Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security77
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability65
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1067 tokens (~533/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
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.

calculer_chute_de_tension Chute de tension d'un câble (NF C 15-100) ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| alimentation | string | – | 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_amont | number | – | Chute de tension déjà consommée en amont, en %, pour chaîner plusieurs tronçons (défaut 0). |
| cos_phi | number | – | Facteur de puissance du récepteur (défaut 0,85). Sans effet en courant continu. |
| courant | number | – | Courant d'emploi IB, en ampères. Renseignez soit le courant, soit la puissance. |
| longueur | number | yes | Longueur simple de la canalisation, en mètres. Donnez la distance aller seulement : le trajet retour est déjà pris en compte. |
| materiau | string | – | Métal du conducteur (défaut : cuivre). |
| moteur_demarrage | boolean | – | Vérifier en plus la chute au démarrage d'un moteur asynchrone, sous cos φ 0,35 et une limite usuelle de 15 %. |
| puissance | number | – | Puissance active transportée, en kW. Alternative au courant d'emploi. |
| rapport_id_in | number | – | Rapport courant de démarrage sur courant nominal du moteur (défaut 6 ; typiquement 5 à 8). |
| reseau | string | – | Type de réseau : « mono » phase + neutre, « tri » triphasé (défaut), « dc » courant continu. |
| section | number | – | Section d'un conducteur, en mm². Omettez ce champ quand l'utilisateur cherche quelle section poser : l'outil bascule alors en dimensionnement. |
| tension | number | – | Tension nominale, en volts — entre phases en triphasé. Défauts : 230 V en monophasé, 400 V en triphasé, 48 V en continu. |
| usage | string | – | « eclairage » pour un circuit d'éclairage, limite plus sévère ; « autre » pour prises, force et moteurs (défaut). |
