Implementation Reference
- server.ts:53-71 (handler)The asynchronous handler function that executes the tool logic: fetches desktop image files and returns the count in a text response, with error handling.
async () => { try { const imageFiles = await getDesktopImageFiles(); return { content: [{ type: "text", text: `桌面上共有 ${imageFiles.length} 个图片文件。` }] }; } catch (error) { return { content: [{ type: "text", text: `获取图片数量时出错: ${error instanceof Error ? error.message : String(error)}` }], isError: true }; } } - server.ts:49-72 (registration)Registration of the 'count-desktop-images' tool with the MCP server, specifying name, description, empty input schema, and handler function.
server.tool( "count-desktop-images", "统计桌面上的图片文件数量", {}, async () => { try { const imageFiles = await getDesktopImageFiles(); return { content: [{ type: "text", text: `桌面上共有 ${imageFiles.length} 个图片文件。` }] }; } catch (error) { return { content: [{ type: "text", text: `获取图片数量时出错: ${error instanceof Error ? error.message : String(error)}` }], isError: true }; } } ); - server.ts:27-40 (helper)Core helper function that reads the desktop directory, filters image files using isImageFile, and returns their names.
const getDesktopImageFiles = async (): Promise<string[]> => { const desktopPath = getDesktopPath(); try { const files = await fs.readdir(desktopPath); const imagePaths = files.filter(file => { const filePath = path.join(desktopPath, file); return fs.statSync(filePath).isFile() && isImageFile(filePath); }); return imagePaths; } catch (error) { console.error(`Error reading desktop directory: ${error}`, ); return []; } }; - server.ts:19-23 (helper)Helper function to check if a file path corresponds to a supported image extension.
const isImageFile = (filePath: string): boolean => { const imageExtensions = ['.jpg', '.jpeg', '.png', '.gif', '.bmp', '.webp', '.tiff', '.svg']; const ext = path.extname(filePath).toLowerCase(); return imageExtensions.includes(ext); }; - server.ts:13-16 (helper)Helper function to resolve the user's desktop directory path.
const getDesktopPath = () => { const { homedir } = os.userInfo(); return path.join(homedir, 'Desktop'); };
