| 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__foundplay__search_games` |
| 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 (1)

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

### `search_games`

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

Description, as the server wrote it:

```untrusted-server-text
Searches the free browser games listed on Foundplay, made by independent creators, many of them with AI tools. Matches the query against each game's title, one-line description and genres. Returns each match's title, description, genres, whether it plays on phones, whether people can play it together, play and upvote counts, the creator's X handle when known, and a link to its Foundplay page. Read-only. With no query, returns the most played games.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__foundplay__search_games"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__foundplay__search_games`: untrusted-input
