MCP Server

Connect the Quick Sizer to Claude Chat, Claude Cowork, ChatGPT, and Claude Code.

Open Sizer

What is the MCP server?

Quick Sizer exposes a Model Context Protocol (MCP) server that lets Claude or ChatGPT calculate Cloudian HyperStore storage capacity on your behalf — directly inside a conversation. Once connected, you can ask things like "size a 20-node cluster with EC 9+3" and get an instant answer without opening the browser tool.

The server URL is https://configurator.storio.dev/api/mcp. Use this URL in all three connection methods below.

Claude Chat (claude.ai)

  1. 1Open claude.ai and go to Settings → Integrations.
  2. 2Click Add integration and choose MCP Server.
  3. 3
    Paste the server URL and click Connect:
    https://configurator.storio.dev/api/mcp
  4. 4A sign-in popup will appear — click through to authorize. Quick Sizer auto-approves all connections; no account is required.

Claude Cowork

  1. 1Open your Cowork workspace and go to Settings → Connectors.
  2. 2
    Add a new MCP connector with the URL:
    https://configurator.storio.dev/api/mcp
  3. 3Complete the OAuth sign-in flow. The connector is then available to all members of your workspace.

ChatGPT (desktop app)

  1. 1Open the ChatGPT desktop app and click your profile icon → Settings.
  2. 2Go to Connectors and click Add custom connector.
  3. 3
    Enter the server URL and click Save:
    https://configurator.storio.dev/api/mcp
  4. 4Complete the OAuth authorization prompt. The Quick Sizer tools will then be available in any new ChatGPT conversation.

Claude Code (CLI)

Add the server to your project's .claude/settings.json (or your global Claude Code settings for access in all projects):

{
  "mcpServers": {
    "quick-sizer": {
      "type": "http",
      "url": "https://configurator.storio.dev/api/mcp"
    }
  }
}

Restart Claude Code after saving. The four Quick Sizer tools will appear alongside your other MCP tools.
