# Ajouter dans votre config Claude Desktop :
# Server URL : https://api.memoraeu.com/mcp/sse
# Clé API sur : https://app.memoraeu.com
git clone https://github.com/pquattro/memoraeu-server
cd memoraeu-server
cp .env.example .env # remplir MEMORAEU_SECRET, MEMORAEU_SALT, MISTRAL_API_KEY
docker compose up -d
# API disponible sur http://localhost:8000

Le serveur MCP est conçu pour fonctionner sans intervention manuelle.

Au premier recall, le system prompt complet est injecté dans le contexte.

The MCP server is designed to work without manual intervention. The recall and remember tool descriptions instruct Claude to call them automatically — recall on the first message of each session, remember whenever information is worth retaining. On the first recall call, the full behavior system prompt is injected into Claude's context.
