Overview

The Marketplace Server is the core discovery layer of QuantX. It exposes tools to search the curated model registry, retrieve model details, manage subscriptions, and publish your own models. All models in the registry are reviewed and validated against institutional-grade standards before listing.

​
Connection

Add to your MCP client configuration: 
{
  "mcpServers": {
    "quantx-marketplace": {
      "url": "https://quantx-marketplace.quantspace.io/mcp"
    }
  }
}
Restart your client. The four marketplace tools will appear automatically. No token required for read-only tools (search_marketplace, get_model). Publishing and subscribing require a QuantSpace account token.
