## Overview

Open WebUI v0.6+ supports seamless integration with external tools via the OpenAPI servers — meaning you can easily extend your LLM workflows using custom or community-powered tool servers 🧰.

In this guide, you'll learn how to launch an OpenAPI-compatible tool server and connect it to Open WebUI through the intuitive user interface. Let’s get started! 🚀

---

## Step 1: Launch an OpenAPI Tool Server

To begin, you'll need to start one of the reference tool servers available in the openapi-servers repo. For quick testing, we’ll use the time tool server as an example.

🛠️ Example: Starting the `time` server locally

```bash
git clone https://github.com/open-webui/openapi-servers
cd openapi-servers

# Navigate to the time server
cd servers/time

# Install required dependencies
pip install -r requirements.txt

# Start the server
uvicorn main:app --host 0.0.0.0 --reload
```

Once running, this will host a local OpenAPI server at http://localhost:8000, which you can point Open WebUI to.

## Step 2: Connect Tool Server in Open WebUI

Next, connect your running tool server to Open WebUI:

1. Open WebUI in your browser.
2. Open ⚙️ **Settings**.
3. Click on ➕ **Tools** to add a new tool server.
4. Enter the URL where your OpenAPI tool server is running (e.g., http://localhost:8000).
5. Click "Save".

## Step 3: Confirm Your Tool Server Is Connected ✅

Once your tool server is successfully connected, Open WebUI will display a 👇 tool server indicator directly in the message input area:

📍 You'll now see this icon below the input box:

Clicking this icon opens a popup where you can:

- View connected tool server information
- See which tools are available and which server they're provided by
- Debug or disconnect any tool if needed

🔍 Here’s what the tool information modal looks like:

## Need More Tools? Explore & Expand! 🧱

The openapi-servers repo includes a variety of useful reference servers:

- 📂 Filesystem access
- 🧠 Memory & knowledge graphs
- 🗃️ Git repo browsing
- 🌎 Web search (WIP)
- 🛢️ Database querying (WIP)

You can run any of these in the same way and connect them to Open WebUI by repeating the steps above.

## Troubleshooting & Tips 🧩

- ❌ Not connecting? Make sure the URL is correct and accessible from the browser used to run Open WebUI.
- 🔒 If you're using remote servers, check firewalls and HTTPS configs!
- 📝 To make servers persist, consider deploying them in Docker or with system services.
