SAP Extension Creator

Overview

Create Super Agent Party extensions—self-contained packages that extend the platform with custom chat UI and tools. Two modes are supported:

• Static extension: Pure HTML/CSS/JS frontend, served directly by SAP from the extension folder
• Node.js extension: Full-stack with Express backend, auto-managed by SAP (npm install + node index.js <port>)

Both modes support MCP tool registration (the register_node_extension_mcp protocol message works for ANY extension via WebSocket, despite the "node" in its name).

Quick Decision Tree

User wants to create an extension?
├─ Only needs UI (chat, display, simple interactions)? → Static Extension
└─ Needs backend logic (API calls, DB, file processing)? → Node.js Extension
