## 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 `convert_odds` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_odds" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true}; The name "convert_odds" says "convert": a word for a change.
```

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

```untrusted-server-text
The server marks "parlay_payout" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true}; The name "parlay_payout" says "payout": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `parlay_payout`

- The name "parlay_payout" says "payout": a word that usually means money moves, which cannot be taken back.
- 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
Payout of a parlay (accumulator) of 2 to 20 legs that all win: combined decimal odds = product of leg decimals; payout = stake * combined; profit = payout - stake; combined implied probability = 1 / combined (legs assumed independent). For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

## Changes things (3)

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

### `convert_odds`

- The name "convert_odds" says "convert": 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
Convert betting odds between american (+150, -110), decimal (2.5), fractional (3/2) and implied probability (0.4 or 40%). Decimal d = 1 + n/d for fractions, 1 + a/100 for +a, 1 + 100/a for -a; implied probability = 1/decimal. Pure math, no data lookup. For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

### `expected_value`

- 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
Expected value of a wager from odds and your own win probability (percent, 0-100). EV = stake * (p*(decimal-1) - (1-p)); break-even probability = 1/decimal; edge = p - break-even. The probability is your input, not a prediction by BetsBeats. For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

### `verify_pick`

- 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
Verify a sealed BetsBeats pick from its SHA-256 commitment hash (full 64 hex characters, or a prefix of 16 or more). Before the pick settles this only confirms the hash exists and returns sealed_at and kickoff_at. After settlement it returns the revealed preimage, recomputes SHA-256 on the server and reports matches=true/false, plus the result and a verify_url. For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

## Only reads (2)

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

### `get_record`

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

Description, as the server wrote it:

```untrusted-server-text
The public running record of the BetsBeats main pick: wins, losses, voids (a void is a push or no pick), the current streak and the date range, exactly as shown on the results page. Losses are included. For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

### `get_results`

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

Description, as the server wrote it:

```untrusted-server-text
Settled BetsBeats picks for one day (YYYY-MM-DD): the main pick and extras with commitment hashes, selections, odds and results. Only days that are already settled and public are returned. For adults 21+ only. Entertainment and analysis; no wins are promised and past results do not predict future ones. BetsBeats does not take bets.
```

## Claude Code permissions
