

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
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
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
Connection Problems
- Verify Unomi server is running
- Check network connectivity
- Ensure UNOMI_BASE_URL is correct
- Verify authentication credentials

Claude Desktop Configuration options

Create or edit your Claude Desktop configuration:
- MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%/Claude/claude_desktop_config.json

Add the server configuration using NPX:

{
  "mcpServers": {
    "unomi-server": {
      "command": "npx",
      "args": ["@inoyu/mcp-unomi-server"],
      "env": {

        "UNOMI_PASSWORD": "your-password",
        "UNOMI_PROFILE_ID": "your-profile-id",
        "UNOMI_KEY": "your-unomi-key",
        "UNOMI_EMAIL": "your-email@example.com",
        "UNOMI_SOURCE_ID": "claude-desktop"
      }
    }
  }
}

Note: Using NPX ensures you're always running the latest published version of the server.

Alternatively, if you want to use a specific version:

{
  "mcpServers": {
    "unomi-server": {
      "command": "npx",
      "args": ["@inoyu/mcp-unomi-server@0.1.0"],
      "env": {
        // ... environment variables ...
      }
    }
  }
}

For development or local installations:

{
  "mcpServers": {
    "unomi-server": {
      "command": "node",
      "args": ["/path/to/local/mcp-unomi-server/build/index.js"],
      "env": {
        // ... environment variables ...
      }
    }
