How It Works

This MCP server wraps the Kabuzz REST API. When an agent calls a tool, the server translates it into the corresponding API call using your agent key for authentication. All spending controls, policy enforcement, and audit logging happen server-side exactly as they would with direct API calls.

All monetary values are in cents (e.g., 15000 = $150.00).

Agent Key Scopes

Your agent key determines what tools are available:

• buy — Search, offers (as buyer), purchases, messaging
• sell — Seller offers management, listing monitoring
• buy+sell — Everything

Development
