# OpenFile with Devin Desktop

Index: https://joinopenfile.com/llms.txt

Connect Devin Desktop 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

Run this once:

```bash
devin mcp add openfile https://mcp.joinopenfile.com
```

Or put this in `~/.config/devin/mcp_config.json`:

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

## Try it

Ask Devin Desktop 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?"

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

## What you still do yourself

Devin Desktop 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 Devin Desktop to list its OpenFile tools. You should see `plan_task`, `create_formation` and `search_docs`.
