Olympus

An AI-powered health platform that gives LLMs real-time access to your biometrics through a custom MCP server. Deployed on Vercel, syncs with Apple Watch.

Why This Exists

Most health apps show you dashboards. Olympus lets you talk to your health data. Ask "Why am I tired today?" and the AI pulls your sleep stages, HRV, and recovery scores to give you a real answer.

How It Works

Claude (or any LLM)
    ↓ MCP Protocol
MCP Server → exposes tools like get_sleep_data, log_food, get_hrv_trend
    ↓ REST
Next.js API routes → health data, USDA nutrition search, LLM client
    ↓ Drizzle ORM
PostgreSQL

The MCP server is the interesting part — it lets Claude autonomously query and log health data without copy-pasting. You just talk to it.

What I Built

MCP Server (/mcp-server)
Custom Model Context Protocol server exposing 27 tools: health summaries, sleep analysis, HRV trends, workout logs, food logging, USDA search, blood work, and longevity metrics.

Apple Watch Integration
Syncs real biometric data — sleep stages, HRV, workouts, recovery — from HealthKit.

RAG for Food Logging
"I had a chicken burrito" → USDA database search → structured macro/micronutrient JSON. No manual entry.

Pluggable LLM Backend
Local inference with Ollama/DeepSeek for privacy, or Groq API for speed. One env var to switch.

Stack

• Next.js 16 / React 19 / TypeScript / Tailwind
• PostgreSQL + Drizzle ORM
• MCP server with @modelcontextprotocol/sdk
• Apple HealthKit integration
• Ollama or Groq for LLM
• Deployed on Vercel

Running Locally

npm install

# Postgres
docker run --name olympus-db -e POSTGRES_DB=olympus -e POSTGRES_PASSWORD=password -p 5432:5432 -d postgres:16

cp .env.example .env.local
npm run db:push
npm run dev

Using the MCP Server with Claude

Build the MCP server:

cd mcp-server && npm install && npm run build

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "olympus": {
      "command": "node",
      "args": ["/path/to/olympus/mcp-server/dist/index.js"]
    }
  }
}

Restart Claude Desktop. You can now ask Claude things like "How did I sleep last night?" or "Log that I had a chicken burrito for lunch" and it will query/update your health data directly.
