## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `calculate_australia_super`

- 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
Projects an Australian superannuation balance to retirement (employer contributions, salary sacrifice, after-tax contributions, contribution tax and current caps, fees, inflation) and then retirement spending: the balance at retirement in nominal and today's dollars, a level annual budget, the gap to a target income and the age the money runs out. The Age Pension amount is an input; eligibility is not calculated. All fields are required; amounts in AUD, rates in percent per year.
```

### `calculate_retirement_income_gap`

- 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
Retirement income gap for one of 35 countries (nl, se, dk, no, fi, is, cz, at, ch, pt, us, cn, de, jp, in, fr, it, ca, br, ru, kr, mx, es, id, tr, sa, pl, be, ar, ie, ae, sg, il, th, nz): from accessible savings, monthly saving, retirement spending and up to three pension streams the user enters (after tax, in today's money), the savings at retirement, the capital needed, the capital gap, the first-year monthly gap and the age the money runs out. It does not calculate national pension entitlements. All fields are required; amounts in the country's currency (see list_retirement_calculators), rates in percent per year; use monthly 0 for unused pension streams.
```

### `calculate_uk_pension_drawdown`

- 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
Projects UK pension drawdown month by month: the pot after any upfront tax-free cash, first-year net income after an estimate of UK or Scottish income tax, the age the pot runs out (if it does) and the final balance. The user's State Pension forecast is an input; it is never inferred. All fields are required; amounts in GBP, rates in percent per year.
```

## Only reads (1)

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

### `list_retirement_calculators`

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

Description, as the server wrote it:

```untrusted-server-text
Lists Retirement Atlas's 37 countries: country code, currency, which calculation each uses (uk-drawdown, au-super or income-gap), the calculator page, the methodology and official reference sources. With a country code, returns that country only, with its full input schema.
```
