# xAI Web Search

> Let a Grok-powered agent search the public web using xAI's native web search tool

xAI Web Search gives your agent access to live public web search when it is powered by an xAI Grok model.

## What it does

This tool lets a Grok agent look up current information on the web while it responds. It uses xAI's native `web_search` tool, which is built into the Grok model family — no separate MCP server is required.

## Requirements

xAI Web Search is only available when your agent is configured to use an **xAI (Grok)** model. When your agent uses a different model provider (OpenAI, Anthropic, Google, etc.) use [GPT Search](./gpt-search) or [Google Search](./google-search) instead.

## Adding the tool to an agent

1. Open an agent in the editor.
2. Make sure the agent's model is set to an xAI Grok model.
3. Click the button with the tooltip **Add MCP Tool or Sub Agent**.
4. In **MCP Tools**, click **xAI Web Search**.

## Configuration

xAI Web Search does not have any configuration fields in the settings sheet. The search is handled natively by the Grok model.

## Use cases

* Look up current events or recent news using a Grok agent.
* Check live web sources before the agent answers a question.
* Enrich agent responses with up-to-date information from the public web.

## Notes

* This tool is powered by xAI's native `web_search` capability, not an external MCP server. It is automatically available when an xAI model is selected.
* Use **Chat** in the editor to see when the agent calls **xAI Web Search** during a test run. See [Testing with Chat](../testing-with-chat).
* To add or remove tools from an agent, see [Creating and Configuring](../creating-and-configuring).
