# Web Tools

> Tools for fetching URLs and searching the web.

Web tools give Claude the ability to retrieve information from the internet — fetching documentation, searching for solutions, and reading external resources.

## WebFetchTool

Fetches the content of a URL and returns it as text or markdown. Useful for reading documentation, API specs, or any web page.

**Usage pattern:**

```
> Fetch the React hooks documentation and explain useCallback
> Get the latest changelog from the express npm page
> Read this Stack Overflow answer: https://...
```

**Supported content:**

* Web pages (returned as markdown)
* Plain text files
* HTML pages (converted to readable text)
* JSON APIs

<Note>
  WebFetchTool requires network permission. On first use, Claude will ask for your approval to make web requests.

## WebSearchTool

Performs a web search and returns results with titles, URLs, and snippets.

**Usage pattern:**

```
> Search for how to configure Jest with TypeScript
> Find the documentation for the Zod v4 API
> Look up the error "ECONNREFUSED 127.0.0.1:5432"
```

**When Claude uses it:**

* Looking up unfamiliar libraries or APIs
* Finding solutions to error messages
* Checking current best practices
* Locating documentation for dependencies

**Combining with WebFetchTool:**

Claude often uses WebSearchTool to find relevant URLs, then WebFetchTool to read the full content:

1. Search for "Prisma soft delete pattern"
2. Identify the most relevant result
3. Fetch the full page for detailed guidance

<Tip>
  You can tell Claude to search the web explicitly: "Search the web for the best way to handle JWT refresh tokens in Express." Claude will use WebSearchTool automatically when it needs up-to-date information.
