## 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

No check matched anything in these tool definitions.


## Changes things (3)

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

### `decision_checklist`

- 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 this when preparing questions for an installer, a lender, or both. Do not use this to collect the answers, a TFN, an SSN, a Medicare number, bank details, or a card number.
```

### `estimate_bill_savings`

- 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 this when you have daily kWh, tariffs, and a system size and want classroom energy-bill arithmetic. Do not use this as a quote, a savings guarantee, or a credit offer. Do not send an account or identity number.
```

### `product_faq`

- 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 this when the question is about SparkReady or how household solar and battery loans usually work, and the public FAQ may cover it. Do not use this to invent an answer, assess an application, or request a TFN, SSN, Medicare number, bank account, or card.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `compare_scenarios`

- The name "compare_scenarios" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when comparing cash, a loan, and adding a battery later with numbers the caller already has. Do not use this to offer a rate or say they should borrow. A missing rate uses a labelled 7% teaching default, not a lender rate.
```

### `explain_battery`

- The name "explain_battery" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when explaining what a home battery stores and why backup is a separate feature. Do not use this to recommend a product or promise bill savings.
```

### `explain_hesl`

- The name "explain_hesl" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when explaining the NSW Home Energy Saver program: the loan cap, published income thresholds, what it can fund, and who delivers it. Do not use this to decide if a person is eligible or approved. Send them to energy.nsw.gov.au.
```

### `explain_insulation`

- The name "explain_insulation" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when explaining ceiling insulation and draught-proofing, including the NSW loan list. Do not use this to specify a product or print a savings figure.
```

### `explain_loan_basics`

- The name "explain_loan_basics" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone wants a short explanation of how an Australian household solar or battery loan fits together. Do not use this to say they are eligible or approved, or to quote a personal rate. Do not collect a TFN, SSN, Medicare number, bank details, or card number.
```

### `explain_loan_options`

- The name "explain_loan_options" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when comparing cash, a personal or green loan, installer finance, a home-loan top-up, and the NSW Home Energy Saver Loan. Do not use this to rank a cheapest option or publish a rate as an offer.
```

### `explain_solar`

- The name "explain_solar" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when explaining how rooftop solar meets a household bill: imports, exports, and STCs. Do not use this as a quote or a site assessment.
```
