Install

How do I install the CalculPro — outils de calcul du bâtiment MCP server?

CalculPro — outils de calcul du bâtiment is a hosted endpoint at https://calculpro.fr/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
calculer_chute_de_tension ~737

Calcule la chute de tension d'une canalisation électrique basse tension et la confronte aux limites de la NF C 15-100 § 525, par la méthode du guide UTE C 15-105. Deux usages selon que la section est connue : - vérification — donnez `section`, l'outil rend un verdict de conformité ; - dimensionnement — omettez `section`, l'outil retient la plus petite section normalisée qui tient la limite. Renvoie aussi la longueur maximale admissible, la tension à l'arrivée, les pertes Joule et la chute obtenue pour chaque section normalisée. Domaine de validité : une canalisation à section constante, en régime établi et charge équilibrée, conducteurs cuivre ou aluminium, réactance forfaitaire de 0,08 mΩ/m. L'outil ne vérifie NI le courant admissible du câble (échauffement, mode de pose, facteurs de correction), NI la protection contre les contacts indirects, NI le pouvoir de coupure des protections. La chute de tension n'est qu'un critère parmi d'autres : une section validée ici reste à vérifier en courant admissible avant d'être retenue.

NameTypeReqDescription
alimentationstring–Origine de l'installation. « reseau-bt » : branchement au réseau public basse tension, limites 3 % en éclairage et 5 % pour les autres usages — c'est le défaut, à la fois le cas le plus courant et le…
chute_amontnumber–Chute de tension déjà consommée en amont, en %, pour chaîner plusieurs tronçons (défaut 0).
cos_phinumber–Facteur de puissance du récepteur (défaut 0,85). Sans effet en courant continu.
courantnumber–Courant d'emploi IB, en ampères. Renseignez soit le courant, soit la puissance.
longueurnumberyesLongueur simple de la canalisation, en mètres. Donnez la distance aller seulement : le trajet retour est déjà pris en compte.
materiaustring–Métal du conducteur (défaut : cuivre).
moteur_demarrageboolean–Vérifier en plus la chute au démarrage d'un moteur asynchrone, sous cos φ 0,35 et une limite usuelle de 15 %.
puissancenumber–Puissance active transportée, en kW. Alternative au courant d'emploi.
rapport_id_innumber–Rapport courant de démarrage sur courant nominal du moteur (défaut 6 ; typiquement 5 à 8).
reseaustring–Type de réseau : « mono » phase + neutre, « tri » triphasé (défaut), « dc » courant continu.
sectionnumber–Section d'un conducteur, en mm². Omettez ce champ quand l'utilisateur cherche quelle section poser : l'outil bascule alors en dimensionnement.
tensionnumber–Tension nominale, en volts — entre phases en triphasé. Défauts : 230 V en monophasé, 400 V en triphasé, 48 V en continu.
usagestring–« eclairage » pour un circuit d'éclairage, limite plus sévère ; « autre » pour prises, force et moteurs (défaut).
