nvda-cpi-watch

MCP-Server + Repo-Agent fuer NVDA-Earnings + US-CPI Daten. Liefert historische Werte, Markt-Forecasts (Finnhub), Live-Nowcasts (Cleveland Fed), und einen aggregierten Trade-Brief fuer den naechsten CPI-Release.

Quickstart

cd ~/repos/nvda-cpi-watch
cp .env.example .env
# Edit .env: FINNHUB_API_KEY=... (free key from https://finnhub.io/register)

# Dependencies sind im venv installiert. Falls nicht:
python3 -m venv venv && venv/bin/pip install -r requirements.txt

# Agent spawnen (Repo-MCP wird automatisch geladen via .mcp.json):
tmux new-session -d -s nvda-cpi-watch "cd ~/repos/nvda-cpi-watch && claude --mcp-config .mcp.json"
tmux attach -t nvda-cpi-watch

Alternativ Standalone-Server testen:

venv/bin/python server.py < /dev/null   # startet stdio-loop, EOF beendet

Core YoY Derivation: Free APIs publizieren keinen direkten Core-CPI-YoY-Konsens (nur Core MoM). Wir berechnen es deterministisch: core_yoy_forecast = (latest_core_idx × (1 + core_mom_forecast/100)) / year_ago_core_idx - 1 mit latest_core_idx und year_ago_core_idx aus BLS. Source-Transparenz im _derivation-Feld des Briefs.

Cache-Files unter cache/*.json (gitignored). TTLs: BLS 6h, Finnhub Earnings 1h, Forecast 30min, Nowcast 3h.

Phase 1 = passiv

Aktuelle Phase: on-demand Daten-Server. Keine Alerts, keine Cron-Jobs, keine HA-Integration. Roadmap → vision.md.

Disclaimer

Daten-Server, keine Anlage- oder Trade-Beratung. Werte direkt aus BLS / Finnhub / Cleveland Fed; bei Drift Source pruefen.
