ENS.Tools is a free web application for managing Ethereum Name Service (ENS) domains. Track expiry dates, renew in bulk, explore expiring names, search for available names, and create Web3 identity profiles.

How do I renew my ENS domain?

Connect your wallet on ENS.Tools, find your domain, click Extend, choose a duration, and confirm. Use Bulk Extend for multiple domains in a single transaction.

What happens when an ENS domain expires?

ENS domains enter a 90-day grace period, then a 21-day declining premium period. After 111 days total, the domain is released for anyone to register.

Can I find expiring ENS domains?

Yes, use the Expiry Explorer at ens.tools/find/expiry to browse domains expiring soon, in grace period, or in temporary premium.

ENS.Tools 2026: AI agents, ENSIP-25, and ENS v2 readiness

Building the most comprehensive ENS management platform — and preparing for what is next.

AI agent integration: the MCP server

ENS.Tools is now AI-native. We have built a full Model Context Protocol (MCP) server that lets AI agents — Claude, ChatGPT, custom bots — query ENS data directly through our platform. No API keys, no rate limits, completely open.

The MCP endpoint exposes nine tools:

lookup_domain — full domain details (owner, expiry, resolver, records)
check_expiry — batch expiry checking for multiple names
search_domains — pattern-based search
get_owner_domains — list all domains owned by an address
check_agent_verification — verify ENSIP-25 AI agent registrations
is_name_available — availability with grace-period awareness
get_name_price — real-time pricing from ENS contracts
get_subnames_for_name — list all subdomains for a parent
get_name_history — full event history

The endpoint is live at ens.tools/mcp and the discovery manifest sits at ens.tools/.well-known/mcp.json. We have also published a comprehensive llms.txt describing everything ENS.Tools can do.

ENSIP-25: AI agent identity verification

As AI agents become first-class participants on Ethereum, verifying their identity matters. We now fully support ENSIP-25, the standard for registering AI agents to ENS names.

Domain owners can set agent-registration text records on their ENS name to cryptographically link AI agents to their identity — configurable directly from the Records Editor, no manual ABI encoding. When viewing any domain that has ENSIP-25 registrations, you will see a verification card showing the registered agents, their registry addresses, and agent IDs.

Profile completeness score

Ever wondered how complete your ENS profile is? Now there is a score for it. When viewing your own domain, you will see a circular completeness indicator that checks for avatar, description, website, email, social handles, ETH address, multi-chain addresses, content hash, and primary name. Each item is weighted by importance, and a "Complete your profile" button takes you straight to the editor.

Multi-chain addresses (ERC-7828)

ENS isn't just for Ethereum any more. We now display multi-chain addresses using the ERC-7828 name@chain format — the emerging standard for cross-chain resolution. vitalik.eth@optimism, vitalik.eth@base, and the full chain registry from the on.eth convention all surface on the domain detail page.

Direct ENS contract renewals

Renewals now go through the official ENS contracts — no intermediary, no wrapper, no custody. Single renewals use the ETH Registrar Controller; bulk renewals use the official Bulk Renewal contract; the 5% platform fee is transparently routed to enstools.eth. Every transaction you sign hits the ENS protocol directly on mainnet.
