# Ethereum Name Service (ENS)

> Use this tool when you need to resolve decentralized domain names to Ethereum addresses or retrieve related information, such as text records or name history, to verify identity or interact with blockchain applications. It provides a comprehensive interface to the Ethereum Name Service, handling tasks like reverse lookups and name availability checks. With configurable network providers and robust error handling, it's ideal for building scalable and reliable blockchain-based systems that require decentralized naming and identity verification.

## Description

The ENS MCP Server enables Claude to interact with the Ethereum Name Service, providing tools to resolve ENS names to Ethereum addresses, perform reverse lookups, retrieve text records, check name availability, get registration prices, and explore name history. Built with TypeScript using the Model Context Protocol SDK, it connects to Ethereum networks through configurable providers and implements robust error handling for network issues and invalid inputs. This implementation by JustaName offers a complete interface to ENS functionality, making it valuable for blockchain applications that need to work with decentralized naming systems or verify Ethereum identity information.
