io.github.junct-bot/ens-mcp is a MCP server that provides twenty-three tools for ENS name resolution and reverse lookups.

About

io.github.junct-bot/ens-mcp brings Ethereum Name Service resolution into Model Context Protocol with twenty-three tools covering forward and reverse lookups. developers adding human-readable names to dApps, support bots, or internal admin tools can connect the remote MCP URL so Claude Code or Cursor validates `.eth` names and maps addresses without leaving the editor. Canonical placement is build → integrations alongside other protocol adapters; backend work overlaps when you implement resolution in API handlers. security reviews may use the server to double-check display names before go-live, but the server does not replace on-chain verification in production. Complexity is beginner-to-intermediate: concepts are familiar to Web3 devs, and setup is a single remote registration. It is an MCP data and lookup layer, not an ENS registrar or subdomain management suite.

What it does

Resolve ENS names and reverse lookups from your coding agent when building Web3 login, payment, or identity features.

Who is it for?

Best when you're adding ENS-powered labels, login hints, or support tooling and want lookup automation inside MCP-aware agents.

Skip if: Skip if you need registrar operations, DNS hybrid management, or authoritative on-chain proof without independent verification in production.

What you get

After registering the ENS MCP remote, your agent can resolve and reverse-resolve names while you implement identity and payment flows.

Twenty-three ENS lookup tools callable by your agent
Faster implementation of name-to-address and address-to-name features
Reduced manual explorer lookups during Web3 integration coding

Ens MCP Server

MCP server for Ens. Agent-ready API for Ens.

Hosted at ens.mcp.junct.dev/mcp. Free to use. No auth. No API key required.

Part of Junct — the agent-readiness layer for the crypto stack.

Quick Start

Add to your MCP client config (Claude Desktop, Cursor, Windsurf):

{
  "mcpServers": {
    "ens": {
      "url": "https://ens.mcp.junct.dev/mcp",
      "transport": "streamable-http"
    }
  }
}

About

This MCP server is deterministically generated from the Ens API specification. Every tool maps 1:1 to a real API endpoint — no hallucinated endpoints, no phantom tools.
