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

Direct Usage
Remote endpoint (no install)
The same 44 tools are served directly over streamable HTTP — point any remote-capable MCP client at:
For Claude Code:
Server 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
Architecture
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.
