Website Categorization: IAB Categories & Brand Safety

Classify domains into IAB Content Taxonomy 3.1 categories with industry, business model, language and brand safety flags, plus parked, dead and redirected domain detection.

This skill teaches your agent when and how to call the Website Categorization tool on the MessNoMore Data Tools MCP server, with tight cost caps and answers that cite their source.

Ask your agent

• "Which IAB category is shopify.com in, and is it brand safe?"
• "Categorize these 400 domains and flag the parked ones."
• "Label these sites as SaaS, agency, e-commerce or media."

What the skill adds

• Picks the right mode and arguments for the question.
• Caps every run to the results the question needs and asks before any job over about $1.
• Handles runs that take longer than the client waits, without starting duplicates.
• Answers in tables with source links and last-verified dates, flags low-confidence matches and never fills gaps from memory.

Why not just ask your agent?

Models answer questions like these from training data that is months or years old, and they guess codes, dates and registry entries that look right. This skill makes the agent fetch the current record from the source instead, and say so when nothing matches.

Use cases

• Categorize a lead list by industry
• Check publisher brand safety for ad buys
• Remove parked and dead domains from a list
• Map domains to IAB Tier 1 and Tier 2 categories
• Label sites with your own categories
