How to Use the USPTO API MCP in Cursor

Q: How do I use USPTO API within Cursor for coding?

You enable Agent mode and call tools like searchpatents in your prompt. The AI then recognizes the live data returned from the USPTO API and injects it as a real variable into the code you're writing.

Q: Can I check trademark details using USPTO API via Cursor?

Yes, use gettrademarkdetails. You give the serial number to the agent in your chat, and it calls the tool. The live result is then available for you to incorporate into your current code file.

Q: Is the USPTO API reliable when working inside Cursor?

The system uses the checkapistatus tool, which confirms the operational status of the USPTO Open Data API. This lets you trust that the data source is live before your code runs.

Write code that calls USPTO API tools directly in Cursor for real-time IP context.

Inject live patent data into your function

When you write code, use the `search_patents` tool to get current US patent results. The AI agent then generates working Python or Javascript that uses these real API responses directly in your code block. This means your script doesn't rely on mock data; it gets live context from the USPTO API and you can see exactly how the result set fits into your program’s logic.

Automate IP checks mid-coding

The `get_trademark_details` tool lets you check a specific trademark serial number right while you're writing code. You can prompt the agent, and it will fill in the function body with real data retrieved from the USPTO API. This flow keeps your context locked on the editor; you never have to switch away from Cursor to verify an IP asset.

Structure searches using classification codes

Start by calling `list_patent_classes` to understand the available patent codes. Then, feed those specific classes into a targeted `search_patents` call. The AI generates the structured code needed for this complex multi-step process. This capability is crucial when you need to narrow down a search beyond just keywords, making your IP audits much more precise.

Setup guide

Set up USPTO API MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the USPTO API MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent USPTO API transactions." If the MCP tools are loaded correctly, Cursor will call the USPTO API tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "uspto-api-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}
