Adding a 2026 update for anyone landing here:

- Custom app → Genie Agents/Conversation API (start conversation, poll until complete)
- Claude, ChatGPT or another MCP client → Genie One MCP server via Unity Gateway: /ai-gateway/mcp-services/system.ai.genie_one_mcp
- Just need Genie inside a portal → iframe embed

Heads-up: the older /api/2.0/mcp/genie endpoint is deprecated and scheduled to sunset on Oct 31, 2026, so new integrations should use the Genie One MCP URL.
