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 first: https://mymemory.dev/dashboard

One command

npx @mymemory.dev/mcp setup

This finds which of Claude Desktop, Claude Code, Cursor, Windsurf, VS Code and Codex CLI are installed, asks which ones to connect and for your API key, and adds everstash to each one's config — keeping whatever else is already there and backing up the file first. Restart the apps it touches when it's done.

Or set up manually

Add this to your MCP client's config (for example claude_desktop_config.json or .cursor/mcp.json), then restart the client:

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

Requires Node.js 18 or newer.

`save_memory`	Save text, a note or a URL as a memory, optionally into spaces
`search_memories`	Search your memories by meaning and keywords
