## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__praetorium__get_reference` `mcp__praetorium__list_reference` |
| 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 `simulate_combat` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "simulate_combat" 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 description's first verb is "run": a word for a change.
```


## Deletes or cancels (4)

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

### `create_battle`

### `save_roster`

- The name "save_roster" says "save": a word for a change.
- The server marks it destructive (destructiveHint: true).

Saves a complete roster. Pass its id to edit an owned roster; omit id to create one. limit is the battle size (1000, 2000 or 3000 points, or 600 for King of the Colosseum), which sets detachment points, enhancement and unit limits. pointsBudget optionally replaces only its points total (500 to 10000, not King of the Colosseum); omit it to keep a saved budget, or send null for the standard total. Requires mcp:write.
```

### `set_roster_visibility`

- The name "set_roster_visibility" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).

```untrusted-server-text
Appends a legal battle command only when expectedSeq matches the current log. Requires mcp:write.
```

## Changes things (1)

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

### `simulate_combat`

- The description's first verb is "run": 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
Runs Praetorium's exact combat simulator for one attacking unit, with any attached leaders, against one defending unit at full strength: shooting, melee, and shooting followed by melee. Returns expected models destroyed, expected wounds lost, the chance to destroy the unit, cumulative odds, weapons used, the rule and weapon-mode choices each side can change, datasheet citations, and a simulator link. Passive datasheet rules apply by default; stratagems and conditional rules stay off until chosen. Unsupported mechanics are refused or listed under notCalculated rather than approximated. Like the standalone simulator page, it uses default loadouts and no detachment; unit sizes and attachments must be legal.
```

```

### `get_reference_record`

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

Description, as the server wrote it:

```untrusted-server-text

Include a detachment to receive its rules, enhancements, upgrades, and stratagems by name, cost, and timing without opening every unit page. Their rules text is at each record’s textSources.
```

### `search_reference`

- The name "search_reference" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
