export async function updateItem( projectPath: string, itemId: number, updates: Partial<Item> ): Promise<Item> { const items = await getItems(projectPath); const itemIndex = items.findIndex(item => item && item.id === itemId); if (itemIndex === -1) { throw new Error(`Item with ID ${itemId} not found`); } items[itemIndex] = { ...items[itemIndex], ...updates }; const itemsPath = getDataPath(projectPath, 'Items.json'); await writeJsonFile(itemsPath, items); return items[itemIndex]; } - src/index.ts:341-351 (registration)Registration of the `update_item` tool definition in the MCP server.
