## Findings

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

```untrusted-server-text
The server marks "grotax_health_check" 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 (4)

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

### `grotax_compute_ct`

- 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
Estimate UAE Corporate Tax using the Grovisor computation (rows A–K): AED 375,000 0% band then 9%, 50% entertainment add-back, interest cap (higher of AED 12m or 30% of adjusted EBITDA), 75% loss relief, Small Business Relief, simplified QFZP and WHT/FTC credits. Only accountingProfit is required; pass revenue to test SBR. Returns a markdown table plus structured rows. Indicative, not tax advice.
```

### `grotax_health_check`

- 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
Run the Grovisor CT reviewer red-flag checklist (SBR, free zone/QFZP, TP disclosure and Local/Master File, connected-person pay, related-party loans, entertainment, fines, interest cap, loss continuity, audit threshold, exempt income). Pass the answers you know; call grotax_list_health_questions first for the keys and allowed values. Returns findings ranked High → Low.
```

### `grotax_qfzp_de_minimis`

- 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
Test whether a free zone company's non-qualifying revenue stays within the de minimis limit: the lower of 5% of total revenue or AED 5m (MD 229 of 2025). Failing it ends Qualifying Free Zone Person status for that period and the next 4.
```

### `grotax_tp_thresholds`

- 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
Check which UAE transfer pricing documents apply: TP Disclosure Form (related-party transactions > AED 40m with a category > AED 4m, or connected-person payments > AED 0.5m), Local File + Master File (revenue > AED 200m or MNE group).
```

## Only reads (4)

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

### `grotax_compare_sbr`

- The name "grotax_compare_sbr" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compute the same facts with and without Small Business Relief (revenue ≤ AED 3m, periods ending by 31 Dec 2029). Shows tax payable and what carries forward each way: in an SBR year a tax loss and disallowed interest are forfeited. Takes the same inputs as grotax_compute_ct (sbrElect is ignored).
```

### `grotax_get_rules`

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

Description, as the server wrote it:

```untrusted-server-text
List every rate and threshold groTAX uses, with its legal source and whether it still needs verification (verify: true).
```

### `grotax_list_health_questions`

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

Description, as the server wrote it:

```untrusted-server-text
List the groTAX health-check questions with their answer keys and allowed values, including which questions only apply after others (dependsOn). Use before grotax_health_check.
```

### `grotax_penalties`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return and payment due date (9 months after period end) and estimated penalties: late filing AED 500 a month for 12 months then AED 1,000, late payment 14% a year charged monthly (from 14 Apr 2026), AED 10,000 late registration, waived if the first return is filed within 7 months of the end of the first tax period. Blank filing date = today; blank payment date = filing date.
```
