## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| --- | --- | --- |
| 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 |

## Findings

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

```untrusted-server-text
The server marks "capital_stack" 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 (1)

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

### `capital_stack`

- 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 cre.capital stack builder on a deal: senior loan, mezzanine, preferred equity and the common equity left over, with an optional one-tier JV split. Returns each layer's amount, share of cost and attachment/detachment LTV and LTC, blended cost of capital, cost of debt and preferred, common equity IRR and multiple, unlevered IRR, senior and all-debt DSCR, coverage including pref current pay, debt yields, LP and sponsor IRRs, the exit and the yearly cash flows. Rates you leave out start from the current 10-year Treasury plus Altus Group Q2 2026 average quotes. Arithmetic on your inputs, not a quote or a projection.
```

## Only reads (2)

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

### `get_capital_costs`

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

Description, as the server wrote it:

```untrusted-server-text
What senior debt, mezzanine and preferred equity cost: Altus Group's Q2 2026 average lender quotes (fixed and floating, by LTV band, as spreads over the 5-year or 10-year Treasury or Term SOFR), the current 10-year Treasury with the implied all-in senior and mezzanine rates, and what public mortgage REITs report earning on each layer in their 10-Qs for the quarter ended June 30, 2026. Filter by layer.
```

### `list_capital_providers`

- The name "list_capital_providers" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Names of firms in the business of each layer, only as the institutions publish them: Fannie Mae DUS lenders and Freddie Mac Optigo lenders (senior agency multifamily debt) and public mortgage REITs that hold mezzanine loans or preferred equity per their 10-Qs. Filter by list or by part of a name. Being on a list does not mean a firm will quote a given deal.
```
