## 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

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```


## Changes things (2)

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

### `size_park_loan`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs the Pad Count loan sizer on one mobile home park: for Fannie Mae MHC, Freddie Mac MHC, HUD 223(f) MHC and the user's own bank or CMBS terms it returns a verdict (fits, check first, doesn't fit), the loan amount (the smaller of value x max LTV and NOI / (coverage x loan constant)), which limit binds, the rate used (Treasury for the term plus a spread) and every published rule the park fails. SBA 7(a) and 504 come back as not eligible, with the SOP quote.
```

### `value_park_on_lot_rent`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs the Pad Count lot-rent valuation worksheet: from pads, occupancy, lot rent, park-owned homes, other income and expenses it returns collected income, operating expenses, NOI, NOI from lots alone, value at the low, middle and high of a cap rate range the user supplies, value per pad, and the lender flags (85% occupancy, park-owned home share against the 25%/35% agency caps, pad minimums, Fannie Mae 5% economic vacancy floor, park-paid utilities).
```

## Only reads (2)

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

### `get_mhc_loan_program_rules`

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

Description, as the server wrote it:

```untrusted-server-text
The published rules for financing a mobile home park (manufactured housing community) under Fannie Mae MHC, Freddie Mac Optigo MHC, HUD Section 223(f) MHC and SBA 7(a)/504: max LTV, min DSCR, amortization, minimum size, occupancy, park-owned home caps, borrower eligibility, reserves and mortgage insurance, each with its primary source and date. SBA comes back as not eligible, with the SOP quote.
```

### `get_new_manufactured_home_prices`

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

Description, as the server wrote it:

```untrusted-server-text
The U.S. Census Bureau Manufactured Housing Survey average sales price of a new manufactured home, by month of shipment: single-section, double-section and all homes for the latest month published and the months before it. A yardstick for what filling a vacant pad with a new park-owned home costs.
```

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