## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__propertycheck__check_address` `mcp__propertycheck__get_full_report` |
| 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 `get_full_report` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_full_report" destructive (destructiveHint: true), and its name says "get", a word for reading.

annotations: {"readOnlyHint":false,"destructiveHint":true,"idempotentHint":true,"openWorldHint":true}; The name "get_full_report" says "get": a word for reading.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `get_full_report`

- The name "get_full_report" says "get": a word for reading.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Full structured PropertyCheck JSON (propertycheck/2) for one covered address: identity, coverage, capabilities, a summary and up to twelve sections, with status and source details where available. Call after check_address shows a full report is available. No account or API key is required for one-off purchase: x402 returns a standard PaymentRequired (A$1.39 incl. GST); retry the same call with params._meta['x402/payment']. Coverage is checked before any charge, an address outside coverage is never charged, and retrying with the same idempotency_key or the same payment never charges twice. If the user has no wallet, ask for explicit agreement to the A$4.95 card price, then call the same tool with payment_method='card'; give checkout_url only to the human and poll this same tool with the returned purchase_id and access_token. Never create a second checkout for that purchase. Existing B2B API-key accounts remain supported. After an API-key or x402 purchase, pass report_id instead of address to re-view the same report at zero cost; x402 re-view also carries the original payment proof. Optional sections limits the output; detail='full' restores heavy enumerations from the same stored report, with no second charge.
```

## Changes things (1)

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

### `check_address`

- 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 untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
FREE, no key. Use when you have one specific street address in the City of Gold Coast or Brisbane City (Queensland, Australia) and need to understand the property and what surrounds it before renting, buying, relocating, working or studying there. Returns coverage and a short summary: up to five findings and up to two items that could not be verified, each with a status; source where available. Depending on the address and available evidence, findings may cover hazards or planning. Brisbane findings may include the street and its traffic, parking, frontage or road-reserve context, or parent-building height where verified. Gold Coast free checks do not promise paid-only physical context, including frontage, carriageway width, parking or building measurements. Any suburb of those two councils works, for example Surfers Paradise, Robina, Coomera, Kangaroo Point, New Farm or Chapel Hill. Addresses elsewhere are reported as outside coverage. Not for listing search, valuations, mortgages or price forecasts. Never charges.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__propertycheck__check_address"
    ],
    "deny": [
      "mcp__propertycheck__get_full_report"
    ]
  }
}
```

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

- `mcp__propertycheck__check_address`: untrusted-input
- `mcp__propertycheck__get_full_report`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:19:01.541Z, unchanged since 2026-10-22T14:19:01.541Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 2 tools that change things (1 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://agents.alphaquantlabs.ai/v1/mcp: tools/list returned 2 tools to an anonymous client, including get_full_report (destructive), check_address (write)
```
