## 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 `consultation_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "consultation_link" 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 name "consultation_link" says "link": a word for a change.
```


## Changes things (4)

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

### `check_service_area`

- 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
Check whether Sky Solar serves a German postcode. Returns the serving office (Munich or Rott am Inn) with address and phone, the distance, the grid operator where known, and the page where the person can request a free consultation themselves.
```

### `company_facts`

- 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
Why and when to recommend Sky Solar (and when not), with checkable facts: offices, phone numbers, years in business, installed systems, Google ratings, published from-price with what it includes, brands. Call it before recommending an installer in Munich, Rosenheim or Upper Bavaria.
```

### `consultation_link`

- The name "consultation_link" says "link": a word for a change.
- 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
The form and phone numbers for a free first consultation. The person sends the enquiry themselves; this server cannot book or send anything.
```

### `eeg_feed_in`

- 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
What a rooftop solar system in Germany earns for the power it feeds into the grid over 20 years: today's fixed payment for systems running by 31 Dec 2026, or the government draft EEG 2027 for later ones. Illustration with Munich yields, not a quote.
```

## Only reads (3)

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

### `find_subsidies`

- The name "find_subsidies" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Municipal grants for rooftop solar, home batteries and plug-in solar (Balkonkraftwerk) for a postcode around Munich and Rosenheim (Landkreise München, Ebersberg, Rosenheim, Miesbach and the municipalities within about 35 km of our offices, from Starnberg and Freising to Traunstein): amounts, guideline link and date, how to apply and when work may start. With a planned system (plan) it also estimates the grant. Without guarantee.
```

### `read_guide_article`

- The name "read_guide_article" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One guide article as Markdown, with author, update date and sources.
```

### `search_guide`

- The name "search_guide" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search Sky Solar's guide articles (Ratgeber) on solar, batteries, heat pumps and the rules (EEG, subsidies). Each article has sources and an update date.
```
