synology-nas

synology-nas is a skill for Claude Code, Codex from atom2ueki/mcp-server-synology. It costs 212 tokens per session (2,151 once invoked), scanned A, original, MIT.

A guide for managing a Synology NAS, a network storage device, through its connected tools. It covers files, folders, downloads, storage health, disks, RAID or SHR volumes, UPS devices, and system usage.

In plain words
What is it for?
Use it to search or manage NAS files, create files, run downloads, inspect disks and volumes, check backups or power protection, and monitor system resources.
Why use it?
It provides a consistent way to discover the available NAS and check the login state before taking action. It also helps choose broad summaries for checkups or focused tools for specific details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

synology-nas scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Synology NAS

This skill teaches you how to use the mcp-server-synology MCP effectively. The MCP exposes ~80 tools across seven domains; the trick is picking the right tool, targeting the right NAS, and not exploding a single user request into a dozen redundant calls.

Mental model

Three things shape almost every interaction:

  1. Targeting — most setups have one NAS and you can omit the target argument. Multi-NAS setups require a nas_name (or base_url) on every tool call. Don't guess; discover first.
  2. State — auth is session-based and usually auto-managed. You almost never need to call synology_login yourself. Check status first; only log in if status says you must.
  3. Aggregation — several individual tools have a *_summary equivalent. When the user wants a "checkup" or "overview," reach for the aggregate. When they want a specific number, use the targeted tool.

Once those three are settled, the rest is picking the right domain.

Always start here

Before any operation, run discovery — it's two cheap calls and answers "which NAS?" and "am I logged in?":

  1. synology_list_nas — lists configured NAS units with names, URLs, connection status.
  2. synology_status — shows which sessions are active.

If the user mentions a NAS by name (e.g. "the backup NAS", "nas2"), match it to a nas_name from synology_list_nas. If only one NAS is configured, you can omit nas_name on subsequent calls. If multiple are configured and the user is ambiguous, ask which one — don't pick.

Tool call shape

Every operational tool accepts an optional target argument:

  • nas_name (preferred) — the identifier from settings.json, e.g. "nas1".
  • base_url — fallback when the NAS isn't in settings.json.

Pass at most one. Omit both only when there's a single NAS configured.

Path arguments must start with /. User-facing data lives under /volume1/ (or /volume2/, etc., for additional volumes). The root / lists shares; /homes, /photo, /video etc. are share-level mount points underneath. Don't invent paths — list the parent first if unsure.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
