## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `rank_wine_companies`

- 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
Every listed wine company VINCAP tracks (index constituents and tracked companies), ranked on the weights you set, 0-5 each: growth (revenue growth, latest period), margin (net margin), y1 (1-year share price), wine (wine share of revenue), from_high (further below the 52-week high scores higher). Each company scores by its percentile inside the universe; one missing a weighted figure is listed unscored, never scored as zero. Each row carries the figures and the results period. Example: {"weights":{"growth":2,"margin":3},"include":"index"}
```

## Only reads (4)

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

### `get_estates`

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

Description, as the server wrote it:

```untrusted-server-text
Which estates, wineries and vineyards a listed wine company owns. Free: the count and names. The full monthly record with history and source probes: the paid x402 route in `paid`. Example: {"symbol":"TWE.AX"}
```

### `get_investor_calendar`

- The name "get_investor_calendar" says "get": a word for reading.
- Tag private-data: The name "get_investor_calendar" says "get" and "calendar": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
The next results dates, AGMs and dividends of listed wine companies, from issuer and exchange sources. Free: the next 5 rows. The full calendar with recorded outcomes: the paid x402 route in `paid`. Example: {"symbol":"TWE.AX"}
```

### `get_wine_company`

- The name "get_wine_company" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One listed wine company by symbol: latest reported result lines (revenue, operating and net result) with the source URL and locator they were read from, and its next investor event. Example: {"symbol":"TWE.AX"}
```

### `get_wine_stock_index`

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

Description, as the server wrote it:

```untrusted-server-text
The VINCAP Wine Stock Index (BCWINE): live level, published close, constituents with symbol, country, exchange and weight. Prices are delayed. Example: {}
```
