Overview

AI-generated overview

Hosted MCP server that lets an assistant check brand names, logos and product listings against registered trademarks and TRO enforcers.

What you can do
  • Search brand names and words against registered trademarks by phonetic, visual and semantic similarity
  • Scan product titles or listing copy for infringing words, grouped by risk
  • Reverse image search for similar registered figurative marks from a public image URL
  • Look up trademark details, legal status and risk by serial number, or list marks held by an owner
  • Check whether an owner is a frequent TRO / Schedule A enforcer
  • Report data coverage and freshness per jurisdiction
When to use it
Useful for cross-border e-commerce sellers who want a pre-listing check of a brand name, logo or Amazon-style listing title, or who received an infringement complaint and need to identify the cited mark or its owner.
Requirements
Remote hosted endpoint over Streamable HTTP; nothing to install. Authorization is required to call tools: OAuth 2.1 with dynamic client registration and PKCE, or an API key sent in the X-Api-Key header created on the provider's developer site. A One1 account is needed for metered usage.
Before you install
Usage is metered in API points against a One1 account, with a free monthly allowance; paid usage may incur cost. Tool calls require sign-in or an API key, so keep the key secret. Queries, including image URLs and listing text, are sent to the provider and its data supplier. Results are reference only, not legal advice, and where coverage is incomplete a no-match does not mean a mark is registrable.

Installation

In SourceWeft

  1. Open One1 Trademark Risk Check in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cn.one1%2Ftrademark/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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

ToolWhat it does
trademark_text_searchBrand name / word vs. registered trademarks (phonetic, visual and semantic similarity)
listing_scanFinds trademark-infringing words in a product title or listing copy, grouped by risk
graphic_trademark_searchReverse image search for similar registered figurative marks (public image URL)
trademark_lookup_by_serialTrademark details, legal status and risk by serial number
trademark_owner_searchTrademarks held by an owner / applicant
trademark_owner_profileWhether an owner is a frequent TRO / Schedule A enforcer
coverage_infoData 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
