To add intelligent querying, we introduced an MCP bridge (Node.js/Express backend) that connects the frontend to the subgraph via OpenAI. How it works: Users ask a natural-language question in the chat UI. The backend sends the message to the OpenAI API. The model returns a GraphQL query. The MCP client executes this query against the subgraph. The result is formatted and returned to the frontend. This enables on-the-fly queries about addresses, balances, trust links, and even custom transfer logic—without needing to understand GraphQL.
