- src/playwright_server/server.py:238-248 (handler)The ClickToolHandler class implements the core logic for the 'playwright_click' tool. It clicks on the element matching the provided CSS selector using Playwright's page.locator().click() method.class ClickToolHandler(ToolHandler): @update_page_after_click async def handle(self, name: str, arguments: dict | None) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: if not self._sessions: return [types.TextContent(type="text", text="No active session. Please create a new session first.")] session_id = list(self._sessions.keys())[-1] page = self._sessions[session_id]["page"] selector = arguments.get("selector") await page.locator(selector).click() return [types.TextContent(type="text", text=f"Clicked element with selector {selector}")]
