Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

Coût et limites

Coût d'exécution

Quota d'API: Yahoo's public endpoints are best-effort; no official published limit — don't hammer
Tokens par appel: 200-2000 per response depending on depth
Monétaire: Free
Astuce: Cache statement queries — they update quarterly, not hourly. Avoid polling.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : None

Sortie de données : Queries to finance.yahoo.com (via yfinance library)

Yahoo can and does change endpoints; when the MCP breaks, update yfinance upstream.
Not for real-time trading — 15-20 min delay on most feeds.

Dépannage

Erreurs courantes et correctifs

Empty data for ticker

Ticker symbol wrong or delisted; try the exchange-suffixed form (e.g. TSLA vs 'TSLA.BA' for BA listing).

Vérifier : Search yahoo finance web for the ticker

429 Too Many Requests

yfinance hit Yahoo's informal limits. Back off 5 min; avoid tight loops.

ImportError on yfinance

Reinstall with uvx --upgrade — yfinance version lag is common.

Vérifier : uvx --from ... yahoo-finance-mcp --help
