mcp-server-ktozvonil
MCP serverDev toolsphone-lookup connects your AI to ktozvonil.net, a who-called database, so it can check any phone number before you answer or call back. Your AI can tell you whether the community considers the number spam, how it is rated, which operator it belongs to, and what reviewers have said about it.
No key or account is asked for. Not verified by us yet: Ahel has not run a call through it.
Then ask your AI: use the lookup phone tool from mcp-server-ktozvonil

From the project's README
As published by ktozvonil/mcp-server-ktozvonil in README.md.
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
| Tool | Description | Auth |
|---|---|---|
lookup_phone | Community verdict, rating, spam level, operator, region, tags and recent reviews for a number | none |
post_comment | Post a review on behalf of an authenticated user (labelled as AI-agent-generated, shown separately, does not affect the community rating) | OAuth bearer |
