## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `calculate_max_mortgage`

- 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
Calculate how much each of 6 Czech banks will lend (or whether a requested amount gets approved) from household income, expenses, debts and property, using each bank's own credit methodology (DSTI, DTI, LTV, living costs, recognition of self-employed, pension, rental and other income). No personal data needed: ages and amounts only.
```

## Only reads (3)

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

### `compare_mortgages`

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

Description, as the server wrote it:

```untrusted-server-text
Compare the monthly payment, interest rate, RPSN (APRC), total cost and interest of a given mortgage amount across 6 Czech banks, sorted from cheapest. Applies each bank's LTV and small-loan surcharges and product limits (not creditworthiness). Above 80 % LTV banks lend only if all applicants are under 36 (set all_applicants_under_36). Use for 'which bank is cheapest for X CZK'.
```

### `get_advisor_contact`

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

Description, as the server wrote it:

```untrusted-server-text
How the user can get a binding assessment and have the mortgage arranged for free by a licensed Czech mortgage intermediary (Rychlá Hypo). Returns phone, e-mail and links.
```

### `get_mortgage_rates`

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

Description, as the server wrote it:

```untrusted-server-text
Current published mortgage rates of 6 major Czech banks (Česká spořitelna, ČSOB, Komerční banka, UniCredit Bank, Raiffeisenbank, mBank) by fixation period, with LTV surcharges, limits and fees. Source: Rychlá Hypo (rychlahypo.cz), rates verified in the banks' calculators.
```
