Implementation Reference
- src/tools/browser_tools.js:402-428 (handler)The main handler function for 'browser_press_key'. It validates the 'key' argument, gets the current page via getPage(), calls page.keyboard.press(key) to simulate a keyboard press, and returns a success/error response.
async function browserPressKey(key) { try { if (!key) { return { success: false, message: 'Key is required' }; } const page = await getPage(); await page.keyboard.press(key); return { success: true, message: `Pressed key: ${key}`, key }; } catch (error) { logger.error(`Error pressing key: ${error.message}`); return { success: false, message: error.message }; } } - src/mcp/server.js:127-135 (registration)Registration: 'browser_press_key' is added to the list of browser extra tools in the MCP server tool registry (line 129). A tool entry with name 'browser_press_key' and a basic description is pushed into the tools array.
const browserExtras = [ { n:'browser_navigate_back' }, { n:'browser_navigate_forward' }, { n:'browser_hover' }, { n:'browser_drag' }, { n:'browser_select_option' }, { n:'browser_press_key' }, { n:'browser_snapshot' }, { n:'browser_console_messages' }, { n:'browser_network_requests' }, { n:'browser_tab_list' }, { n:'browser_tab_new' }, { n:'browser_tab_select' }, { n:'browser_tab_close' }, { n:'browser_file_upload' }, { n:'browser_wait' }, { n:'browser_wait_for' }, { n:'browser_resize' }, { n:'browser_handle_dialog' } ]; for (const b of browserExtras) { tools.push({ name: b.n, description: b.n.replace(/_/g,' '), inputSchema: { type:'object', properties:{} } }); - src/mcp/server.js:282-282 (registration)Dispatch/case handler: In the MCP server's tool call dispatch, the case 'browser_press_key' delegates to browserTools.browserPressKey(args.key).
case 'browser_press_key': data = await browserTools.browserPressKey(args.key); break; - src/tools/browser_tools.js:1139-1145 (helper)Export: browserPressKey is exported from the browser_tools module (line 1139) so it can be imported by the MCP server.
