Unraid MCP Skill

Mode Detection

MCP mode (preferred): Use when mcp__unraid-mcp__unraid tool is available.

HTTP fallback: Use when MCP tools are unavailable. Credentials are in Bash subprocesses as $CLAUDE_PLUGIN_OPTION_UNRAID_API_URL and $CLAUDE_PLUGIN_OPTION_UNRAID_API_KEY. Do NOT attempt ${user_config.unraid_api_key} in curl — sensitive values only work as $CLAUDE_PLUGIN_OPTION_* in Bash subprocesses.

MCP URL: ${user_config.unraid_mcp_url}

---

Use the single unraid MCP tool with action (domain) + subaction (operation) for all Unraid operations.

Setup

First time? Run setup to configure credentials:

unraid(action="health", subaction="setup")

Credentials are stored at ~/.unraid-mcp/.env. Re-run setup any time to update or verify.

Calling Convention

unraid(action="<domain>", subaction="<operation>", [additional params])

Examples:

unraid(action="system",  subaction="overview")
unraid(action="docker",  subaction="list")
unraid(action="health",  subaction="check")
unraid(action="array",   subaction="parity_status")
unraid(action="disk",    subaction="disks")
unraid(action="vm",      subaction="list")
unraid(action="notification", subaction="overview")
unraid(action="live",    subaction="cpu")

Notes

• Rate limit: 100 requests / 10 seconds
• Log path validation: Only /var/log/, /boot/logs/, /mnt/ prefixes accepted
• Container logs: Docker container stdout/stderr are NOT accessible via API — use SSH + docker logs
• arraySubscription: Known Unraid API bug — live/array_state may show "connecting" indefinitely
• Event-driven subs (notifications_overview, owner, server_status, ups_status): Only populate cache on first real server event

---

HTTP Fallback Mode

When MCP tools are unavailable, use direct GraphQL queries via curl. Credentials are available as $CLAUDE_PLUGIN_OPTION_* environment variables in Bash subprocesses.

# System overview
curl -s "$CLAUDE_PLUGIN_OPTION_UNRAID_API_URL" \
  -H "x-api-key: $CLAUDE_PLUGIN_OPTION_UNRAID_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ info { os { hostname uptime } } }"}'

# List Docker containers
curl -s "$CLAUDE_PLUGIN_OPTION_UNRAID_API_URL" \
  -H "x-api-key: $CLAUDE_PLUGIN_OPTION_UNRAID_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ docker { containers { names state status } } }"}'

# Array status
curl -s "$CLAUDE_PLUGIN_OPTION_UNRAID_API_URL" \
  -H "x-api-key: $CLAUDE_PLUGIN_OPTION_UNRAID_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"{ array { state capacity { kilobytes { free used total } } disks { name status temp } } }"}'
