Zero-knowledge persistent memory layer for Claude — MCP server

MemoraEU gives Claude a persistent, encrypted memory. All content is encrypted client-side with AES-256-GCM before reaching the server — the server never sees your plaintext. Semantic search is powered by Mistral embeddings generated locally on your machine, before encryption.

Features

• 🔒 Zero-knowledge — AES-256-GCM encryption, key never leaves your machine
• 🧠 Semantic search — embeddings generated locally before encryption (Qdrant on server)
• 🔄 Auto memory — remembers and recalls context automatically
• 🚫 Deduplication — detects near-duplicate memories before storing
• 🇪🇺 EU hosted — GDPR compliant infrastructure

Installation

pip install memoraeu-mcp

Or with uvx (no install required, recommended):

uvx memoraeu-mcp

Claude Desktop configuration

Add to your claudedesktopconfig.json, under mcpServers:

{
  "mcpServers": {
    "memoraeu": {
      "command": "uvx",
      "args": ["memoraeu-mcp"],
      "env": {
        "MEMORAEU_API_URL": "https://api.memoraeu.com",
        "MEMORAEU_API_KEY": "meu-sk-...",
        "MEMORAEU_SECRET": "your-memoraeu-password",
        "MEMORAEU_SALT": "your-kdf-salt",
        "MISTRAL_API_KEY": "your-mistral-key"
      }
    }
  }
}

Understanding the variables

These five variables serve three distinct purposes — they are not interchangeable:

Why does the MCP need its own Mistral key?

Zero-knowledge means the server never sees your plaintext. To enable semantic search, embeddings must be computed before the content is encrypted — on your machine. The MCP calls Mistral directly with the plaintext, gets the embedding vector, encrypts the content, then sends both to the server. The server stores the opaque blob and the vector, but cannot reconstruct the original text. Without MISTRALAPIKEY, semantic search will not work.

Without MISTRALAPIKEY: The MCP will still work — remember and recall will function, but semantic search will fall back to keyword-based search on the server side. Zero-knowledge encryption is unaffected.

Getting your keys

1. Sign up at app.memoraeu.com
2. Go to Settings → Encryption Keys → copy MEMORAEU_SALT
3. MEMORAEU_SECRET is your MemoraEU login password
4. Go to Settings → API Keys → create a key → copy MEMORAEUAPIKEY
5. Get a Mistral API key at console.mistral.ai

Remote MCP via SSE (no local install)

You can connect directly from claude.ai web, Cursor, Windsurf or any remote MCP client without installing anything locally:

SSE endpoint: https://api.memoraeu.com/mcp/sse
Auth: Authorization: Bearer meu-sk-...

Example config for Cursor / Windsurf:

{
  "mcpServers": {
    "memoraeu": {
      "type": "sse",
      "url": "https://api.memoraeu.com/mcp/sse",
      "headers": {
        "Authorization": "Bearer meu-sk-..."
      }
    }
  }
}
