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_USERNAME": "your-username", // by default Apache Unomi uses karaf  
        "UNOMI_PASSWORD": "your-password", // by default Apache Unomi uses karaf
        "UNOMI_PROFILE_ID": "your-profile-id",
        "UNOMI_KEY": "your-unomi-key", // by default Apache Unomi uses 670c26d1cc413346c3b2fd9ce65dab41
        "UNOMI_EMAIL": "your-email@example.com",
        "UNOMI_SOURCE_ID": "claude-desktop"
      }
    }
  }
}
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.

    • 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.

Overview

This MCP server enables Claude to maintain context about users through Apache Unomi's profile management system. Here's what you can achieve with it:

Key Capabilities

  1. User Recognition:
    • Identify users across conversations using email or profile ID
    • Maintain consistent user context between sessions
    • Automatically create and manage user profiles
  2. Context Management:
    • Store and retrieve user preferences
  3. Integration Features:
    • Seamless Claude Desktop integration
    • Automatic session management
    • Scope-based context isolation

What You Can Do

  • Have Claude remember user preferences across conversations
  • Store and retrieve user-specific information
  • Maintain consistent user context
  • Manage multiple users through email identification

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:
  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
    :
    # 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
    :
    # 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.

    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

  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

Logs to Check

  1. Claude Desktop Logs:
    # MacOS
~/Library/Logs/Claude/mcp*.log

# Windows
%APPDATA%\Claude\mcp*.log
  2. Unomi Server Logs:
    # Usually in
$UNOMI_HOME/logs/karaf.log

Quick Fixes

  1. Reset State:
    # Stop Claude Desktop
# Clear logs
rm ~/Library/Logs/Claude/mcp*.log
# Restart Claude Desktop
  2. Verify Configuration:
    # Check Unomi connection
curl -u username:password http://your-unomi-server:8181/cxs/cluster

# Test scope exists
curl -u username:password http://your-unomi-server:8181/cxs/scopes/claude-desktop

Claude Desktop Configuration options

  1. Create or edit your Claude Desktop configuration:
    • MacOS: 
      ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: 
      %APPDATA%/Claude/claude_desktop_config.json
  2. Add the server configuration using NPX:
    {
  "mcpServers": {
    "unomi-server": {
      "command": "npx",
      "args": ["@inoyu/mcp-unomi-server"],
      "env": {
        "UNOMI_BASE_URL": "http://your-unomi-server:8181",
        "UNOMI_USERNAME": "your-username",
        "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 ...
      }
    }
  }
}
