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

```untrusted-server-text
The server marks "generate_fair_lineup" 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 "generate_fair_lineup" says "generate": a word for a change.
```

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

```untrusted-server-text
The server marks "generate_round_robin" 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 "generate_round_robin" says "generate": a word for a change.
```


## Changes things (4)

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

### `calculate_playing_time`

- 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 minutes and percentage per player, bench size, a simple segment length and whether equal shares meet a 50% minimum. This is an equal-share calculation, before any goalkeeper constraints.
```

### `generate_fair_lineup`

- The name "generate_fair_lineup" says "generate": 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
Create a deterministic rotation with balanced minutes, goalkeeper duties and preferred positions. Returns each substitution window, player minutes and a shareable printable link. Duplicate names receive numbered suffixes. Without designated goalkeepers, everyone is available in goal.
```

### `generate_round_robin`

- The name "generate_round_robin" says "generate": 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
Create deterministic weekly fixtures for 3–24 teams with balanced home/away games and odd-team byes. Double round-robin reverses the round order and swaps home/away for the return leg. Returns fixtures, team counts, a Markdown table and a share link.
```

### `recommend_formation`

- 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
Choose a formation for 7v7 (U8–U10), 9v9 (U11–U12) or 11v11 (U13+), with alternatives and coaching notes. Explicit format takes precedence over age; defaults to balanced 7v7.
```

## Only reads (1)

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

### `age_group`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the age group for a birth date, governing body and season from published official cutoff rules. Covers US Youth Soccer, AYSO, The FA and Canada Soccer from 2026. Returns the cutoff source and calculator link. USYS and AYSO use the revised August–July window from 2026–27.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `lineups`:

```json

  "permissions": {
    "allow": [
      "mcp__lineups__age_group"
    ],
    "ask": [
      "mcp__lineups__generate_fair_lineup",
      "mcp__lineups__recommend_formation",
      "mcp__lineups__calculate_playing_time",
      "mcp__lineups__generate_round_robin"
    ],
    "deny": []
