Implementation Reference
- src/toolHandler.ts:350-382 (handler)Primary execution logic for 'playwright_close' tool: special case that closes the browser instance if it exists, handles errors, resets global browser state, and returns appropriate success message.
if (name === "playwright_close") { if (browser) { try { if (browser.isConnected()) { await browser .close() .catch((e) => console.error("Error closing browser:", e)); } } catch (error) { console.error("Error during browser close in handler:", error); } finally { resetBrowserState(); } return { content: [ { type: "text", text: "Browser closed successfully", }, ], isError: false, }; } return { content: [ { type: "text", text: "No browser instance to close", }, ], isError: false, }; } - src/tools.ts:209-217 (schema)Tool definition including name, description, and empty input schema (no parameters required). Part of createToolDefinitions() for MCP registration.
{ name: "playwright_close", description: "Close the browser and release all resources", inputSchema: { type: "object", properties: {}, required: [], }, }, - src/tools/browser/navigation.ts:63-91 (handler)Class-based handler implementation for closing browser (CloseBrowserTool.execute). Similar logic to inline handler but not invoked due to early return in toolHandler.ts.
export class CloseBrowserTool extends BrowserToolBase { /** * Execute the close browser tool */ async execute(args: any, context: ToolContext): Promise<ToolResponse> { if (context.browser) { try { // Check if browser is still connected if (context.browser.isConnected()) { await context.browser.close().catch(error => { console.error("Error while closing browser:", error); }); } else { console.error("Browser already disconnected, cleaning up state"); } } catch (error) { console.error("Error during browser close operation:", error); // Continue with resetting state even if close fails } finally { // Always reset the global browser and page references resetBrowserState(); } return createSuccessResponse("Browser closed successfully"); } return createSuccessResponse("No browser instance to close"); } } - src/toolHandler.ts:462-463 (registration)Dispatch registration in handleToolCall switch statement (redundant due to special case above).
case "playwright_close": return await closeBrowserTool.execute(args, context); - src/tools.ts:414-414 (helper)Inclusion in BROWSER_TOOLS array, used to determine browser launch requirements.
