Trademark MCP Server (USPTO)

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

Point Claude Code, the Claude API, Cursor, or any MCP client at one URL and your agent can query the US federal trademark register with no integration code to write.

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)

Create an API key in your Goalie IP portal, then:

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?

  Searching US federal trademarks…
  Found 94 matches. 12 are live in class 9, including:
    GOALIEO   — Goalieo Inc      — Live/Pending  — filed 2026-05-29
    …

The two tools

search_trademarks returns compact summaries (page size defaults to 10, capped at 15) sized to sit in a model's context window; call get_trademark for the full record. Every search must include at least one narrowing filter (markLiteral, ownerName, serialNumber, registrationNumber, goodsAndServices, or another text filter) — class, status, and date filters alone match too much of the register to run. When a query is rejected or times out, the tool replies with the specific parameter to change, so the agent can correct itself and retry.

In the MCP Registry

This server is published to the official MCP Registry as com.goalieip/trademark, under a namespace verified against the goalieip.com domain — so the listing is first-party, not a third-party mirror.

curl "https://registry.modelcontextprotocol.io/v0/servers?search=com.goalieip/trademark"

Clients that read the registry can add the server by name, and will prompt for the Authorization header themselves. Clients that don't, use the manual configs below.

Connect from any client

Config files for each client are in examples/. Replace gip_live_your_key_here with a key from your portal.

Claude API (MCP connector)

{
  "mcp_servers": [
    {
      "type": "url",
      "url": "https://www.goalieip.com/api/mcp",
      "name": "goalieip",
      "authorization_token": "gip_live_your_key_here"
    }
  ]
}

Any MCP client / Cursor (generic config)

{
  "mcpServers": {
    "goalieip": {
      "type": "http",
      "url": "https://www.goalieip.com/api/mcp",
      "headers": {
        "Authorization": "Bearer gip_live_your_key_here"
      }
    }
  }
}

Claude Desktop

Claude Desktop's Add connector screen only accepts OAuth, so connect through the small mcp-remote bridge, which attaches your key for you. Full step-by-step (including the "fully quit before editing" gotcha) is at goalieip.com/docs#mcp.

{
  "mcpServers": {
    "goalieip": {
      "command": "cmd",
      "args": [
        "/c", "npx", "-y", "mcp-remote@latest",
        "https://www.goalieip.com/api/mcp",
        "--header", "Authorization:Bearer ${GOALIE_KEY}"
      ],
      "env": { "GOALIE_KEY": "gip_live_your_key_here" }
    }
  }
}

On macOS, drop the "cmd", "/c", entries so the args start at "npx". The bridge needs Node.js. The header is written Authorization:Bearer with no space after the colon so argument parsing doesn't split it.

Server details

Always configure the www host. goalieip.com 301-redirects to www, and many clients drop the Authorization header across the redirect (→ a 401). More troubleshooting: goalieip.com/docs#mcp.

Pricing

MCP access is included with every Goalie IP API plan at no extra cost — it uses the same key and the same monthly quota as the REST API. The free tier is 200 calls/month (no credit card). Compare plans at goalieip.com/subscribe#api.

One note on sizing: agents typically make several tool calls to answer one question, so MCP consumes quota faster than a scripted one-request-per-lookup integration. Budget for that when picking a plan.

Scope & safety

• US federal data only. This is a continuously-refreshed copy of the USPTO trademark register, updated daily and occasionally a day behind. It does not cover US state registrations, unregistered common-law use, or trademark offices outside the United States. Goalie IP is not affiliated with or endorsed by the USPTO.
• Record text is third-party input. Mark text, owner names, and goods/services descriptions are written by whoever filed the application, and every US filing becomes a public record. Tool responses fence that content and label it as data — but if you build your own agent on this data, apply your own checks before letting record text drive tool calls or privileged actions.
• Results are data, not legal advice. These tools return records from the USPTO register. They do not assess registrability, likelihood of confusion, or infringement, and using them creates no attorney-client relationship. For an attorney-led clearance opinion or enforcement work, talk to the Goalie IP team.
