Implementation Reference
- src/index.ts:143-145 (schema)Input schema definition for the get_file_info tool using Zod.const GetFileInfoArgsSchema = z.object({ path: z.string().describe('Path to the file or directory to get information about'), })
- src/index.ts:316-324 (registration)Tool registration in the list_tools response, including name, description, and input schema reference.{ 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:682-705 (handler)Main handler logic in the tool call switch statement: validates input, checks path, gets stats using getFileStats, formats and returns file info.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:170-181 (helper)Helper function that retrieves detailed file statistics using fs.stat and formats into FileInfo object.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), } }
