Takes a screenshot of the current page. Use this tool to learn where you are on the page when controlling the browser with Stagehand. Only use this tool when the other tools are not sufficient to get the information you need.
AI agents call browserbase_screenshot to retrieve information from Browserbase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Taking a screenshot captures visual data from the current browser state without modifying, deleting, or executing any operations on the target system. This is a read-only observation capability analogous to viewing a webpage. No data is modified, deleted, or financial transactions initiated.
From the tool's definition Tool description states 'Takes a screenshot of the current page' and is explicitly positioned as a tool to 'learn where you are on the page' — a pure observation/information retrieval action with no side effects.
