Description

This repository implements a Model Context Protocol (MCP) server wrapping the 3xpl JSON API, providing tools to resolve ENS names, inspect blocks, addresses, transactions, mempool data, fees, and perform aggregations. It supports 48 blockchains and offers many ready-made endpoints and aggregation helpers for LLM-driven workflows. The project also serves as an example of using the 3xpl JSON API and includes a sandbox mode when an API key is not provided.
