## Exfil surface

36 private-data -> untrusted-input -> outbound paths in this server alone. Denying 3 untrusted-input tools breaks every one: `mcp__website-contact-extractor__check_url`, `mcp__website-contact-extractor__extract_contacts`, `mcp__website-contact-extractor__find_social_profiles`.

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `extract_contacts_bulk`

- 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.
- Tag outbound: The input takes a URL (input.urls): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
One call for a lead list: each site gets homepage + contact pages (max_pages), results per site plus a summary (sites with email/phone/WhatsApp, failures). Charged per page fetched across all sites. Example: urls ['a.com','b.ae'], max_pages 2, region 'AE'. Response: result with emails[] (email, source, role), phones[] (e164, international, region, type, source), whatsapp[], social{platform: [url, handle]}, addresses[], organization{}, pages[] (what was fetched, status) and summary{}, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. Charged per page actually fetched; failed fetches are free. URLs are not logged.
```

### `extract_from_html`

- 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
Same parser, no fetching: emails (incl. obfuscated 'name [at] domain [dot] com'), phones, WhatsApp, social links, addresses, schema.org organisation data, and the contact-page links present. Free. Example: html '<a href="mailto:x@y.com">'. Response: result with emails[] (email, source, role), phones[] (e164, international, region, type, source), whatsapp[], social{platform: [url, handle]}, addresses[], organization{}, pages[] (what was fetched, status) and summary{}, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. Charged per page actually fetched; failed fetches are free. URLs are not logged.
```

## Only reads (3)

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

### `check_url`

- The description's first verb is "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "contact": it reads contacts.
- Tag untrusted-input: The name "check_url" says "url": it reads web pages, which anyone can write. The description's first sentence says "get" and "url": 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
GET the URL (robots-respecting, public hosts only) and report status, final URL after redirects, content type, title, declared languages and whether a contact page is linked. Use before a bulk job or to clean a URL list. Example: url 'example.com'. Response: result with emails[] (email, source, role), phones[] (e164, international, region, type, source), whatsapp[], social{platform: [url, handle]}, addresses[], organization{}, pages[] (what was fetched, status) and summary{}, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. Charged per page actually fetched; failed fetches are free. URLs are not logged.
```

### `extract_contacts`

- The description's first verb is "fetch": a word for reading.
- Tag private-data: The name "extract_contacts" says "contact": it reads contacts. The description's first sentence says "fetch" and "contact": it reads contacts.
- Tag untrusted-input: The description's first sentence says "fetch" and "email": it reads inbound email, which other people 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
Fetch a site's homepage and up to max_pages-1 contact/about pages and return every email, phone (validated, E.164, type), WhatsApp link, social profile, postal address and organisation field found, with provenance per item. Example: url 'noahsarch.tech', max_pages 3, region 'AE'. Response: result with emails[] (email, source, role), phones[] (e164, international, region, type, source), whatsapp[], social{platform: [url, handle]}, addresses[], organization{}, pages[] (what was fetched, status) and summary{}, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. Charged per page actually fetched; failed fetches are free. URLs are not logged.
```

### `find_social_profiles`

- The name "find_social_profiles" says "find": a word for reading.
- Tag private-data: The description's first sentence says "thread": it reads messages.

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `website-contact-extractor`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__website-contact-extractor__extract_contacts",
      "mcp__website-contact-extractor__find_social_profiles",
      "mcp__website-contact-extractor__extract_contacts_bulk",
      "mcp__website-contact-extractor__extract_from_html",
      "mcp__website-contact-extractor__check_url"
    ],
    "deny": []
  }
}
```

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

- `mcp__website-contact-extractor__extract_contacts`: private-data, untrusted-input, outbound
- `mcp__website-contact-extractor__find_social_profiles`: private-data, untrusted-input, outbound
- `mcp__website-contact-extractor__extract_contacts_bulk`: outbound
- `mcp__website-contact-extractor__check_url`: private-data, untrusted-input, outbound

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.
