## 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.

### `size_loan`

- 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
The studenthousing.loans by-the-bed loan sizer: from beds, rent per bed, months collected, vacancy, expenses, reserves, value and your own interest rate, returns net operating income and the loan allowed by max LTV, min DSCR and an optional debt yield, the maximum loan (the smallest), which test binds, annual debt service and loan per bed. Presets are Freddie Mac's published student housing LTV/DSCR tiers.
```

## Only reads (2)

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

### `get_campus`

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

Description, as the server wrote it:

```untrusted-server-text
One US four-year campus (3,000+ full-time students) from federal IPEDS data: fall 2024 enrollment (total, full-time, undergraduate, graduate, online share, change from 2023), college-controlled housing beds for 2024-25, beds per 100 full-time students, the bed gap, typical housing and food charges, aid-office housing budgets, and whether it meets Fannie Mae's 10,000-student campus-size test. Find it by name (with optional state) or IPEDS UNITID.
```

### `search_campuses`

- The name "search_campuses" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists US four-year campuses (3,000+ full-time students) filtered by state, city, name words, sector, whether the college offers housing, Fannie Mae campus-size test, or minimum full-time enrollment, ranked by bed gap, enrollment, college beds, beds per 100 students or housing charge. Each row gives fall 2024 enrollment, 2024-25 college-controlled beds, bed gap, housing charge and the campus page link.
```

## Claude Code permissions

- **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://studenthousing.loans/mcp: tools/list returned 3 tools to an anonymous client, including size_loan (write)
