Ergo Explorer MCP is a comprehensive Model Context Protocol server that provides AI assistants with direct access to Ergo blockchain data through a standardized interface. It offers structured data delivery for blocks, transactions, token analytics, address intelligence, and ecosystem data, enabling natural language queries and automated workflows. The MCP supports both human-readable (Markdown) and machine-readable (JSON) responses, with a decorator for automatic format conversion, enabling consistent error handling and metadata across endpoints. Key capabilities include blockchain exploration (blocks, transactions, network statistics), address analysis (balances, transaction history, forensic analysis), token intelligence (token information, holder distributions, historical ownership, token collections), ecosystem integration (EIP information, oracle pool data, address book), advanced analytics (patterns, metrics, flows), entity identification and clustering (address relationships, co-spending, confidence scoring, visualizations), and Open WebUI integration for text and visualization tools. It also includes token estimation features and historical token holder tracking. The README mentions dual-format responses and integrated token estimation.
