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

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.
