## 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 (1)

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

### `check_offers`

- 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
Pocketly’s quick check: which offers fit a situation and the order that pays most, with dates and what is left after costs. The same planner and answer as pocketly.co.uk/check. Amounts in pounds. Nothing is stored.
```

## Only reads (4)

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

### `get_offer`

- The name "get_offer" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One offer by its id (from list_offers or its pocketly.co.uk/offers/<id> address).
```

### `list_changes`

- The name "list_changes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every offer edition Pocketly has published, newest first.
```

### `list_offers`

- The name "list_offers" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every live UK current-account switching offer Pocketly holds: what it pays and what Pocketly counts, each condition with the bank’s own words, who can’t get it, and when it was last checked.
```

### `list_savings_and_cashback`

- The name "list_savings_and_cashback" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Savers and cashback from banks’ own pages, never counted in a plan: each with the most it pays by its own terms (or per £1,000 for easy-access savers), in the bank’s words.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `offers`:

```json
{
  "permissions": {
    "allow": [
      "mcp__offers__list_offers",
      "mcp__offers__get_offer",
      "mcp__offers__list_savings_and_cashback",
      "mcp__offers__list_changes"
    ],
    "ask": [
      "mcp__offers__check_offers"
    ],
    "deny": []
  }
}
```

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.pocketly.co.uk/mcp: tools/list returned 5 tools to an anonymous client, including check_offers (write)
