SYNO.FileStation.Stat is absent from this NAS's API registry. SYNO.FileStation.List::getinfo returns identical data and is confirmed working. - tools/filestation.py: new get_info tool — accepts one or more comma-separated paths, calls getinfo with real_path/size/time/perm/ owner/type additional fields, returns a 9-column table - tests: 6 new tests covering single file, directory, multi-path, empty input, DSM error, and correct API method assertion - SPEC.md: remove SYNO.FileStation.Stat from API table, rewrite get_info tool section to reference getinfo, update list_dir note - CLAUDE.md: update Implemented Tools list Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# CLAUDE.md — mcp-synology-filestation
|
||
|
||
Development context for this project.
|
||
|
||
## Project
|
||
|
||
`mcp-synology-filestation` — MCP server exposing Synology FileStation as Claude tools.
|
||
Sibling project to `mcp-synology-container`.
|
||
|
||
## Infrastructure
|
||
|
||
- **NAS:** `https://dsm.gecheckt.de`
|
||
- **Config file:** `~/.config/mcp-synology-filestation/config.yaml`
|
||
- **Credentials:** OS keyring, service name `mcp-synology-filestation`
|
||
- **Gitea:** `https://gitea.gecheckt.de/marcus/mcp-synology-filestation`
|
||
- **Local code:** `D:\Dev\Projects\mcp-synology-filestation`
|
||
- **Runtime:** Python 3.12+, `uv`, MCP SDK, `httpx`, `keyring`, `click`, `rich`
|
||
|
||
## Deploy Workflow
|
||
|
||
1. Commit and push via Claude Code.
|
||
2. `uv tool install --reinstall git+https://gitea.gecheckt.de/marcus/mcp-synology-filestation.git`
|
||
3. Restart Claude Desktop.
|
||
|
||
## Toolchain
|
||
|
||
| Task | Command |
|
||
|------|---------|
|
||
| Format | `ruff format src/ tests/` |
|
||
| Lint | `ruff check src/ tests/` |
|
||
| Tests | `pytest` |
|
||
| Install dev | `uv sync --dev` |
|
||
| Run server | `uv run mcp-synology-filestation serve` |
|
||
| Setup | `uv run mcp-synology-filestation setup` |
|
||
|
||
## Code Standards
|
||
|
||
- **Type hints** on all public functions and methods.
|
||
- **Docstrings** (English) on all public modules, classes, and functions.
|
||
- **Async-first:** use `httpx.AsyncClient` throughout; never `requests`.
|
||
- **Formatter:** `ruff format` (line length 100).
|
||
- **Linter:** `ruff check` — fix all warnings before committing.
|
||
|
||
## Security Rules
|
||
|
||
- Never log or write credentials, session IDs, or passwords to disk or stderr.
|
||
- Never store passwords in the config YAML — OS keyring only.
|
||
- Mask sensitive query parameters (`_sid`, `passwd`) before logging request URLs.
|
||
|
||
## Destructive Operation Rules
|
||
|
||
- `delete`, `move` with `overwrite=True`, `copy` with `overwrite=True`, and `upload` with
|
||
`overwrite=True` are considered destructive.
|
||
- The `delete` tool MUST require `confirmed=True` to proceed. Without it, return a preview
|
||
message that describes exactly what would be deleted — never silently proceed.
|
||
- For overwrite scenarios in `move`/`copy`/`upload`, include a warning in the tool description
|
||
and default `overwrite` to `False`.
|
||
|
||
## Error Handling Rules
|
||
|
||
- DSM error codes must be mapped to human-readable messages. See SPEC.md for the full map.
|
||
- Never surface raw Python stack traces in tool return values.
|
||
- Session expiry (codes 106, 107, 119): transparent single retry with re-login.
|
||
- Network errors: return "Cannot reach NAS at {host} — check connectivity."
|
||
- Auth failures (400–403): return message + "Run `mcp-synology-filestation setup` to
|
||
reconfigure credentials."
|
||
|
||
## Tool Return Format
|
||
|
||
- All tools return `str`.
|
||
- Use `rich.table.Table` (rendered to string) for tabular data.
|
||
- Include item counts and pagination hints where relevant.
|
||
- Error messages are prefixed with `Error:` for easy recognition by Claude.
