Fitatu Nutrition MCP Server (FastAPI)

This server exposes daily nutrition data (meals and macros) through MCP HTTP Streamable transport. SQLite is used as a cache layer. Sync is additive: only new meal items are inserted; existing cached items are preserved.

Endpoints

• GET /health
• MCP Streamable HTTP endpoint: /mcp

MCP tools (HTTP Streamable)

• sync_day(day_date)
• get_day_summary(day_date)
• get_day_macros(day_date)
• get_day_meals(day_date)
• get_cache_stats(day_date)

sync_day also returns:

• cache_delta: newly added meals/items in this sync run
• cache_totals: total cached meals/items for that day

Parameter format: day_date = "YYYY-MM-DD"

Local run

Set credentials:

• FITATU_USERNAME
• FITATU_PASSWORD
• FITATU_API_SECRET — can be obtained by inspecting network requests in the Fitatu web app (e.g. via browser DevTools); look for the api-secret (or similar) header in authenticated API calls

Then run:

PowerShell:

pip install -r mcp_server/requirements.txt
$env:FITATU_USERNAME="your_email"
$env:FITATU_PASSWORD="your_password"
$env:FITATU_API_SECRET="your_api_secret"
python -m uvicorn mcp_server.server:app --host 0.0.0.0 --port 8000

bash/zsh:

pip install -r mcp_server/requirements.txt
export FITATU_USERNAME="your_email"
export FITATU_PASSWORD="your_password"
export FITATU_API_SECRET="your_api_secret"
python -m uvicorn mcp_server.server:app --host 0.0.0.0 --port 8000

Docker

Build image:

docker build -t fitatu-mcp-server ./mcp_server

Run container (username/password passed at runtime):

docker run --rm -p 8000:8000 \
  -e FITATU_USERNAME="your_email" \
  -e FITATU_PASSWORD="your_password" \
  -e FITATU_API_SECRET="your_api_secret" \
  -e FITATU_DB_FILE="/data/fitatu_nutrition.db" \
  -v "${PWD}/data:/data" \
  fitatu-mcp-server

Use MCP tool sync_day first, then read data with the remaining tools.

n8n MCP integration

Configure MCP client in n8n to use HTTP Streamable transport with URL:

• http://<host>:8000/mcp/

Use MCP tools listed above directly in n8n flows.
