Server has 23 tools with complete input schemas and descriptions, but quality is inconsistent. Naming follows verb_noun convention (system_info, file_read, nginx_reload). Descriptions are present but often generic (e.g., 'Read Nginx configuration file' lacks context on when to use it vs alternatives). Many parameters lack descriptions: disk_analysis 'depth' has no description; command_exec 'cwd' lacks guidance on path resolution. Output schemas are not documented anywhere, LLMs cannot predict response structure. Error handling is minimal: no recovery guidance, no categorization of retryable vs fatal errors. Security concerns: command_exec accepts arbitrary commands with only a whitelist check (not visible in source), and file operations lack path traversal validation details. Confirmation pattern is implemented but not integrated into tool definitions consistently.

• Document output schemas for all tools. Include field names, types, and examples. For paginated results (log_read, file_search), specify limit, offset, total_count, and next_cursor fields.
• Add descriptions to all parameters. For numeric params (depth, lines, limit, offset), specify min/max ranges. For categorical params (level, plugin), use enums instead of free-form strings.
• Implement structured error responses with recovery guidance. Example: 'File not found at /path/to/file. Check file_list() to see available files in the directory.'
• Validate and sanitize all user inputs. For file operations, enforce path boundaries (no ../ traversal). For command_exec, document the whitelist and reject unlisted commands with a clear error.
• Integrate confirmation pattern into tool definitions. Mark requiresConfirmation in the ToolDefinition interface and document which operations require user approval in their descriptions.
