# CLAUDE.md Arbeitsanweisung für mcp-synology-container
## Deine Aufgabe
Implementiere das Projekt `mcp-synology-container` vollständig gemäß `SPEC.md`.
Lies `SPEC.md` jetzt vollständig, bevor du anfängst.
---
## Referenzmaterial
Im Ordner `reference/` findest du zwei Referenzprojekte. Nutze sie aktiv:
### `reference/cmeans/`
Geklontes Repo von `cmeans/mcp-synology` (GitHub).
Übernimm daraus die Implementierungsmuster für:
- Auth-Flow und 2FA-Device-Token-Flow (`auth.py`)
- OS-Keyring-Integration (`keyring` library)
- CLI-Struktur mit `click` (`cli.py`)
- Config laden/speichern mit YAML (`config.py`)
- Credential-Auflösungsreihenfolge (env vars → config → keyring)
- `setup`-Wizard mit `rich` für formatierte Ausgabe
- Generierung des Claude-Desktop-Config-Snippets
Passe alle übernommenen Muster an unseren Use-Case an.
Kopiere keinen Code blind verstehe ihn und adaptiere ihn.
### `reference/n4s4/docker_api.py`
Einzelne Datei aus `N4S4/synology-api` (GitHub).
Nutze sie als Referenz für die konkreten DSM API-Calls:
- Wie `SYNO.Docker.Project` aufgerufen wird (list, start, stop)
- Wie `SYNO.Docker.Container` aufgerufen wird (list, logs, exec)
- Wie `SYNO.Docker.Image` aufgerufen wird (list)
- Welche Parameter und Response-Strukturen die APIs erwarten
Implementiere **keinen** eigenen Wrapper um `synology-api`
baue einen eigenen schlanken HTTP-Client in `dsm_client.py` mit `httpx`.
---
## Reihenfolge der Implementierung
Arbeite in dieser Reihenfolge. Schließe jeden Schritt vollständig ab bevor du weitermachst:
1. **Projektstruktur anlegen** alle Ordner und leere `__init__.py`-Dateien, `pyproject.toml`
2. **`config.py`** Config laden, speichern, validieren
3. **`auth.py`** Keyring-Integration, Login gegen DSM API, 2FA-Device-Token-Flow
4. **`dsm_client.py`** HTTP-Client mit Session-Management, Auto-Re-Login
5. **`cli.py`** `setup`, `check`, `serve` Befehle
6. **`modules/projects.py`** SYNO.Docker.Project Tools
7. **`modules/containers.py`** SYNO.Docker.Container Tools
8. **`modules/compose.py`** Compose-Datei lesen/schreiben via FileStation API
9. **`modules/images.py`** SYNO.Docker.Image Tools
10. **Tests** für jeden Schritt
11. **`README.md`** Installationsanleitung und Tool-Übersicht
12. **`docs/setup.md`** und **`docs/tools.md`**
---
## Wichtige Implementierungsregeln
- **Confirmation vor destruktiven Operationen:** `stop_project`, `redeploy_project`,
`exec_in_container`, `update_image_tag`, `update_env_var`, `update_compose` müssen
eine Bestätigung vom Nutzer einholen bevor sie ausgeführt werden. Nutze dafür den
MCP-eigenen `confirm`-Mechanismus.
- **Nach Compose-Änderungen:** Immer automatisch `redeploy_project` vorschlagen.
- **Fehlerbehandlung:** Alle DSM API-Fehler sauber abfangen und als verständliche
Fehlermeldung zurückgeben. Keine Python-Stacktraces zum Nutzer.
- **Keine Secrets in Logs:** Passwörter, Tokens und Session-IDs niemals in
stderr-Ausgaben schreiben.
- **HTTPS:** `verify_ssl: true` ist der Standard. Nur auf expliziten Wunsch deaktivierbar.
- **Compose-Pfade:** Beide Varianten erkennen `docker-compose.yml` und `compose.yml`.
- **Type Hints:** Konsequent in allen Funktionen verwenden.
- **Docstrings:** Für alle öffentlichen Funktionen und Klassen.
---
## Projekt-Konventionen
- Sprache: Python 3.12+
- Formatter: `ruff format`
- Linter: `ruff check`
- Tests: `pytest`
- Alle Texte (Docstrings, Kommentare, README): Englisch

# mcp-synology-container
An MCP (Model Context Protocol) server for managing Docker projects on a Synology NAS via Container Manager. Enables Claude Desktop to list, start, stop, redeploy, and modify Docker Compose projects directly.
## Features
- **Project management**: list, start, stop, redeploy Container Manager projects
- **Container inspection**: list containers, view status and resource usage, fetch logs
- **Compose file editing**: read, modify image tags, update env vars, or replace compose files entirely
- **Image update checks**: see which images have updates available
- **2FA support**: device token flow for Synology accounts with OTP enabled
- **OS keyring integration**: credentials stored securely, never in config files
- **Confirmation required** for all destructive operations (stop, redeploy, exec, compose writes)
## Requirements
- Python 3.12+
- Synology NAS with DSM 7.x and Container Manager installed
- `pip` or `uv` for installation
## Installation
```bash
pip install mcp-synology-container
```
Or with `uv`:
```bash
uv tool install mcp-synology-container
```
## Setup
Run the interactive setup wizard:
```bash
mcp-synology-container setup
```
The wizard will:
1. Ask for your NAS hostname/IP, port, and HTTPS settings
2. Ask for your DSM username and password
3. Handle 2FA if enabled (stores device token in OS keyring)
4. Save the config to `~/.config/mcp-synology-container/config.yaml`
5. Print the Claude Desktop configuration snippet
### Claude Desktop configuration
Add the snippet to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"synology-container": {
"command": "mcp-synology-container",
"args": ["serve"]
}
}
}
```
## CLI Commands
### `mcp-synology-container setup`
Interactive setup: configure connection and store credentials.
```bash
mcp-synology-container setup
mcp-synology-container setup --verbose
```
### `mcp-synology-container check`
Test the connection and verify all required APIs are available.
```bash
mcp-synology-container check
mcp-synology-container check --config /path/to/config.yaml
```
Exit code 0 = OK, 1 = error.
### `mcp-synology-container serve`
Start the MCP server (used by Claude Desktop).
```bash
mcp-synology-container serve
mcp-synology-container serve --config /path/to/config.yaml
```
## Configuration
Config file: `~/.config/mcp-synology-container/config.yaml`
```yaml
schema_version: 1

## Konfigurationsdatei
Pfad: `~/.config/mcp-synology-container/config.yaml`
```yaml
schema_version: 1
alias: HomeNAS # optionaler Anzeigename in Claude Desktop
connection:
host: dsm.gecheckt.de
port: 443
https: true
verify_ssl: true
compose_base_path: /volume1/docker # Basis-Pfad für alle Compose-Projekte auf der NAS
```
Credentials (Host, Username, Password, optional Device-Token für 2FA) werden
**nicht** in der Config-Datei gespeichert, sondern ausschließlich im OS-Keyring.
**Credential-Auflösungsreihenfolge:**
1. Umgebungsvariablen (`SYNOLOGY_HOST`, `SYNOLOGY_USERNAME`, `SYNOLOGY_PASSWORD`)
2. Config-Datei (nur nicht-sensitive Werte)
3. OS-Keyring (Credentials)
---
## CLI-Befehle
### `mcp-synology-container setup`
Interaktiver Setup-Wizard:
1. Fragt Host, Port, HTTPS, Benutzername, Passwort ab
2. Prüft ob 2FA aktiv ist wenn ja: OTP abfragen, Device-Token speichern
3. Speichert Credentials im OS-Keyring
4. Schreibt `config.yaml`
5. Gibt fertiges Claude-Desktop-Config-Snippet aus:
```json
{
"mcpServers": {
"synology-container": {
"command": "mcp-synology-container",
"args": ["serve"]
}
}
}
```
### `mcp-synology-container check`
- Lädt Config und Credentials
- Stellt Testverbindung zur DSM API her
- Gibt Verbindungsstatus, DSM-Version und verfügbare APIs aus
- Exit-Code 0 = OK, 1 = Fehler
### `mcp-synology-container serve`
- Startet den MCP-Server im stdio-Modus
- Registriert alle Tools
- Läuft bis SIGTERM/SIGINT
---

# Setup Guide
## Prerequisites
- Python 3.12 or higher
- A Synology NAS running DSM 7.x with **Container Manager** installed
- Network access to the NAS from the machine running Claude Desktop
## Installation
### With pip
```bash
pip install mcp-synology-container
```
### With uv
```bash
uv tool install mcp-synology-container
```
Verify installation:
```bash
mcp-synology-container --help
```
---
## Running Setup
```bash
mcp-synology-container setup
```
The wizard will prompt you for:
| Prompt | Example | Notes |
|---|---|---|
| NAS hostname or IP | `192.168.1.100` or `nas.example.com` | |
| Use HTTPS? | `y` | Recommended |
| Port | `443` | Default for HTTPS |
| Verify SSL certificate? | `y` | Disable only for self-signed certs |
| Base path for compose projects | `/volume1/docker` | Where your compose projects live on the NAS |
| Alias | `HomeNAS` | Optional friendly name |
| DSM username | `admin` | DSM account with Container Manager access |
| DSM password | | Hidden input |
### If 2FA is enabled
If your DSM account has OTP enabled, the setup wizard will ask for your OTP code and store a device token in the OS keyring. Subsequent logins will use the device token — no OTP prompts during normal operation.
If your device token is revoked, run `setup` again to re-bootstrap.
---
## Verifying the Connection
```bash
mcp-synology-container check
```
Example output:
```
Host: nas.example.com:443
HTTPS: True
Verify SSL: True
Compose: /volume1/docker
Credentials: found (user=admin, 2FA=yes)
API info: fetched successfully
Login: successful
Required APIs:
SYNO.Docker.Container: v1-v1 ✓
SYNO.Docker.Container.Log: v1-v1 ✓
SYNO.Docker.Image: v1-v1 ✓
SYNO.Docker.Project: v1-v1 ✓
SYNO.FileStation.Download: v1-v2 ✓
SYNO.FileStation.Upload: v1-v3 ✓
All checks passed.
```
Exit code 0 means everything is working. Exit code 1 means a problem was detected.
---
## Configuring Claude Desktop
After running `setup`, the wizard prints a configuration snippet. Add it to your Claude Desktop config file:
**macOS/Linux**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
```json
{
"mcpServers": {
"synology-container": {
"command": "mcp-synology-container",
"args": ["serve"]
}
}
}
```
Restart Claude Desktop after editing the config.
---
## Config File Location
The config is saved to:
```
~/.config/mcp-synology-container/config.yaml
```
Example config:
```yaml
# Generated by mcp-synology-container setup
schema_version: 1
alias: HomeNAS
connection:
host: nas.example.com
port: 443
https: true
verify_ssl: true
compose_base_path: /volume1/docker
```
**Credentials are NOT stored in this file.** They are stored in the OS keyring.
---
## Alternative: Environment Variables
If you prefer not to use the keyring (e.g. in Docker or CI environments), set these environment variables:
```bash
export SYNOLOGY_HOST=192.168.1.100
export SYNOLOGY_USERNAME=admin
export SYNOLOGY_PASSWORD=yourpassword
```
Environment variables take priority over the keyring.
You can also specify the config path:
```bash
export MCP_SYNOLOGY_CONTAINER_CONFIG=/path/to/config.yaml
```
Or pass it explicitly:
```bash
mcp-synology-container serve --config /path/to/config.yaml
```
---
## DSM User Permissions
The DSM account used by the MCP server needs:
- Access to **Container Manager** (DSM > Control Panel > User > Applications)
- **Read/Write** access to the shared folder where compose projects are stored
For read-only use (listing projects and viewing logs), read access is sufficient.
---
## Troubleshooting
**Connection refused / timeout**
- Check NAS hostname and port
- Verify the NAS is reachable from your machine
- Try `mcp-synology-container check --verbose`
**Login failed**
- Run `mcp-synology-container setup` to re-enter credentials
- Check DSM > Control Panel > Security > Auto Block for IP blocks
**2FA fails**
- Run `mcp-synology-container setup` again to get a fresh device token
- If your account has app-specific 2FA enforcement, ensure the device token was saved
**Container Manager APIs not found**
- Ensure Container Manager is installed and running in DSM Package Center
- The package may appear as "Docker" in older DSM versions
**SSL certificate errors**
- For self-signed certificates: run `setup` again and answer `n` to "Verify SSL certificate?"
- Alternatively set `verify_ssl: false` in your config file

nginx:1.24 (50 MiB) ← UPDATE AVAILABLE
Up to date (1):
postgres:15 (80 MiB)
```
---
## Confirmation Pattern
Tools that modify state require confirmation to prevent accidents. The pattern is:
1. Call the tool without `confirmed`:
```
stop_project(project_name="myapp")
```
Returns a description of what will happen.
2. Call again with `confirmed=True`:
```
stop_project(project_name="myapp", confirmed=True)
```
Executes the operation.
This applies to: `stop_project`, `redeploy_project`, `exec_in_container`, `update_image_tag`, `update_env_var`, `update_compose`.
