Chaque outil déclare ces annotations MCP :

readOnlyHint — ne modifie jamais tes données — chaque appel ne fait que lire
idempotentHint — le même appel renvoie le même résultat, donc il peut être réessayé sans risque
openWorldHint — lit des données externes en direct, donc les résultats peuvent changer avec le temps

La localisation est donnée en coordonnées (lat/lng) — résolvez d'abord une adresse avec geocode_address.
Passez lang (en, de, fr, it, ru, es) pour localiser les champs texte ; la valeur par défaut est en.
Les outils de liste (search_properties, get_my_listings) se paginent avec page et size.
Les champs de réponse sont en snake_case.
Tous les outils couvrent actuellement la France — hors de France, ou si un fournisseur est indisponible, un outil renvoie un résultat vide ou null, jamais une erreur.

Outils

Une couverture détaillée sur tous les départements français, issue de huit jeux de données publics officiels — BDNB, IRIS, SSMSI, GeoRisques, Hub'Eau, Éducation IVAL, OpenStreetMap et DVF. D'autres marchés plus tard.
