Namewhisper MCP Server

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-mcp

Direct Usage

npx namewhisper-mcp

Remote endpoint (no install)

The same 44 tools are served directly over streamable HTTP — point any remote-capable MCP client at:

https://namewhisper.ai/mcp

For Claude Code:

claude mcp add --transport http namewhisper https://namewhisper.ai/mcp

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

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.
