payotte-mcp

Serveur MCP (Model Context Protocol) de Payotte — l'annuaire immobilier canadien de professionnels vérifiés branché dans les IA, et les données immobilières de 10 pays (Canada, France, États-Unis, Royaume-Uni, Australie, Inde, Brésil, Mexique, Espagne, Belgique).

  • Hébergement : Cloudflare Workers, palier gratuit (100 000 requêtes/jour).
  • Zéro état, zéro maintenance : le worker lit en direct les feeds statiques de payotte.com (/api/experts.json, /api/regulators.json, /api/market.json), régénérés à chaque déploiement normal du site. Rien à mettre à jour ici quand les fiches changent.
  • Transport : Streamable HTTP sans état (POST JSON-RPC sur /mcp). Aucune dépendance.

Prérequis (une fois, ~10 min)

  1. Compte Cloudflare gratuit : https://dash.cloudflare.com/sign-up (obligatoire pour déployer).
  2. Compte GitHub gratuit (recommandé, pour lister le serveur dans les registres MCP → backlinks).

Déployer

cd ~/Desktop/payotte-mcp
npm install                 # une fois
npx wrangler login          # ouvre le navigateur, se connecter au compte Cloudflare
npm run deploy              # → https://payotte-mcp.<sous-domaine>.workers.dev

⚠️ Déployer d'abord le site payotte.com (build du 23 juillet ou plus récent) : les feeds /api/regulators.json et /api/market.json dont dépendent verifier_titre et stats_marche sont dans ce build. (/api/experts.json est déjà en ligne.)

L'URL MCP à donner aux clients (Claude, etc.) : https://payotte-mcp.<sous-domaine>.workers.dev/mcp

Tester en local (sans compte)

npm run dev                 # http://localhost:8787
curl -s localhost:8787/     # carte de visite du serveur
curl -s localhost:8787/mcp -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"trouver_expert","arguments":{"profession":"courtier immobilier","ville":"Montréal"}}}'

Brancher dans Claude

  • Claude Code : claude mcp add --transport http payotte https://payotte-mcp.<sous-domaine>.workers.dev/mcp
  • claude.ai (Connecteurs) : Paramètres → Connecteurs → Ajouter un connecteur personnalisé → coller l'URL /mcp.

Activer le relais de contact (contacter_expert)

Sans configuration, l'outil tourne en mode répétition (réponse simulée, aucun envoi). Pour l'activer :

  1. Côté site : le fichier privé /api/cx/{jeton}.json doit être déployé (jeton dans payotte-astro/src/lib/contactsToken.ts — NE JAMAIS lier cette URL). Secret Cloudflare correspondant : CONTACTS_TOKEN (déjà posé).
  2. Compte Resend gratuit (100 courriels/jour) : https://resend.com → ajouter le domaine payotte.com → poser les enregistrements DNS proposés (chez GoDaddy) → créer une clé API.
  3. printf 'LA_CLE' | npx wrangler secret put RESEND_API_KEY puis c'est actif — aucun redéploiement requis.

Adresse d'expédition : MAIL_FROM dans wrangler.toml (défaut Payotte <relais@payotte.com>).

Après le déploiement (l'antenne)

  1. Lister le serveur dans le registre MCP officiel (via GitHub) + annuaires communautaires → backlinks tech + découvrabilité par les agents.
  2. Angle RP : « premier annuaire immobilier canadien branché dans les IA ».
