n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

Upgrading from version 0.1.2

If you have version 0.1.2 or earlier installed, you need to manually remove it before installing the new version:

1. Uninstall the old package from n8n Community Nodes settings
2. Restart n8n to ensure the old package is completely removed
3. Install the new version from npm or GitHub

This is required due to a fix in package structure that prevents automatic updates from 0.1.2 to 0.1.3+.

Quick Start

1. Add SGR Agent node to your workflow
2. Connect AI Language Model (OpenAI, Anthropic, etc.)
3. Connect AI Tools (optional): search, MCP, LangChain tools
4. Connect Memory (optional): for conversation history

Example Workflow

Chat Trigger → SGR Agent → Output

Import SGR_Example.json to get started.

Features

• create_report_tool - generate detailed reports with citations
• clarification_tool - ask clarifying questions
