## 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 (3)

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

### `expiring_contracts`

- 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
Active HUD project-based Section 8 and assistance contracts (HAP, PRAC, RAC, PAC) in one state whose overall or current expiration date falls in a date window, with property name, city, county, assisted units, program, both expiration dates, rent-to-FMR ratio and FHA number. Filter by county, city, contract type and size; page through results.
```

### `screen_below_fmr`

- 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 deal screen's rent test for one state: active Section 8 HAP contracts whose rent-to-FMR ratio in HUD's file is above zero and under a threshold (default 90%), with property, assisted units, ratio, both expiration dates and a prefilled offer-calculator link. Optional filters: county, city, minimum assisted units, overall expiration within N months.
```

### `state_contract_summary`

- 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
Deal-screen counts for one state, or every state ranked: properties, active contracts and assisted units, contracts reaching final (overall) expiration within two years of the HUD file date with their assisted units, and HAP contracts paying under 90% of Fair Market Rent. Omit state for the national ranking.
```

## Only reads (1)

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

### `get_property`

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

Description, as the server wrote it:

```untrusted-server-text
One HUD Section 8 or assistance property with every contract on it: address, county, total units, HUD property category and financing type, FHA number, and per contract the number, program, status, effective date, both expiration dates, term, assisted units and rent-to-FMR ratio. Look up by contract number, HUD property ID, or property name within a state.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__multifamily-deals__get_property"
    ],
    "ask": [
      "mcp__multifamily-deals__expiring_contracts",
      "mcp__multifamily-deals__screen_below_fmr",
      "mcp__multifamily-deals__state_contract_summary"
    ],
    "deny": []
  }
}
```

- **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://multifamily.deals/mcp: tools/list returned 4 tools to an anonymous client, including expiring_contracts (write), screen_below_fmr (write), state_contract_summary (write)
