What the publisher says

From the Phone Lookup repository's README, as published. We do not edit it. Read it on GitHub

mcp-server-ktozvonil

MCP (Model Context Protocol) server for ktozvonil.net — a community phone-number reputation service for Ukraine and beyond. Ask your AI assistant "who called me from 050 110 89 01?" and it will answer with the community verdict, spam rating, operator, region, tags and recent reviews.

This package is a thin stdio bridge to the site's native MCP endpoint (https://ktozvonil.net/mcp). Tools are discovered at startup, so the package never goes stale.

Tools

Install

Claude Code

claude mcp add ktozvonil -- npx -y mcp-server-ktozvonil

Claude Desktop

{
  "mcpServers": {
    "ktozvonil": {
      "command": "npx",
      "args": ["-y", "mcp-server-ktozvonil"]
    }
  }
}

Cursor / Windsurf / other MCP clients

Any client that speaks stdio MCP works the same way: command npx, args -y mcp-server-ktozvonil.

Remote (no install)

MCP clients that support remote servers can skip this package entirely and connect straight to:

https://ktozvonil.net/mcp

Configuration

Example

User: Кто звонил с +38 050 110 89 01?

Assistant: (calls lookupphone)* This number has a "spam" community verdict on ktozvonil.net: 78 reports, mostly "intrusive advertising"…

Development

npm install
npm run build
npm test
