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

​
What it does

This tool lets a Claude agent look up current information on the web while it responds. It uses Anthropic’s native web_search server tool, so no separate MCP server is required.

​
Requirements

Anthropic Web Search is only available when your agent is configured to use an Anthropic model. Your Anthropic organization must also have web search enabled in Anthropic’s console.

​
Adding the tool to an agent

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

​
Configuration

Anthropic Web Search has two settings:
  • Max Uses: the maximum number of Anthropic web search requests the model may perform during a single response. The default is 3, and the maximum is 20.
  • Location Country: a two-letter country code used to localize search results. The default is US. FetchHive sends this as Anthropic’s approximate user_location.country.
FetchHive sends Anthropic’s web_search_20260209 server tool and Anthropic handles search execution and citations.

​
Use cases

  • Look up current events or recent news using a Claude agent.
  • Check live web sources before the agent answers a question.
  • Ground agent responses with cited public web sources.

​
Notes

  • This tool is powered by Anthropic’s native web_search capability, not an external MCP server.
  • Search calls are billed as Anthropic web search requests in addition to normal model token usage.
  • Anthropic does not expose FetchHive’s agent-level Max Tool Calls request parameter. Use this tool’s Max Uses setting to limit native web search calls.
  • Use Chat in the editor to see when the agent calls Anthropic Web Search during a test run. See Testing with Chat.
