## 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__przilla__get_workout` |
| 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

No check matched anything in these tool definitions.


## Only reads (3)

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

### `get_workout`

- The name "get_workout" says "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
Get a public workout by its exact name or PRzilla slug, including its prescription, scaling notes, movements, and L2–L10 benchmark thresholds for available men's, women's, and vest variants. No personal scores are available.
```

### `search_movements`

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

Description, as the server wrote it:

```untrusted-server-text
Look up one canonical movement name or alias, such as HSPU or thruster. Returns equipment, technique description, easier versions, progressions, a demo video when available, and example PRzilla workouts. These are catalog suggestions, not personalized prescriptions.
```

### `search_workouts`

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

Description, as the server wrote it:

```untrusted-server-text
Search the public PRzilla workout catalog by workout name or movement. Optionally filter by category. Returns workout links and short summaries; use get_workout for prescriptions and benchmark targets. Does not search an athlete's workout history.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__przilla__search_workouts",
      "mcp__przilla__get_workout",
      "mcp__przilla__search_movements"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__przilla__get_workout`: private-data
