Implementation Reference
- src/tools/tab-tools.ts:15-17 (handler)MCP tool handler for 'list_tabs': calls listTabs() to get all tabs and returns them in a result object.
async () => { const tabs = await listTabs(); return handleResult(ok({ tabs })); - src/schemas.ts:10-10 (schema)Zod schema defining the input for list_tabs tool (empty object since no parameters required).
export const listTabsSchema = z.object({}); - src/tools/tab-tools.ts:11-19 (registration)Registers the 'list_tabs' tool with the MCP server, providing name, description, input schema, and handler function.
server.tool( 'list_tabs', 'List all open browser tabs with their IDs, URLs, and titles', listTabsSchema.shape, async () => { const tabs = await listTabs(); return handleResult(ok({ tabs })); } ); - src/tabs.ts:192-212 (helper)Helper function that implements the core logic for listing all tracked tabs: ensures browser init, fetches URL/title for each page, handles closed pages, indicates active tab.
export async function listTabs(): Promise<TabInfo[]> { await ensureInitialized(); const tabs: TabInfo[] = []; for (const [id, page] of state.tabs.entries()) { try { tabs.push({ id, url: page.url(), title: await page.title(), isActive: id === state.activeTabId, }); } catch { // Page may be closed, skip it state.tabs.delete(id); } } return tabs; }
