Wait for the next download event and return its metadata.
AI agents call browser.wait_for_download to retrieve information from MCP Playwright Browser without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool passively observes and retrieves download event metadata. It performs no write operations, does not execute arbitrary code or commands, does not delete data, and does not move funds. The action is purely informational (Read category). The severity is low because metadata retrieval poses minimal risk even if misused by an AI agent — it cannot trigger unwanted downloads or cause secondary harm.
From the tool's definition Tool description states 'Wait for the next download event and return its metadata' — it retrieves and returns metadata about a download without modifying, executing code, or initiating downloads itself.
