Goalie IP Trademark Search (USPTO + Canada) MCP server

Trademark MCP Server (USPTO)

A remote Model Context Protocol server that lets an AI agent search and filter 14M+ US federal trademark records — by mark text, owner, goods/services, class, status, date, and every other searchable field on the record — then pull any full record by serial number.

Point Claude, Cursor, or any MCP client at one URL. No integration code, nothing to install, and free to start: 200 calls/month, no credit card.

translations, and transliterations — the places near-conflicts hide.

• Search, not lookup. Find the marks you don't already have serial numbers for.
• Catches the variants. Fuzzy matching, plus the USPTO's own pseudo-mark field (GR8 → GREAT),

annotations can run a dozen searches without a confirmation prompt on each one.

• Runs without babysitting. Every tool is declared read-only, so clients that honor tool

want one for scripts and CLI.

Not another TSDR wrapper

Most "trademark MCP" servers wrap the USPTO's TSDR endpoint, which returns a single record only when you already know its serial or registration number. That's a lookup tool. This server searches and filters the whole register, so your agent can find the marks it doesn't already have the numbers for.

See examples/prompts.md for two real sessions — including a ten-name clearance screen that a lookup-only tool cannot begin, because no serial numbers are known going in.

Quickstart (Claude Code)

No key needed — one command, then sign in:

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

Claude Code opens a browser to sign in with your Goalie IP account over OAuth. No account yet? Sign up free — 200 calls/month, no credit card; just confirm your email to activate.

Prefer a key, for scripts or CI? Create one in your Goalie IP portal and pass it as a header:

claude mcp add --transport http goalieip \
  https://www.goalieip.com/api/mcp \
  --header "Authorization: Bearer gip_live_your_key_here"

Then just ask — the agent picks the tool and filters on its own:

> Are there any live trademarks similar to "GOALIE" for software in class 9?
