## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `create_proposals`

- The name "create_proposals" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Scan for anomalies and file them as DRAFT proposals in JaKonto for a human to approve. Never writes to the accounting system. Idempotent per open finding.
```

### `profit_and_loss`

- 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
Resultatopgørelse (profit and loss) for a period: revenue and expense lines, result (øre).
```

### `vat_by_quarter`

- 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
Output VAT, input VAT and VAT payable per quarter (øre) from the synced invoices.
```

## Only reads (3)

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

### `list_connections`

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

Description, as the server wrote it:

```untrusted-server-text
The accounting systems this API key can read (e-conomic, Dinero, Billy …): id, system, company.
```

### `list_invoices`

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

Description, as the server wrote it:

```untrusted-server-text
One page of invoices from the accounting system, canonical model (amounts in øre). Pass next_cursor back as cursor for the next page.
```

### `list_proposals`

- The name "list_proposals" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

```untrusted-server-text
Bookkeeping proposals waiting for (or past) human review.
```
