Mnemosyne + Claude Code

Give Claude Code persistent memory across sessions. It remembers your preferences, project context, and decisions.

Setup

1. Install Mnemosyne with MCP support:

pip install "mnemosyne-memory[mcp]"

2. Add to claude.json in your project root:

{
  "mcpServers": {
    "mnemosyne": {
      "command": "mnemosyne",
      "args": ["mcp"],
      "env": {}
    }
  }
}

3. Restart Claude Code. The tools register automatically.

Usage

In Claude Code:

/remember User prefers pnpm over npm
/recall project architecture decisions

Or ask naturally:

• "Remember that I use 2-space indentation"
• "What do you know about our auth system?"
• "Recall the discussion about the database schema"

CLI shortcuts

Claude Code slash commands:

• mnemosyne_remember — Store a memory
• mnemosyne_recall — Search memories
• mnemosyne_forget — Delete a memory

Project isolation

Use per-project memory banks to keep contexts separate:

{
  "mcpServers": {
    "mnemosyne": {
      "command": "mnemosyne",
      "args": ["mcp", "--bank", "my-project"],
      "env": {}
    }
  }
}
