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
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
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.
