MCP server that gives AI agents encrypted, persistent memory.

Setup

Add to your Claude Code or Cursor MCP config:

{

      "command": "npx",
      "args": ["context-chest-mcp"]
    }
  }
}

Tools

| Tool | Description | |------|-------------| | context-chest_remember | Store encrypted memory | | context-chest_recall | Search memories | | context-chest_read | Read decrypted content | | context-chest_forget | Delete a memory | | context-chest_browse | Browse memory tree | | context-chest_session-start | Start tracking a conversation | | context-chest_session-append | Add message to session | | context-chest_session-save | Extract memories and close session |

How it works

Content is encrypted client-side with AES-256-GCM before leaving your machine. The server stores only ciphertext. Keys are derived via HKDF from your credentials.
