README
MemoraEU Server
Français
MemoraEU donne à votre IA une mémoire persistante et chiffrée — souveraine, zero-knowledge, hébergée en Europe. Compatible Claude, Cursor, Windsurf, ChatGPT via MCP. Auto-hébergement gratuit (AGPL v3) ou cloud géré EU.
Ce que ça fait
MemoraEU est un serveur de mémoire auto-hébergeable pour les assistants IA. Il implémente le Model Context Protocol (MCP) pour que n'importe quel client MCP (Claude, Cursor, Windsurf, ChatGPT…) puisse stocker et retrouver des souvenirs via recherche sémantique.
- Recherche sémantique propulsée par Qdrant + embeddings (Ollama ou Mistral)
- Multi-utilisateur / multi-org avec auth JWT
- Transports MCP : Legacy SSE (Cursor, curl) + HTTP Streamable (claude.ai 2025)
- Faits temporels avec périodes de validité
- Chiffrement zero-knowledge AES-256-GCM côté client (memoraeu-mcp)
- RGPD natif : endpoints export / suppression / historique intégrés
- Fusion intelligente : détection et merge de mémoires similaires via LLM (Mistral/Ollama)
Démarrage rapide

MemoraEU gives your AI a persistent, encrypted memory — sovereign, zero-knowledge, hosted in Europe. Works with Claude, Cursor, Windsurf, ChatGPT via MCP. Self-host for free (AGPL v3) or use the managed EU cloud.
What it does
MemoraEU is a self-hostable memory server for AI assistants. It implements the Model Context Protocol (MCP) so any MCP-compatible client (Claude, Cursor, Windsurf, ChatGPT…) can store and retrieve memories via semantic search.
- Semantic search powered by Qdrant + embeddings (Ollama or Mistral)
- Multi-user / multi-org with JWT auth
- MCP transports: Legacy SSE (Cursor, curl) + HTTP Streamable (claude.ai 2025)
- Temporal facts with validity periods
- Zero-knowledge encryption AES-256-GCM client-side (memoraeu-mcp)
- Native GDPR: built-in export / deletion / history endpoints
- Intelligent merge: similar memory detection and LLM-powered merge (Mistral/Ollama)
