WHAT IT DOES

What browser_select_option does on Playwright MCP

AI agents invoke browser_select_option to trigger actions in Playwright MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
