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
| 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 |
