## 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 `absorption_calc` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "absorption_calc" 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 (3)

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

### `absorption_calc`

- 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 Absorption development calculator on your inputs: total cost (land, hard, soft, construction interest, HUD fees), stabilized NOI, yield on cost and value, HUD 232 new construction loan (lowest of 90% of cost, the loan-to-value limit and 1.45x coverage), month-by-month lease-up to breakeven and stabilization, operating deficit and working capital escrows, and the equity left to fund. Unset inputs use the calculator page's example values.
```

### `rank_states`

- 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
Ranks all 50 states and DC on one senior housing measure: 75+ or 85+ population, 75+ or 85+ growth since April 2020, nursing home beds per 1,000 aged 85+, assisted living beds per 1,000 aged 75+, or HUD 232 new construction loans since FY2001. Each row also carries growth, both bed ratios, certificate of need status and the state page link.
```

### `state_demand_supply`

- 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
One state's (or DC's) senior housing development picture: Census 75+ and 85+ population (April 2020 and July 2025) and growth vs the US, CMS certified nursing home beds and CDC assisted living beds per 1,000 older adults vs the US, certificate of need status for nursing homes and assisted living, HUD Section 232 new construction loans since FY2001, and a county table (largest, fastest-growing or thinnest nursing supply), or one county by name.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `seniorhousingconstruction-loan`:

- **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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://seniorhousingconstruction.loan/mcp: tools/list returned 3 tools to an anonymous client, including state_demand_supply (write), rank_states (write), absorption_calc (write)
