Overview

ENS MCP Server is a server designed for the Ethereum Name Service (ENS) that allows users to interact with the ENS system to resolve names, check availability, retrieve records, and more.

To use the ENS MCP Server, clone the repository, install the dependencies, configure Ethereum providers, and then run the server using either npx or a local script.

  • Resolve ENS names to Ethereum addresses. - Perform reverse lookups to get ENS names from Ethereum addresses. - Retrieve text records associated with ENS names. - Check the availability of ENS names for registration. - Get comprehensive information about ENS names, including ownership and history. - Support for subdomain queries and registration price checks.
  1. Resolving ENS names for dApps and wallets.
  2. Checking the availability of desired ENS names for new users.
  3. Retrieving metadata associated with ENS names for display in applications.
  4. Managing ENS name registrations and subdomains.

Use these steps to connect ENS MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "ens-mcp-server-justaname-id": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "ens-mcp-server-justaname-id": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "ens-mcp-server-justaname-id": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "ens-mcp-server-justaname-id": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "ens-mcp-server-justaname-id": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "ens-mcp-server-justaname-id": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-ens-mcp-server-justaname-id"
      ]
    }
  }
}
