Playwright MCP Tools and Capabilities — quiz

Why does Playwright MCP default to snapshot (accessibility-tree) mode rather than sending raw screenshots for every interaction?

• Screenshots are not supported by any LLM
• The accessibility tree is a structured, text-based representation of the page that is far cheaper to send, deterministic to parse, and gives the model stable role/name references for elements — leading to more accurate clicks and lower token cost than image-based reasoning
• Screenshots are illegal to send to LLMs
• Snapshots are only used in headless mode
