One1 Trademark Risk Check — MCP Server

---

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.

{
  "mcpServers": {
    "one1": {
      "type": "streamable-http",
      "url": "https://one1.cn/mcp",

Tools

Tool	What it does
trademark_text_search	Brand name / word vs. registered trademarks (phonetic, visual and semantic similarity)
listing_scan	Finds trademark-infringing words in a product title or listing copy, grouped by risk
graphic_trademark_search	Reverse image search for similar registered figurative marks (public image URL)
trademark_lookup_by_serial	Trademark details, legal status and risk by serial number
trademark_owner_search	Trademarks held by an owner / applicant
trademark_owner_profile	Whether an owner is a frequent TRO / Schedule A enforcer
coverage_info	Data coverage and freshness per jurisdiction (free)

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:

Skill	Use it when
trademark-preflight	Checking a brand name and listing title before going live
logo-conflict-check	Checking whether a logo looks like a registered mark
tro-risk-check	Handling an infringement complaint or a TRO worry

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.
