mnemosyne-mcp-server

Orpheus lost Eurydice because he looked back. Mnemosyne, titaness of memory, is the one who kept her name. This package family is the instrument of that preservation: adapters, SDKs, and runtimes that let AI agents store, recall, and forget without ever looking at the wrong thing at the wrong time.

Model Context Protocol server wrapping the Mnemosyne memory substrate. Exposes search, store, delete, and container-list tools to Claude Desktop, Cursor, and any MCP-compatible client. Single npx install, zero Python dependencies on the JS side.

Install

npx @mnemosyne-eurydice/mcp-server
# or globally:
npm install -g @mnemosyne-eurydice/mcp-server

Configure

export MNEMOSYNE_API_KEY="mn_..."

Use with Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "mnemosyne": {
      "command": "npx",
      "args": ["@mnemosyne-eurydice/mcp-server"],
      "env": { "MNEMOSYNE_API_KEY": "mn_..." }
    }
  }
}

How it works

This is a tiny Node.js wrapper. On first run, it creates a Python venv at ~/.mnemosyne/mcp-venv and installs the mnemosyne-mcp-server PyPI package. Subsequent runs reuse the venv.
