Implementation Reference
- index.js:812-840 (handler)Implements the core logic for the 'get_selected_element' tool by evaluating JavaScript in the browser to retrieve details of the currently active DOM element (document.activeElement), including tag name, ID, class, text content, value, and a generated selector.
async getSelectedElement() { await this.ensureChromium(); const result = await this.sendCDPCommand('Runtime.evaluate', { expression: ` const activeElement = document.activeElement; if (activeElement && activeElement !== document.body) { JSON.stringify({ tagName: activeElement.tagName, id: activeElement.id, className: activeElement.className, textContent: activeElement.textContent?.substring(0, 100), value: activeElement.value || null, selector: activeElement.id ? \`#\${activeElement.id}\` : activeElement.className ? \`.\${activeElement.className.split(' ')[0]}\` : activeElement.tagName.toLowerCase() }); } else { null; } `, returnByValue: true }); const selectedElement = result.result?.value ? JSON.parse(result.result.value) : null; return { content: [{ type: 'text', text: selectedElement ? JSON.stringify(selectedElement, null, 2) : 'No element currently selected' }], }; } - index.js:271-278 (registration)Registers the 'get_selected_element' tool in the list of available tools returned by ListToolsRequestSchema, specifying its name, description, and empty input schema (no parameters required).
{ name: 'get_selected_element', description: 'Get information about the currently selected element', inputSchema: { type: 'object', properties: {}, }, }, - index.js:274-277 (schema)Defines the input schema for the 'get_selected_element' tool as an empty object (no required parameters).
inputSchema: { type: 'object', properties: {}, }, - index.js:377-378 (handler)Dispatch handler in the CallToolRequestSchema switch statement that routes calls to the getSelectedElement method.
