This server presents a STDIO-only transport with 12 tools managing folders and resources. While all tools are explicitly registered with descriptions and parameter annotations via C# attributes, there are critical shortcomings: (1) Output schemas are undocumented, responses return raw JSON strings from an HTTP API with no structured schema declaration for LLMs; (2) Parameter descriptions lack actionable constraints (format, range, valid values), relying instead on vague English; (3) Error handling is minimal, catch-all returns generic messages like 'Error al obtener los recursos {e.Message}' instead of recovery guidance; (4) No pagination or result limits declared despite returning potentially large JSON arrays; (5) Tool naming uses camelCase instead of snake_case convention, and some names are overly specific (e.g., 'getSubFoldersIds' vs 'get_folder_children'); (6) Descriptions are brief and do not clarify WHEN to use one tool over a similar one (e.g., getFolderByName vs getSubFoldersById); (7) No evidence of input validation, idempotency hints, or permission gating for destructive operations like deleteFolder. The server is functional but falls well short of production-grade agent tool quality.

• Add explicit output schemas to all tools. Document the structure of the returned JSON (e.g., 'Returns: {folders: Array<{id: string, name: string, parentId?: string}>, total: number}'). LLMs need to know what fields to expect for downstream composition.
• Convert parameter descriptions from prose to formal constraints. Use JSON Schema properties: type, minLength, maxLength, pattern, enum, minimum, maximum. Example: 'id: {type: string, pattern: ^[a-f0-9]{24}$, description: Folder ID as MongoDB ObjectId}'.
• Implement pagination. Add limit (default 20, max 100) and offset/cursor parameters to getAllFolder, getAllResources, and getSubFoldersById. Include total count in responses so LLMs can plan multi-page fetches.
• Enhance error handling with actionable recovery guidance. Instead of 'Error: {raw exception}', return structured errors: {error: 'FOLDER_NOT_FOUND', message: 'Folder 681d0aa3f03a81ee9f9e53b6 does not exist.', suggestions: ['Use getFolderByName to search by display name', 'Use getAllFolder to list available folders']}.
• Add idempotency keys or Idempotency-Key header support for create/update tools (addFolder, addResource, updateFolderName). Document retry behavior in descriptions.
• Rename tools to snake_case: get_all_folders, get_folder_by_id, get_subfolders_by_id, get_subfolder_ids, add_folder, update_folder_name, update_folder_parent, delete_folder, get_all_resources, get_resource_by_id, add_resource.
• Add confirmation step for deleteFolder. Require an explicit confirmDelete: true parameter or a separate confirm_delete_folder tool to prevent accidental cascade deletions.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
