Connect Claude, Cursor, VS Code and other MCP clients to your MyMemory (soon Everstash) account, so your AI assistant can save and recall your memories.

Setup

Create an API key in your dashboard: https://mymemory.dev/dashboard
Add this to your MCP client's config (for example claude_desktop_config.json or .cursor/mcp.json):

{
  "mcpServers": {
    "everstash": {
      "command": "npx",
      "args": ["-y", "@everstash/mcp"],
      "env": {
        "EVERSTASH_API_KEY": "your-api-key"
      }
    }
  }
}

Restart the client.

Requires Node.js 18 or newer.
