## Findings

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

```untrusted-server-text
The server marks "analyze_deal" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "analyze_deal" says "analyze": a word for reading.
```


## Changes things (3)

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

### `analyze_deal`

- The name "analyze_deal" says "analyze": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Underwrite a real-estate investment deal and get a 0-100 score, verdict, cash flow, cap rate, DSCR, stress tests, break-even thresholds, and a shareable report link. Strategies: ltr (long-term rental), str (short-term rental), brrr, multifamily, flip (fix-n-flip), newc (new construction). All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Output is a software estimate, not financial, investment, tax or legal advice — figures are projections to verify, not recommendations. Free, no key; the response includes a shareable report_url.
```

### `best_use`

- 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
Screen ONE property across every strategy the provided inputs qualify for and rank them by deal score — answers "what is the best use of this property?". Provide a superset of inputs (price, marketRent, adr, occupancy, rehabBudget, arv, units, …); strategies missing inputs are skipped with reasons. All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Free, no key.
```

### `solve_max_offer`

- 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
Reverse-solve the Maximum Allowable Offer: the highest purchase price that still meets every return target (defaults: CoC 8%, DSCR 1.20, cash flow ≥ 0; flip: 10% after-tax margin + 15% annualized ROI). Returns the MAO, the binding constraint, and per-target price ceilings. Strategies: ltr, str, brrr, multifamily, flip. Provide the deal inputs WITHOUT committing to a price; an asking price or arv, if known, anchors the price-based defaults, and with neither those defaults (taxes, insurance, closing) follow each price tested. Override targets via the targets object. All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Free, no key.
```

## Only reads (1)

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

### `list_strategies`

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

Description, as the server wrote it:

```untrusted-server-text
List every supported strategy with its required and optional input fields. Call this first when unsure which inputs a strategy needs. Free, no key.
```
