```

```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__gakudosagashi__search_facilities",
      "mcp__gakudosagashi__get_facility",
      "mcp__gakudosagashi__list_wards",
      "mcp__gakudosagashi__search",
      "mcp__gakudosagashi__fetch"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__gakudosagashi__get_facility`: untrusted-input
- `mcp__gakudosagashi__fetch`: untrusted-input
