What it does

Harmonia is the first MCP-native AI Music Agent — a one-stop companion for music creation, personalized listening, and agentic tasks. Users can voice-trigger song ideas, remix tracks via provider-agnostic tools, generate covers with BytePlus, enjoy a TikTok-style feed personalized by Qdrant, and get notes/emails or concert reminders through Composio integrations.

How we built it

We combined Morph LLM for reasoning/planning, Qdrant for personalization memory, Composio for Gmail/Calendar, and BytePlus for image generation. MCP glues these tools together into a flexible agentic workflow.

Challenges

Integrating multiple sponsor APIs, aligning MCP schemas, handling Gmail OAuth, and stitching a smooth demo under time pressure.

Accomplishments

Delivered an end-to-end agent demo (create → listen → chat → tasks). First hackathon version with real tool orchestration.

What we learned

How to design MCP schemas, chain tools into workflows, and balance UX with technical limits.

What’s next

Expand creator monetization, refine personalization loops, and integrate more MCP tools for a truly AI-native music ecosystem.
