## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__fixandflip-loans__get_lender_terms` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__fixandflip-loans__compare_lender_costs` `mcp__fixandflip-loans__find_lenders` `mcp__fixandflip-loans__get_lender_terms` |
| 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 `calculate_flip_profit` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_flip_profit" 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.

### `calculate_flip_profit`

- 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 fixandflip.loans calculator on a deal: profit, cash you put in, return on cash (and simple annualized), profit as % of ARV, the hard-money loan with interest, points and fees, holding and selling costs, the 70% rule maximum price and whether the deal meets it, and the breakeven sale price. Optionally prices the loan at a listed lender's advertised starting rate.
```

## Only reads (3)

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

### `compare_lender_costs`

- The name "compare_lender_costs" says "compare": a word for reading.
- Tag untrusted-input: The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Prices one flip at each listed lender's advertised fix-and-flip starting rate (from its own website, read 2026-10-24), ranked by profit: interest cost, total financing and profit per lender, with your own leverage, points and fees held the same. Optional state keeps only lenders that list it (plus those to check).
```

### `find_lenders`

- The name "find_lenders" says "find": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Lists the hard-money and DSCR lenders on fixandflip.loans whose own websites (read 2026-10-24) say they lend in a state, with starting rate, leverage, minimum credit score, experience rule, loan size and a source link each. Lenders that publish no state list are returned as "check".
```

### `get_lender_terms`

- The name "get_lender_terms" says "get": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes.
- Tag untrusted-input: The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Everything fixandflip.loans recorded from one lender's own website (read 2026-10-24): fix-and-flip and DSCR rates, leverage, points, terms, credit and experience rules, loan sizes, the states it lends in, license line, notes and the exact source pages.
```

## Claude Code permissions

    ],
    "ask": [
      "mcp__fixandflip-loans__calculate_flip_profit"
    ],

- `mcp__fixandflip-loans__find_lenders`: untrusted-input
- `mcp__fixandflip-loans__get_lender_terms`: private-data, untrusted-input

- **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://fixandflip.loans/mcp: tools/list returned 4 tools to an anonymous client, including calculate_flip_profit (write)
