This n8n workflow creates an intelligent chat-based system that provides real-time blockchain insights and analysis. Starting with a webhook trigger, it receives user messages, processes inquiries using an AI agent integrated with GPT-4.1-mini for natural language understanding, and connects to Nansen’s MCP (Multi-Chain Profile) tool through an HTTP stream of blockchain data. The workflow helps users understand complex blockchain activities by asking questions and receiving informed, contextual responses. Practical use cases include blockchain research, monitoring decentralized activities, or providing educational insights about on-chain events. The setup enables seamless conversational engagement with blockchain data, making complex analytics accessible and interactive.
