## 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__dubai-property__get_listing` `mcp__dubai-property__search_listings` `mcp__dubai-property__submit_enquiry` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__dubai-property__submit_enquiry` |

## Findings

- **warn** Annotations that disagree with the tool in `calculate_purchase_costs` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_purchase_costs" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "calculate_purchase_costs" says "purchase": a word that usually means money moves, which cannot be taken back.

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 8 tools that change things (2 irreversible, 6 write). Whether a call also works without credentials was not tested: tools are never called.
