WHAT IT DOES

What screenshot does on Playwright MCP Server

AI agents call screenshot to retrieve information from Playwright MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why screenshot is rated Low

A screenshot retrieves and returns visual content from a rendered page. This is a read-only operation with no side effects, no data modification, and no irreversible consequences. While it can extract information from web pages, it does not execute arbitrary commands, delete data, or move money.

From the tool's definition Tool named 'screenshot' on a Playwright browser automation server. Screenshot operations capture the current visual state of a webpage without modifying data, executing code, or triggering external actions.

  "tools": {
    "screenshot": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.
