Implementation Reference
- src/index.ts:682-705 (handler)The handler implementation for the 'get_file_info' tool. It parses input arguments using the schema, validates the path against allowed directories, retrieves file stats using the getFileStats helper, and returns formatted metadata as text.case 'get_file_info': { const parsed = GetFileInfoArgsSchema.safeParse(a) if (!parsed.success) { throw new FileSystemError(`Invalid arguments for ${name}`, 'INVALID_ARGS', undefined, { errors: parsed.error.format(), }) } const validPath = await validatePath(parsed.data.path, config) const info = await getFileStats(validPath) await logger.debug(`Retrieved file info: ${validPath}`) endMetric() return { content: [ { type: 'text', text: Object.entries(info) .map(([key, value]) => `${key}: ${value}`) .join('\n'), }, ], } }
- src/index.ts:143-145 (schema)Zod schema defining the input parameters for the get_file_info tool, requiring a 'path' string.const GetFileInfoArgsSchema = z.object({ path: z.string().describe('Path to the file or directory to get information about'), })
- src/index.ts:317-324 (registration)Registration of the get_file_info tool in the list_tools response, including name, description, and input schema.name: 'get_file_info', description: 'Retrieve detailed metadata about a file or directory. Returns comprehensive ' + 'information including size, creation time, last modified time, permissions, ' + 'and type. This tool is perfect for understanding file characteristics ' + 'without reading the actual content. Only works within allowed directories.', inputSchema: zodToJsonSchema(GetFileInfoArgsSchema) as ToolInput, },
- src/index.ts:170-181 (helper)Helper function that fetches and formats detailed file system stats for a given path, returning size, timestamps, type flags, and permissions.async function getFileStats(filePath: string): Promise<FileInfo> { const stats = await fs.stat(filePath) return { size: stats.size, created: stats.birthtime, modified: stats.mtime, accessed: stats.atime, isDirectory: stats.isDirectory(), isFile: stats.isFile(), permissions: stats.mode.toString(8).slice(-3), } }
