## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__scorekeeper__create_scoreboard` `mcp__scorekeeper__update_scoreboard` |
| 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 `hand_off_scoreboard` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "hand_off_scoreboard" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "return": a word for reading.
```


## Deletes or cancels (1)

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

### `update_scoreboard`

- The name "update_scoreboard" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Atomically set exact scores, increment scores, rename teams or change title. Use stable team IDs and the last read revision. Updates immediately appear publicly. On revision_conflict read the board and decide again; do not blindly replay a stale increment. Identical retry IDs return the previous result.
```

## Changes things (2)

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

### `create_scoreboard`

- The name "create_scoreboard" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Create a public, shareable two-team scoreboard at zero. Requires explicit user intent to create; title and team names are public. Free boards allow 50 total spectator views and show branding. Retry the identical requestId and input after a timeout.
```

### `hand_off_scoreboard`

- The description's first verb is "return": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Return the connected account owner’s private management link. Share it only with the intended scorer, never spectators. Does not transfer ownership. Reuse requestId on retry.
```

## Only reads (2)

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

### `get_scoreboard`

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

Description, as the server wrote it:

```untrusted-server-text
Read a scoreboard created through this API by the connected account, including stable team IDs and current revision.
```

### `list_scoreboards`

- The name "list_scoreboards" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the connected account's API-created generic scoreboards. Does not list unrelated legacy boards. Pass nextCursor as cursor to continue until null; a filtered page can be empty.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__scorekeeper__get_scoreboard",
      "mcp__scorekeeper__list_scoreboards"
    ],
    "ask": [
      "mcp__scorekeeper__create_scoreboard",
      "mcp__scorekeeper__hand_off_scoreboard"
    ],
    "deny": [
      "mcp__scorekeeper__update_scoreboard"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__scorekeeper__create_scoreboard`: untrusted-input
- `mcp__scorekeeper__update_scoreboard`: untrusted-input
