ENS MCP Server: Integrated Data Access for AI Applications

Overview: What is ENS MCP Server?

The Ethereum Name Service (ENS) MCP Server, implemented under Model Context Protocol (MCP), is an adapter designed to enable AI applications such as Claude Desktop, Continue, Cursor, and others to interact with the ENS system. This server allows these applications to resolve names, check name availability, retrieve records, and more, leveraging a standardized protocol for seamless data access.

🔧 Core Features & MCP Capabilities

The ENS MCP Server offers a comprehensive suite of functionalities through its various commands—resolve-name, reverse-lookup, get-text-record, check-availability, get-all-records, get-subdomains, get-name-history, and get-registration-price. Each command provides detailed interaction with the Ethereum Name Service, enabling AI applications to perform essential operations efficiently. These functionalities are built on top of MCP, ensuring compatibility across a wide range of services.

Detailed Command Flow

To understand how these commands interact within the MCP framework, we can visualize this flow using Mermaid diagrams:

This diagram illustrates how an AI application, through its MCP client, communicates with the ENS MCP Server via the Model Context Protocol. The server then interacts with the Ethereum Name Service API to execute operations and return results.

⚙️ MCP Architecture & Protocol Implementation

The ENS MCP Server adheres closely to the MCP architecture, providing a robust interface for integrated data access. This implementation ensures high compatibility with other MCP clients like Claude Desktop, Continue, Cursor, and more. The server handles error scenarios gracefully, offering user-friendly error messages while preserving technical details for debugging.

🚀 Getting Started with Installation

Prerequisites

Before you begin, ensure your environment meets the following requirements:

Node.js (v16 or higher): Install Node.js from nodejs.org.
npm or yarn: Use npm or yarn to manage dependencies.
Ethereum RPC Providers: Access to Ethereum providers is necessary; public or private nodes can be used.

Setup Steps

Clone the Repository

git clone https://github.com/JustaName-id/ens-mcp-server

Install Dependencies

Run the following command in the cloned directory:
```
npm i
```
Configure Ethereum Providers (Optional)

Create or update a .env file with your provider URLs:
```
PROVIDER_URL=https://your-provider-url.com,https://your-backup-provider.com
```
If no providers are specified, the default values will be used:

💡 Key Use Cases in AI Workflows

Real-World Application: Name Resolution and Ownership Verification

Imagine you are developing an AI application that needs to verify the owner of a specific ENS name to ensure secure data access. Using the resolve-name command, your AI can query for domain ownership with ease.

Technical Implementation Example

const resolveName = require('mcp-server-ens').resolveName;

async function checkOwner(ensName) {
  try {
    const address = await resolveName({ name: ensName });
    console.log(`The owner of ${ensName} is: ${address}`);
  } catch (error) {
    console.error('Error resolving ENS name:', error.message);
  }
}

Use Case: Name Availability and Pricing

Another common use case in AI applications is checking the availability of new names for registration. The check-availability command helps you efficiently check if a desired domain is available.

const checkAvailability = require('mcp-server-ens').checkAvailability;

async function availabilityCheck(ensName) {
  try {
    const status = await checkAvailability({ name: ensName });
    console.log(`The status of ${ensName} for registration is: ${status}`);
  } catch (error) {
    console.error('Error checking ENS name availability:', error.message);
  }
}

Sample MCP Configuration

To set up the server for your AI application, add the following configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "ens": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-ens"
      ],
      "env": {
        "PROVIDER_URL": "https://your-provider-url.com,https://your-backup-provider.com"
      }
    }
  }
}

📊 Performance & Compatibility Matrix

Ensure that the ENS MCP Server is optimized for performance and compatibility across various use cases. Its built-in error handling mechanisms and robustness make it a reliable choice for integration.

🛠️ Advanced Configuration & Security

For advanced users, you can customize the server settings via environment variables or configuration files to optimize its behavior. Key security considerations include securing API keys, setting appropriate timeouts, and implementing rate limiting.

Example of Advanced Configuration

Add this snippet to your .env file for customization:

API_KEY=your-unique-api-key
TIMEOUT=30s
RATE_LIMIT=100

❓ Frequently Asked Questions (FAQ)

Q: How does ENS MCP Server ensure secure data access?
