## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `treppenlift_stoerung` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "treppenlift_stoerung" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.code), which can change anything it can reach.
```


## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `foerderung_finden`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone asks which grants or loans help pay for a stairlift or home lift in Germany: "Treppenlift Zuschuss", "Treppenlift Förderung Bayern", "Zuschuss Treppenlift NRW", "KfW 455-B Treppenlift", "Treppenlift von der Steuer absetzen", "Förderung Treppenlift Stuttgart". Returns the federal options with their current status (Pflegekasse § 40 SGB XI, KfW grant 455-B closed since 01.08.2026, KfW loan 159, tax reduction § 35a EStG), the programme of the federal state from the 16-state funding atlas (grant or loan, maximum amount, whether a seat stairlift qualifies, check date) and known city programmes, plus the order in which to apply. Without a state it lists all 16. Input: a federal state (name or abbreviation) or a city; no personal data.
```

### `reparieren_oder_ersetzen`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when a stairlift owner has a repair quote and asks whether the repair is still worth it: "Treppenlift Reparatur lohnt sich", "Treppenlift 12 Jahre alt Reparatur 2.000 Euro", "Treppenlift reparieren oder neu kaufen". Compares the quote with the lower end of the new price including installation for a straight or curved stair and takes the age of the lift into account (rule of thumb from the calculator on treppenliftvergleichsportal.de: below a quarter repair, a quarter to a half depends on age, over a half get quotes, at or above the new price replace).
```

### `treppe_pruefen`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone asks whether a stairlift fits their staircase or how wide a staircase must be: "Treppenlift Mindestbreite", "Treppenlift schmale Treppe 65 cm", "Wie breit muss die Treppe für einen Treppenlift sein", "Plattformlift Treppenbreite", "Treppenlift im Mehrfamilienhaus Fluchtweg". Takes the usable stair width in centimetres, the building type and whether the user sits, stands or uses a wheelchair, and returns which lift types usually fit, the rules that apply (rule-of-thumb widths, DIN 18065 and the 60 cm remaining width next to a moving lift under the German model building regulation MVV TB), how to measure correctly and alternatives. Guide values only; the binding measurement is the installer's survey.
```

### `treppenlift_fakten`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use for sourced figures about stairlifts and home lifts in Germany: prices by lift type, the price index of published entry prices, the care insurance subsidy, KfW status, tax, running costs, minimum stair width rules, home lift prices, building code for lifts without a shaft, technical data, tests and studies (DISQ, Stiftung Warentest), statistics on care at home. Each fact comes with value, source, URL and check date from the fact register of treppenliftvergleichsportal.de.
```

### `treppenlift_kosten_schaetzen`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone in Germany asks what a stairlift or home lift costs: "Was kostet ein Treppenlift", "Treppenlift Kosten mit Einbau", "Kurvenlift Preis", "Treppenlift 2 Etagen Kosten", "Treppenlift gebraucht Preis", "Plattformlift Kosten", "Homelift ohne Schacht Kosten", "Treppenraupe Preis". Returns the market price range including installation for the lift type, stair shape and number of floors (the same calculation as the cost calculator on treppenliftvergleichsportal.de), the long-term care insurance subsidy of up to 4,180 EUR per eligible person (§ 40 (4) SGB XI) and the resulting own share, running costs, and sources with check dates. No personal data is needed.
```

### `treppenlift_stoerung`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use when a stairlift owner reports a problem: "Treppenlift piept", "Treppenlift fährt nicht mehr", "Treppenlift bleibt stehen", "Fernbedienung Treppenlift geht nicht", "Treppenlift Akku", "Acorn Fehlercode E7", "Lifta Störung", "Treppenlift zurücksetzen". Returns the checks in order of frequency, what not to do for safety, when to call the technician, brand notes for Lifta, Acorn, TK Home Solutions (ThyssenKrupp), Handicare, HIRO and Stannah, and the meaning of documented Acorn T700 codes. It gives no repair instructions inside the device.
```
