| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__hyperstore__search_apps` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__hyperstore__browse_apps` `mcp__hyperstore__get_app` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__hyperstore__search_apps",
      "mcp__hyperstore__ai_search",
      "mcp__hyperstore__get_app",
      "mcp__hyperstore__list_apps",
      "mcp__hyperstore__list_categories",

      "mcp__hyperstore__apps_for_use_case"
    ],
    "ask": [],
    "deny": []
  }
}

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

- `mcp__hyperstore__search_apps`: private-data
- `mcp__hyperstore__get_app`: untrusted-input
- `mcp__hyperstore__browse_apps`: untrusted-input
