This server demonstrates a security-focused educational design but suffers from severe definition quality issues. Tool duplication is rampant (check_device_compliance appears 4 times with inconsistent descriptions; apply_firmware_update appears 3 times). Parameter descriptions are minimal or absent, most tools have only a device_id with no explanation of format or constraints. Output schemas are not documented anywhere in the visible code. The server exposes 15 tool entries but only ~5 unique tools, creating confusion for LLM tool selection. Descriptions vary wildly in quality (some 10 chars, some 100+), violating consistency baselines. No error handling guidance, no pagination support, no output field documentation. While the security patterns (credential isolation, tool registry, triage gate) are conceptually sound, the tool interface itself is poorly specified for agent consumption.

• Deduplicate tools: merge 4 check_device_compliance variants into ONE canonical tool with a single, clear description (50 - 150 chars). Same for apply_firmware_update. Use the tool_registry pattern to control access, not tool duplication.
• Document output schemas for every tool. Example: 'Returns {device_id: string, firmware_version: string, compliance: "COMPLIANT"|"NON_COMPLIANT", last_seen: ISO8601}'. Include this in the tool definition or a separate schema reference.
• Add parameter descriptions with format/constraint hints. E.g., device_id: 'Device identifier in format D-XXXX (e.g., D-1042)'. target_version: 'Semantic version string (e.g., 2.4.0)'. Use enums for constrained values (compliance status, sensitivity levels).
• Implement error handling with recovery guidance. Return structured errors: {error: 'device_not_found', device_id: 'D-9999', suggestion: 'Try search_devices() with partial name'}. Categorize as retryable, user-fixable, or fatal.
• Add confirmation/dry-run for destructive tools. export_all_device_data and admin_reset_device should accept a dry_run=true parameter or require a separate confirm_export/confirm_reset call before executing. Prevent one-shot irreversible operations.
