# OpenFile with Cursor

Source: https://joinopenfile.com/docs/agents/cursor
Index: https://joinopenfile.com/llms.txt

Connect Cursor to the OpenFile [MCP server](https://joinopenfile.com/docs/mcp.md) and it can check names, price filings and prepare them. It needs no key or account.

## Connect

[Add OpenFile to Cursor](cursor://anysphere.cursor-deeplink/mcp/install?name=openfile&config=eyJ1cmwiOiJodHRwczovL21jcC5qb2lub3BlbmZpbGUuY29tIn0=), or put this in `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "openfile": {
      "url": "https://mcp.joinopenfile.com"
    }
  }
}
```

## Try it

Ask Cursor something like:

- "Form a Wyoming LLC for my candle business."
- "Is QUILLBROOK likely to be refused as a trademark for candles?"
- "What would it cost to file a trademark in two classes?"
- "Where is my order?"

Cursor calls `plan_task` first, so it asks the person what it needs instead of guessing.

## What you still do yourself

Cursor prepares the draft and sends the owner a link. They open it, check every answer and sign. An agent can't sign for them, and it never handles a Social Security number. [Why the owner signs](https://joinopenfile.com/docs/mcp.md#how-an-agent-files).

## Check it worked

Ask Cursor to list its OpenFile tools. You should see `plan_task`, `create_formation` and `search_docs`.
