## Exfil surface

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

| 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. | `mcp__pagewatch__read_page` `mcp__pagewatch__screenshot` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__pagewatch__pdf` `mcp__pagewatch__read_page` `mcp__pagewatch__screenshot` |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `balance`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check the remaining free credits on your pagewatch key, plus the per-call
        prices and, if the key is not switched on yet, the free activation link to
        give your human. Pass api_key if you did not configure an Authorization header.

        api_key: an existing pagewatch bearer token, optional.
        
```

### `pdf`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Render a web page (by url) or raw html into a pdf and return it as base64
        pdf data. Provide exactly one of url or html. Respects robots.txt for url
        input. Pass api_key if you have a pagewatch key, otherwise a free trial key is
        created for you and returned.

        url: the page to convert, optional.
        html: raw html to convert, optional (provide url or html, not both).
        api_key: an existing pagewatch bearer token, optional.
        paper: A4, Letter, Legal or A3.
        landscape: landscape orientation.
        
```

### `register`

- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a pagewatch api key for yourself. Free, no signup and no human form.
        Returns a bearer token that starts with a small free trial so your first
        read_page, screenshot or pdf works right away. When the trial runs out, hand
        the returned verification_uri_complete to your human, who confirms one email
        to unlock 200 more free credits (still free, nothing to pay). Reuse the token
        by passing it as api_key, or set it as Authorization: Bearer <token> on this
        server. Nothing is ever charged: pagewatch has no payment processor connected.

        label: a short name for this key, optional.
        purpose: why you want web access, shown to your human on the activation page.
        
```

## Only reads (2)

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

### `read_page`

- The name "read_page" says "read": a word for reading.
- Tag untrusted-input: The description's first sentence says "web": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Load a web page in a real browser and return its main content as clean
        markdown, with the title, canonical url and basic metadata. Handles
        javascript-rendered pages. Respects robots.txt and refuses sites that block
        automation rather than trying to defeat them. Pass api_key if you already have
        a pagewatch key, otherwise a free trial key is created for you on the first
        call and returned in the response.

        url: the page to read (http or https).
        api_key: an existing pagewatch bearer token, optional.
        wait_for_selector: css selector to wait for before reading, optional.
        scroll: scroll the page to trigger lazy-loaded content, optional.
        
```

### `screenshot`

- The name "screenshot" says "screenshot": a word for reading.
- Tag untrusted-input: The description's first sentence says "web": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Take a screenshot of a web page rendered in a real browser and return it as
        base64 image data (png by default, jpeg optional), with the final url and
        pixel size. Consent overlays are hidden so the shot shows the page. Respects
        robots.txt. Pass api_key if you have a pagewatch key, otherwise a free trial
        key is created for you and returned.

        url: the page to capture.
        api_key: an existing pagewatch bearer token, optional.
        full_page: capture the entire scrollable page, not just the viewport.
        width, height: viewport size in pixels.
        format: png or jpeg.
        wait_for_selector: css selector to wait for before capturing, optional.
        
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__pagewatch__read_page",
      "mcp__pagewatch__screenshot",
      "mcp__pagewatch__pdf",
      "mcp__pagewatch__register",
      "mcp__pagewatch__balance"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__pagewatch__read_page`: untrusted-input, outbound
- `mcp__pagewatch__screenshot`: untrusted-input, outbound
- `mcp__pagewatch__pdf`: outbound

- **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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://pagelens.dev/mcp: tools/list returned 5 tools to an anonymous client, including pdf (write), register (write), balance (write)
