Inoyu Apache Unomi MCP Server

A Model Context Protocol server enabling Claude to maintain user context through Apache Unomi profile management.

⚠️ Early Implementation Notice

This is an early implementation intended for demonstration purposes:

• Not validated for production use
• Subject to changes
• Not (yet) officially supported
• For learning and experimentation only

Current Scope

This implementation provides:

• Profile lookup and creation using email
• Profile property management
• Basic session handling
• 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:

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:

   bash

   Copy

   # 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
