F.4 Summary: Coverage Statistics

Category	Available in API	Covered by MCP (actions)	Gap
Queries	~30+	14	~16+ uncovered
Mutations	~50+	10 (start/stop Docker+VM, RClone CRUD)	~40+ uncovered
Subscriptions	~30+	0 (2 diagnostic only)	~30+ uncovered
Total	~110+	~24 unique API operations (76 actions across 10 tools)	~86+ uncovered

Current coverage: approximately 22% of available API operations (24 of ~110 unique GraphQL queries/mutations/subscriptions). Note: the MCP server exposes 76 actions, but many actions map to the same underlying API operation with different parameters.

G. Community Project Capabilities

G.1 unraid-management-agent (Go Plugin by Ruaan Deysel)

Capabilities this project offers that we do NOT:

Capability	Details	Our Status
SMART Disk Data	Detailed SMART attributes, health monitoring	NOT available via GraphQL API (Issue #1839)
Container Logs	Docker container log retrieval	Available via docker.logs query (we don't use it)
GPU Metrics	GPU utilization, temperature, VRAM	NOT available via GraphQL API
Process Monitoring	Active process list, resource usage	NOT available via GraphQL API
CPU Load Averages	Real-time 1/5/15 min load averages	Available via metrics query (we don't use it)
Prometheus Metrics	41 exportable metrics at /metrics	NOT applicable to MCP
MQTT Publishing	IoT event streaming	NOT applicable to MCP
Home Assistant Auto-Discovery	MQTT auto-discovery	NOT applicable to MCP
Disk Temperature History	Historical temp tracking	Limited via API
UPS Data	UPS status monitoring	Available via API (we don't use it)
Plugin Information	List installed plugins	NOT available via GraphQL API
Update Status	Check for OS/plugin updates	NOT available via GraphQL API
Mover Control	Invoke the mover tool	NOT available via GraphQL API (Issue #1873)
Disk Thresholds	Warning/critical temp settings	Partially available via ArrayDisk.warning/critical
54 MCP Tools	Full MCP tool suite	We have 10 tools (76 actions)
WebSocket Events	Real-time event stream	We have diagnostic-only subscriptions

G.2 PSUnraid (PowerShell Module)

Capability	Details	Our Status
Server Status	Comprehensive server overview	We have get_system_info()
Array Status	Array state and disk health	We have get_array_status()
Docker Start/Stop/Restart	Container lifecycle	We have start/stop only (no restart, no pause)
VM Start/Stop	VM lifecycle	We have full VM lifecycle
Notification Retrieval	Read notifications	We have list_notifications()
Restart Containers	Dedicated restart action	We do NOT have restart (would be stop+start)

G.3 unraid-ssh-mcp

Chose SSH over GraphQL API due to these gaps:

Missing from GraphQL API	Impact on Our Project
Container logs	Now available in API (docker.logs) -- we should add it
Detailed SMART data	Still missing from API (Issue #1839)
Real-time CPU load	Now available via metrics query -- we should add it
Process monitoring	Still missing from API
/proc and /sys access	Not applicable via API

G.4 Home Assistant Integrations

domalab/ha-unraid

Capability	Our Status
CPU usage, temperature, power consumption	NO - missing metrics tools
Memory utilization tracking	NO - missing metrics tools
Per-disk and per-share metrics	PARTIAL - have basic disk/share info
Docker container start/stop switches	YES
VM management controls	YES
UPS monitoring with energy dashboard	NO
Notification counts	YES
Dynamic entity creation	N/A

chris-mc1/unraid_api

Capability	Our Status

H. Known API Bugs and Limitations

H.1 Active Bugs (from GitHub Issues)

Issue	Title	Impact on MCP Implementation
#1837	GraphQL partial failures	CRITICAL: Entire queries fail when VMs/Docker unavailable. Must implement partial failure handling with separate try/catch per section.
#1842	Temperature inconsistency	SSD temps unavailable in disks query but accessible via array query. Use Array endpoint for temperature data.
#1840	Docker cache invalidation	Docker container data may be stale after external changes (docker CLI). Use skipCache: true parameter when available.
#1825	UPS false data	API returns hardcoded/phantom values when NO UPS is connected. Must validate UPS data before presenting to user.
#1861	VM PMSUSPENDED issues	Cannot unsuspend VMs in PMSUSPENDED state. Must handle this state explicitly and warn users.
#1859	Notification counting errors	Archive counts may include duplicates. Use recalculateOverview mutation to fix.
#1818	Network query failures	GraphQL may return empty lists for network data. Handle gracefully.
#1871	Container restart/update mutation	Single restart+update operation not yet in API. Must implement as separate stop+start.
#1873	Mover not invocable via API	No GraphQL mutation to trigger the mover. Cannot implement mover tools.
#1839	SMART disk data missing	Detailed SMART attributes not yet exposed via GraphQL. Major gap for disk health tools.
#1872	CLI list missing creation dates	Timestamp data unavailable in some CLI operations.

H.2 Schema/Type Issues

Issue	Description	Workaround
Int Overflow	Memory size fields and disk operation counters can overflow 32-bit Int. API uses Long/BigInt scalars but some fields remain problematic.	Parse values as strings, convert to Python int
NaN Values	Fields sysArraySlots, sysCacheSlots, cacheNumDevices, cacheSbNumDisks in vars query can return NaN.	Query only curated subset of vars fields (current approach)
Non-nullable Null	info.devices section has non-nullable fields that return null in practice.	Avoid querying info.devices entirely (current approach)
Memory Layout Size	Individual memory stick size values not returned by API.	Cannot calculate total memory from layout data
PrefixedID Format	IDs follow TypePrefix:uuid format. Clients must handle as opaque strings.	Already handled in current implementation

H.3 Infrastructure Limitations

Limitation	Description	Impact
Rate Limiting	100 requests per 10 seconds (@nestjs/throttler).	Must implement request queuing/backoff for bulk operations
EventEmitter Limit	Max 30 concurrent subscription listeners.	Limit simultaneous subscription tools
Disk Operation Timeouts	Disk queries require 90s+ read timeouts.	Already handled with custom timeout config
Docker Size Queries	sizeRootFs query is expensive.	Make it optional in list queries, only include in detail queries
Storage Polling Interval	SMART query overhead means storage data should poll at 5min minimum.	Rate-limit storage-related subscriptions
Cache TTL	cache-manager v7 expects TTL in milliseconds (not seconds).	Correct TTL units in any caching implementation
Schema Volatility	API schema is still evolving between versions.	Consider version-checking at startup, graceful degradation
Nchan Memory	WebSocket subscriptions can cause Nginx memory exhaustion (mitigated in 7.1.0+ but still possible).	Limit concurrent subscriptions, implement reconnection logic
SSL/TLS	Self-signed certificates require special handling for local IP access.	Already handled via UNRAID_VERIFY_SSL env var
Version Dependency	Full API requires Unraid 7.2+. Pre-7.2 needs Connect plugin.	Document minimum version requirements per tool
