# OpenFile with Langflow

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

Connect Langflow 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

Open **Settings**, then **MCP Servers**, press **Add MCP Server** and pick **HTTP/SSE**. Set the **Name** to OpenFile and the **URL** to this address, leave **Headers** empty, and save:

```text
https://mcp.joinopenfile.com
```

## Try it

Your agent can then handle requests 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?"

Have your agent call `plan_task` first, so it asks the person what it needs instead of guessing.

## What you still do yourself

Your agent 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

List the tools it loaded. You should see `plan_task`, `create_formation` and `search_docs`.
