Cursor · WhyVault

Available from the beta launch. Guide as of September 2026.

Add WhyVault to your MCP configuration – globally in ~/.cursor/mcp.json or for a single project in .cursor/mcp.json:

~/.cursor/mcp.json

{
  "mcpServers": {
    "whyvault": {
      "url": "<MCP address from the app>"
    }
  }
}

On first access Cursor opens the WhyVault sign-in window. After that WhyVault shows up in the list under Settings → MCP and you can use it in the agent chat.
