One1 Trademark Risk Check — MCP Server

Pre-listing trademark checks for cross-border e-commerce sellers, right inside your AI assistant.
Data provided by Dataify.

Official MCP Registry: cn.one1/trademark · one1.cn · 中文说明

Ask your AI assistant things like:

• "Is the brand name Lumora already registered in the US?"
• "Does this Amazon title contain infringing trademarks: Wireless Earbuds Compatible with AirPods"
• "Is this logo similar to any registered trademark?" (image URL)
• "Does YETI frequently file TRO / Schedule A lawsuits against sellers?"
• "I got an infringement complaint citing US serial 78414956 — who is it?"

One1 searches tens of millions of trademark records across dozens of jurisdictions — roughly 32.8M text marks and 57.5M figurative marks — plus a curated list of frequent TRO / Schedule A enforcers.

Tools

All tools accept country (ISO 3166-1 alpha-2, default US).

Reading results correctly

• trademark_text_search.count is the number of nearest neighbours returned (always equals limit), not the number of conflicts. Use has_conflicts / conflict_count.
• Call coverage_info first. Where clearance_ok is false, "no match" does not mean a mark is registrable.
• Results are for reference only and do not constitute legal advice.

Skills

skills/ contains ready-made workflows (Agent Skills format) that tell an assistant how to chain the tools:

Pricing

Usage is metered in API points on your One1 account. The free plan includes a monthly allowance; coverage_info is always free. See one1.cn.
