If you've tried "AI clicks the screen" automation, you know the flaky part is usually the vision step. Playwright's MCP server takes a different route: it feeds the model the page's accessibility tree, not a screenshot.

Why this matters

Deterministic: every interactive element gets a stable ref, so the agent targets "this button" instead of guessing from pixels.

Token-efficient: a snapshot is ~200-400 tokens vs thousands for a DOM dump or screenshot.

No vision model required.
