:::note
These steps follow the client's own MCP documentation, linked in Sources below. looot has not tested them in this client yet. If a step fails, tell us on the [support page](/support).
:::
Open WebUI is a self-hosted chat front end. Native MCP support is Streamable HTTP only and arrived in v0.6.31, which is looot's transport. An admin adds the connection.
Before you start you need a looot account. The runs you make spend the organization's balance, so
top up before your first paid run. See [Before your first run](/money#before-your-first-run).
## Steps
1. As an admin, open **Settings, Admin, Integrations**. Under **External Tool Servers**, click **+ Add Connection**.
2. Set **Type** to **MCP (Streamable HTTP)**.
3. Enter the URL `https://api.looot.ai/mcp` and a name such as `looot`.
4. Set **Auth** to **OAuth 2.1** (dynamic client registration if offered, static otherwise) and save.
5. In a chat, enable the tool for that chat and sign in when asked.
The server URL is `https://api.looot.ai/mcp`.
## Sign-in
Open WebUI supports OAuth 2.1 with dynamic client registration or with a static client, plus bearer tokens. Use OAuth so each user signs in on looot.ai and picks the organization to bill. With a static client you must register it yourself first, which is why dynamic registration is easier.
## Check it works
Ask Open WebUI to call [`balance`](/mcp-tools/balance) or [`catalog_overview`](/mcp-tools/catalog-overview). Both are free. A working connection answers
with your available balance, or the catalog's categories and job counts.
## A first prompt to try
```text
Ask looot for my balance, then search its catalog for a tool that finds a work email from a name and company domain, and show me the price before running anything.
```
## Troubleshooting
- Connection type missing: you are below v0.6.31. Update first.
- A tool that uses OAuth 2.1 and is set as a model's default tool can fail. Remove it from the model's default tools and enable it per chat (a known Open WebUI limit).
- Open WebUI must reach `api.looot.ai` from the server, not just from your browser.
- Still stuck: see [Troubleshooting](/connect/troubleshooting).
## What you see when you connect
If the client uses browser sign-in, it opens looot.ai and shows the consent page: which organization to bill,
which scopes to grant and how long to stay connected. See [The consent page](/connect#the-consent-page).
