Implementation Reference
- src/index.ts:871-899 (handler)The function that implements the core logic of the 'save_unmarked_screenshot' tool. It optionally generates a resourceName, unmarks the page to remove bounding boxes, captures a screenshot, stores it in the 'screenshots' map, and returns a success message with the resource URI.
async function handleSaveUnmarkedScreenshot( page: Page, args: any ): Promise<CallToolResult> { let { resourceName } = args; if (!resourceName) { resourceName = `unmarked_screenshot_${Date.now()}`; } // Unmark the page to remove bounding boxes await page.evaluate(() => { if (typeof (window as any).unmarkPage === "function") { (window as any).unmarkPage(); } }); const buffer = await page.screenshot(); screenshots.set(resourceName, Buffer.from(buffer)); return { isError: false, content: [ { type: "text", text: `Unmarked screenshot saved as resource screenshot://${resourceName}`, }, ], }; } - src/index.ts:585-595 (schema)Input schema definition for the tool, specifying an optional 'resourceName' parameter of type string.
inputSchema: { type: "object", properties: { resourceName: { type: "string", description: "The name under which the unmarked screenshot will be saved as a resource (e.g. 'before_login'). If not provided, one will be generated.", }, }, required: [], }, - src/index.ts:581-596 (registration)The tool registration entry in the TOOLS array, including name, description, and inputSchema, which is returned by the ListTools MCP handler.
