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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02881 | $0.02881 |
| Opus 5 | $0.01440 | $0.01440 |
| Sonnet 5 | $0.00576 | $0.00576 |
| Haiku 4.5 | $0.00288 | $0.00288 |
Grade A, and why
mcp-synology CLAUDE.md 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 8d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
mcp-synology is an MCP server for Synology NAS devices. It exposes Synology DSM API functionality as MCP tools that Claude can use. Modular, secure (2FA-ready), permission-tiered. Python 3.11+, async throughout, Apache 2.0 licensed.
Current status: v0.4.x — File Station (14 tools) + System monitoring (2 tools), CLI, integration tests.
Architecture
Layered design: core → modules → server/CLI.
- Core (
src/mcp_synology/core/): DSM API client (async httpx), auth manager (session lifecycle, 2FA, keyring), YAML+Pydantic config loader, shared response formatters, typed exception hierarchy - Modules (
src/mcp_synology/modules/): Feature-specific tool handlers. Each module declaresMODULE_INFOwith API requirements and tool metadata. File Station (14 tools: 7 READ + 7 WRITE), System (2 tools: get_system_info, get_resource_usage) - Server (
src/mcp_synology/server.py): FastMCP initialization, module loading, startup - CLI (
src/mcp_synology/cli/): click-based package withserve,setup,checksubcommands
Modules are domain-split: listing.py, search.py, metadata.py, operations.py, helpers.py — grouped by what they do, not permission tier.
Design Specs
Read the relevant spec before implementing. These are the source of truth for design decisions. If the code and a spec disagree, flag it — don't silently deviate.

Build & Development Commands
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.

mcp-synology CLAUDE.md is an instructions file published in the GitHub repository cmeans/mcp-synology (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 2,881 tokens to every session, about $0.0144 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
