Goalie IP Trademark Search (USPTO + Canada)

Goalie IP Trademark MCP Server (USPTO + Canada)

A hosted trademark MCP server for Claude, ChatGPT, Cursor, or any MCP client. One endpoint lets an agent search the U.S. and Canadian federal trademark registers, screen a proposed name, retrieve full records, check upcoming deadlines, and find acceptable goods and services wording.

Goalie IP searches its own copies of the registers: a daily-refreshed copy of 14M+ USPTO applications and registrations, and a weekly-refreshed copy of 2.2M+ Canadian (CIPO) filings. The server is ready to use: no package to install, integration code to write, or database to run.

• Screen a proposed name in one call. Find exact matches, spelling variants, sound-alikes (KWIK vs. QUICK), and the USPTO's own pseudo-mark readings (EZ as EASY), in the U.S. or Canada.
• Search the register, not just known serial numbers. Filter by mark, owner, goods/services, class, status, dates, attorney, and more.
• Get deadline answers from a purpose-built tool. Check one serial number or upcoming dates across an owner's marks or an attorney's docket.
• Draft the goods and services. Look up pre-approved wording and classes in the USPTO ID Manual.
• Let agents work without babysitting. All seven tools are declared read-only.

More than a TSDR lookup

TSDR returns a record when you already know its serial or registration number. Goalie IP lets an agent begin with the question the user actually has: *Is this name taken? What has this owner filed? Which marks cover these goods? What is due next? How should I describe my goods?*

Claude and ChatGPT directories

Goalie IP is listed in the Claude Connectors Directory and the ChatGPT plugins directory (search for Goalie). Install it there and sign in with your Goalie IP account.

Claude Code

claude mcp add --transport http goalieip https://www.goalieip.com/api/mcp

Claude opens a browser for OAuth sign-in. No API key is required.

Claude Desktop and claude.ai (custom connector)

Open Settings → Connectors → Add custom connector, then paste:

https://www.goalieip.com/api/mcp

Cursor, scripts, and CI

For clients without OAuth, create an API key in the Goalie IP portal. Drop-in configurations are in examples/, with complete setup and troubleshooting at goalieip.com/docs#mcp.

Always use the www host. Some clients drop authorization headers when following the redirect from goalieip.com to www.goalieip.com.

Seven read-only tools

All seven tools are annotated readOnlyHint: true. The five data tools are metered; get_data_status and get_account are not. For complete descriptions and input schemas, see the live server card.

find_similar_marks is a screening aid, not a clearance search or legal opinion. It returns strong matches—more when the field is crowded—with dead marks listed separately. For register research by owner, goods, dates, or other fields, use search_trademarks.

Coverage and trust

• U.S. and Canadian federal records only. The tools cover USPTO and CIPO applications and registrations, one register per call. They do not search state or provincial registrations, unregistered common-law use, other trademark offices, the web, marketplaces, social media, or domain names. Deadlines and the ID Manual are U.S. only.
• Goalie IP's copy of the registers. U.S. data is refreshed daily and Canadian data weekly, so a very recent filing may not appear yet. This is not a live connection to USPTO or CIPO systems. Goalie IP is not affiliated with or endorsed by the USPTO or CIPO.
• Canadian attribution. Canadian results carry CIPO's attribution statement: *Contains data licensed by Her Majesty the Queen in right of Canada, as represented by the Minister of Industry, the minister responsible for the administration of the Canadian Intellectual Property Office.*
• Data, not legal advice. Results do not decide registrability, likelihood of confusion, or infringement, and using the tools does not create an attorney-client relationship.
• Public-record text is untrusted input. Mark text, owner names, and goods/services descriptions come from public filings. Tool responses fence and label record content, but builders should apply their own checks before allowing it to drive privileged actions.

For an attorney-led opinion or enforcement work, contact the Goalie IP team.

Privacy

The server records one usage row per metered call—the credential identifier, tool, status code, and timestamp—for allowance enforcement, billing, and abuse detection. Query contents are not stored, and conversation prompts and files do not reach the server. OAuth tokens are stored only as hashes and can be revoked from the account portal.
