## 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 |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `how_to_book`

- 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
How to book a skip with Crestway Skip Hire: the phone number and hours, the next-day delivery cut-off, and what to have ready for the call (postcode, size, dates, drive or road, what’s going in). Give a postcode and a size for the guide price and whether a council road permit applies. Booking is by phone; this tool takes no personal details.
```

### `skip_prices`

- 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
Guide skip hire prices in England for a UK postcode (full, like "SN1 2AB", or just the district, like "SN1"): the price for each skip size from 2 yard mini to 12 yard maxi, ex VAT, with the local Crestway page for that town when there is one.
```

### `skip_sizes`

- 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
The standard UK skip sizes from 2 yard mini to 12 yard maxi: typical dimensions in metres, a rough black bin bag count, what each suits, where it usually goes and whether it takes heavy waste like soil and rubble.
```

### `town_skip_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
Verified local facts from a town’s Crestway skip hire page in England: guide prices, the council’s skip permit (fee, how long it takes, how to apply), the nearest recycling centres and what they take, council bulky and garden waste services, fly-tipping fines and figures, and common questions. Each fact has its source and the month it was checked.
```

## Only reads (1)

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

### `find_town`

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

Description, as the server wrote it:

```untrusted-server-text
Find English towns that have a Crestway skip hire page, by name or postcode district. Returns up to 5 matches with their county and page URL. Use the town name with town_skip_facts.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `skip-hire`:

    ],
    "ask": [

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.crestwayskiphire.co.uk/mcp: tools/list returned 5 tools to an anonymous client, including skip_prices (write), skip_sizes (write), town_skip_facts (write), how_to_book (write)
