# Ask Hagglyai from the Claude chat box

You don't need to write code to use Hagglyai. Add it to the Claude app as a connector, then ask in plain English which paid API to use for a job, what it costs and whether it's reliable.

## 1. Add Hagglyai to Claude

### In the Claude app (chat box)

1. In Claude, go to **Customize > Connectors**.
2. Click **+ Add**, then **Add custom connector**.
3. Name it **Hagglyai** and enter the server URL `https://hagglyai.com/mcp`, then click **Continue** twice.
4. Under Authentication choose **No sign in** (Hagglyai needs no account or key), then click **Add**.
5. In a chat, click **+** in the lower left, choose **Connectors** and turn **Hagglyai** on.
6. Type your question in the chat box. If Claude asks before using a Hagglyai tool, allow it.

Pro and Max add connectors themselves; Free plans can have one custom connector; on Team and Enterprise an owner adds it and members click Connect. Once added it also works in the desktop and mobile apps.

### In Claude Code (one line)

```sh
claude mcp add --transport http haggly https://hagglyai.com/mcp
```

Any other MCP client: add the server `https://hagglyai.com/mcp` (Streamable HTTP, no key). More at https://hagglyai.com/for-agents.

## 2. Ask

> What's the cheapest reliable weather API right now?

Claude calls `find_best` with:

```json
{
  "task": "weather"
}
```

## 4. How to read it

- Claude reads Hagglyai's answer and replies in plain words: the recommended API, its price per lookup and its score out of 100, with alternatives.
- Follow up in the same chat: "compare the top five" runs `compare_category`, "check this endpoint before I pay" runs `check_endpoint`.
- The connector is read-only: Hagglyai never calls or pays an API for you, it tells you which one to use.
