NameWhisper MCP Server
Enables on-chain management of ENS domains on the Ethereum blockchain, including registration, renewal, transfers, wrapping, and trading via signed Seaport transactions.
Searches Farcaster casts as part of the knowledge tool, allowing agents to query community discussions and social data.
Uses Wikidata for entity recognition in name valuations, helping identify real-world entities to improve pricing estimates.
Uses Wikipedia for entity recognition in name valuations, helping identify real-world entities to improve pricing estimates.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@NameWhisper MCP ServerFind me 3-letter .eth names listed below valuation"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
NameWhisper MCP Server
AI-powered ENS intelligence for autonomous agents. Search 3.5M+ names, get valuations, trade, and manage ENS domains — all via the Model Context Protocol.
Quick Start
Claude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"namewhisper": {
"command": "npx",
"args": ["-y", "namewhisper-mcp"]
}
}
}Cursor
Add to .cursor/mcp.json in your project root:
{
"mcpServers": {
"namewhisper": {
"command": "npx",
"args": ["-y", "namewhisper-mcp"]
}
}
}Claude Code
claude mcp add namewhisper -- npx -y namewhisper-mcpDirect Usage
npx namewhisper-mcpRemote endpoint (no install)
The same 44 tools are served directly over streamable HTTP — point any remote-capable MCP client at:
https://namewhisper.ai/mcpFor Claude Code:
claude mcp add --transport http namewhisper https://namewhisper.ai/mcpServer card: namewhisper.ai/.well-known/mcp.json · Registry: ai.namewhisper/ens-tools on the MCP Registry

What It Does
NameWhisper exposes 44 ENS tools over the Model Context Protocol, giving AI agents full access to:
Search — natural language queries across 3.5M+ indexed ENS names with semantic vector search
Valuation — confidence-rated price estimates using comparable sales, entity recognition, and quality signals
Marketplace — browse listings, find underpriced names, check recent sales and offers
Commerce — register names, list names for sale, buy listings (single or batch up to 20), make offers, accept offers, cancel listings and offers, bulk register up to 20 names in 2 transactions
Management — renew, transfer, set records, wrap/unwrap, manage fuses, create subnames
Agent Identity — provision ENSIP-25 agent identities, check ERC-8004 reputation, search the agent directory
Knowledge — search ENS governance proposals, protocol docs, and community discussions

└─────────────────┘This package is a thin proxy. It registers tool schemas locally for your MCP client to discover, then forwards all tool calls to the NameWhisper backend at namewhisper.ai/mcp. The proprietary valuation engine, marketplace aggregation, database, and on-chain transaction building all run server-side.
No API key required. No database. No secrets. Just npx and go.
Tools Reference
Discovery
Tool | Description |
| Natural language search with automatic intent detection — filtered, semantic, creative, or bulk availability check |
| Verified, correctly-spelled label list for a real-world entity category (e.g. "F1 world champions"), grouped by available vs registered |
| Full metadata for a name: owner, expiry, tags, listings, offers, ENSIP-25 agent bindings |
| Bulk check registration status for multiple names |
| Semantic vector search across 3.5M+ names using 256-dim embeddings |
| Names by lifecycle window — premium (Dutch auction), grace period, or expiring soon, validated on-chain |
Intelligence
Tool | Description |
| Three-track valuation: comp-based + quality-reference + self-history. Entity recognition via Wikipedia/Wikidata |
| Recent sales, listings, offers, mints, transfers, renewals, burns |
| All ENS names owned by a wallet with listings, offers, and expiry data |
| Discover names listed below comparable-sales valuation with discount % and confidence |
| Detect wash trading in ENS sales using on-chain analysis |
| Reverse resolution — check what ENS name is set for a wallet address |
Commerce
Tool | Description |
| Register available names or buy listed names. Auto-detects action, returns transaction recipes |
| Buy up to 20 NameWhisper-listed names in one Seaport transaction |
| Floor-sweep the cheapest N names in a category/filter (bounded by count and/or budget) in one Seaport transaction |
| List a name for sale on NameWhisper. Builds unsigned Seaport order for signing |
| Bulk-list up to 10 names on NameWhisper in one signing flow (SIP-6 bulk signature) |
| Cancel an active listing via Seaport.cancel() on-chain — invalidates the order across all venues |
| Submit a bid on a registered name with market context |
| Seller-side acceptance of a standing offer. Atomic WETH↔name swap via Seaport.fulfillOrder() |
| Cancel an offer you made via Seaport.cancel() on-chain |
| Batch register up to 20 names in 2 transactions (commit + register) via Multicall3 |
| Renew single or batch names. Any duration, anyone can renew any name |
| Set resolver records across up to 50 names in one transaction |
Management
Tool | Description |
| Transfer ownership (auto-detects wrapped vs unwrapped) |
| Batch transfer up to 20 names in 1 transaction via Multicall3 |
| Set address records, text records, content hash, ENSIP-25 agent registration |
| Set reverse resolution (primary name) for a wallet |
| Change resolver contract |
| Comprehensive status check with renewal pricing and recommendations |
NameWrapper
Tool | Description |
| Wrap into NameWrapper (ERC-721 to ERC-1155) with optional fuse burning |
| Unwrap back to BaseRegistrar (ERC-1155 to ERC-721) |
| Read or burn fuses on wrapped names (irreversible) |
| Bulk create subnames under a parent name |
| Extend subname expiry within parent bounds |
Access & Recovery
Tool | Description |
| Approve/revoke operator for ENS contracts (setApprovalForAll) |
| Reclaim ENS Registry ownership from BaseRegistrar token |
Agent Identity
Tool | Description |
| One-call agent identity setup: name recommendations + registration recipe + ENSIP-25 records |
| Register an ENS name as an ERC-8004 agent identity on mainnet (ERC-8217 name-bound or direct-to-wallet) |
| Check ENSIP-25 agent-registration verification + ERC-8004 reputation |
| Find registered AI agents by capability, reputation, or name |
| Returns authenticated identity of the calling agent (requires ERC-8128) |
Knowledge & Internal
Tool | Description |
| Search ENS governance, protocol docs, blog posts, forum discussions, Farcaster casts |
| Session tool call counts, success rates, and latency |
Configuration
Environment Variable | Default | Description |
|
| Backend URL (override for local development) |
Copy .env.example to .env to customize. Most users need no configuration.
