| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

```untrusted-server-text
The server marks "stock_call" 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 name "stock_call" says "call": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `unwatch`

- The description's first verb is "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Remove a US stock from the signed-in person's StockMap watchlists.
```

## Changes things (10)

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

### `bitcoin_test`

- 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
Did the person's coins beat Bitcoin: their holdings as they would paste them on StockMap's Bitcoin test page ("ETH 2, SOL 40 since Jan 15"), priced then and now beside the same dollars held in Bitcoin, from CoinGecko's prices. Nothing is stored. Market data with no call on any coin. Show the stamp, the sources and the not-advice line with the answer.
```

### `crypto_stocks`

- 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
Which US crypto stocks StockMap's model leans on: how many it leans outperform, neutral or underperform, how many of its graded two-week windows on them were right, and Bitcoin's move since the last US close. The calls are the stock model's, on the stocks, never on coins. Show the stamp, the sources and the not-advice line with the answer.
```

### `crypto_today`

- 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
Why crypto is up or down today, from StockMap's Crypto today page: Bitcoin's 24-hour move, how many coins beat it, funding, and the hour's paragraph, every number with its source. Market data with no call on any coin. Show the stamp, the sources and the not-advice line with the answer.
```

### `is_it_altseason`

- 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
Is it altseason: how many of the top-100 coins (stablecoins out) beat Bitcoin over the last 7 days, beside how many lag it in a typical week, from StockMap's Altseason page. Market data with no call on any coin. Show the stamp, the sources and the not-advice line with the answer.
```

### `last_night`

- 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
What changed in StockMap's calls last night: how many stocks' calls changed band on the market map and the biggest of them, the calls graded last night (made 14 days earlier) with one line on why each was right or wrong, and when the next run starts. Show the not-advice line and the run date with the answer.
```

### `market_map`

- 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
The US stock market on StockMap's map: the 11 sectors, each with its share of the market, its 2-week lean from the model's nightly calls on its stocks, its move on the day and its best and worst stock. A summary, not every stock. Use it when someone asks how the US market looks, or which sectors lead or lag, whether or not they name StockMap. Show the not-advice line and the run date with the answer.
```

### `my_watchlists`

- 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
The signed-in person's StockMap watchlists: each list's stocks with the model's call on each, the calls that changed last night first. Show the not-advice line and the run date with the answer.
```

### `sector`

- 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
StockMap's read of one US sector or industry, by name (Information Technology, semiconductors, banks): its 2-week lean from the model's nightly calls, how its stocks' calls split, its industries, and its largest stocks with each one's call and move on the day. Use it when someone asks how a US sector or industry looks, or which of its stocks look strong or weak, whether or not they name StockMap. Show the not-advice line and the run date with the answer.
```

### `stock_call`

- The name "stock_call" says "call": 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
StockMap's call on one US stock, by symbol or company name: the model's nightly 14-day call, the strongest reasons for and against, how its past calls on the stock did, the price and the day's change, and what changed last night. Use it when someone asks how a US stock looks, whether it is strong or weak right now, or what to make of it, whether or not they name StockMap. Show the not-advice line and the run date with the answer.
```

### `watch`

- The description's first verb is "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add a US stock to the signed-in person's StockMap watchlist: to the list named (made if it is new) or their first list. A stock is on one list at a time, so naming another list moves it.
```

## Only reads (1)

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

### `compare_stocks`

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

Description, as the server wrote it:

```untrusted-server-text
StockMap's calls on two to five US stocks side by side, by symbol or company name: each stock's nightly 14-day call, whether it changed last night, the insights for and against it, and how the model's past calls on it did. Use it when someone asks how two to five US stocks stack up against each other, or which of them looks stronger, whether or not they name StockMap. Show the not-advice line and the run date with the answer.
```
