zAuctionHouse event system

zAuctionHouse provides a comprehensive event system with Pre-Events (cancellable) and Post-Events (informational).

Event Types

Pre-Events

Pre-Events fire before an action is executed. They are cancellable - you can prevent the action from happening.

AuctionPreRemoveListedItemEventBefore a listed item is removed
AuctionPreRemoveExpiredItemEventBefore an expired item is claimed

Post-Events

Post-Events fire after an action is completed. They are not cancellable - use them for logging, notifications, or integrations.

GroupeZ MCP

Documentation in your AI

MCP lets your AI search GroupeZ documentation and read current examples to help you configure your plugins.

Read-only · No documentation API key needed

1. Copy the server URL

Transport: HTTP (Streamable HTTP). Authentication: none. Your tool uses its own model and subscription limits.

  1. Open Plugins in ChatGPT on the web, then + → Add custom MCP server.
  2. Name it ‘GroupeZ Documentation’, paste the URL above and choose ‘No authentication’. Create and install the plugin.
  3. In a conversation, type @ and select the plugin before asking. If needed, enable search, get_page and list_pages in its settings.
Official setup guide

3. Ask a question

Use GroupeZ MCP to help me create a zMenu inventory. Search relevant pages, read the examples and cite your sources.
Other clients and troubleshooting

For clients using mcpServers, adapt this example to their format:

{
  "mcpServers": {
    "groupez-docs": {
      "url": ""
    }
  }
}

Available tools are search, get_page and list_pages. Refresh the connector’s tools after updates. If your AI cannot access them, check that the connector is enabled in the conversation and your account allows custom MCP servers. Opening the URL in a browser is not an MCP test.
