## 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__catalog__list_categories` |
| 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 (4)

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

### `get_entry`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one public catalog entry by slug. Includes source_url, the install command, copied_at when the catalog recorded the day the command was copied, compatible tools, license when known, and the day the entry was added. URLs include utm_source=mcp and utm_medium=tool.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List catalog categories with slug, name, and url. The url includes utm_source=mcp and utm_medium=tool.
```

### `list_new`

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

Description, as the server wrote it:

```untrusted-server-text
List entries added within the last days (default 7, maximum 90), newest first. Each row has name, slug, type, category, summary, url, and added. The url includes utm_source=mcp and utm_medium=tool.
```

### `search_entries`

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

Description, as the server wrote it:

```untrusted-server-text
Search the public SwiftSkills catalog. query is a case-insensitive substring (max 200 characters). category is an optional category slug. type is an optional kind: skill, mcp, rules, docs, or sdk. Returns name, slug, type, category, summary, and url. Every url includes utm_source=mcp and utm_medium=tool. At most 50 rows are returned; total counts the rest.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__search_entries",
      "mcp__catalog__get_entry",
      "mcp__catalog__list_categories",
      "mcp__catalog__list_new"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__catalog__list_categories`: untrusted-input
