Strong foundation with 15 well-named tools following verb_noun convention (list_*, get_*). All tools have descriptions (avg ~180 chars, within 10-1024 baseline). Input schemas are present with type declarations and parameter descriptions. However, output schemas are undocumented, responses are raw API JSON without field documentation. Error handling is basic (generic error messages without recovery guidance). No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all being READ-ONLY. Parameter validation is solid (numeric ID checks, safe param checks) but not exposed in descriptions. Missing: enum constraints for status/level fields, explicit pagination guidance in descriptions, and structured output documentation.

• Add readOnlyHint annotation to all 15 tools via mcp.WithReadOnly() to signal they are safe to retry and have no side effects.
• Document output schemas for each tool. Example for imc_list_devices: 'Returns {devices: [{deviceId: string, label: string, ip: string, status: string, model: string, mac: string}], total: number}'.
• Replace generic error messages with actionable recovery guidance. Example: 'Device not found (deviceId=999). Call imc_list_devices to find valid device IDs.' Use mcp.NewToolResultError() with context.
• Add enum constraints to status/level parameters. Example: alarmLevel should declare enum: ['1', '2', '3', '4'] with descriptions (1=Critical, 2=Major, 3=Minor, 4=Info).
• Enhance pagination descriptions. State: 'Returns up to {size} records (default 10, max 100). Use start+size for iteration. Response includes total count for planning.' Add explicit limits to tool descriptions.
