## 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__archive__get_catalogue_export` `mcp__archive__get_provenance` |
| 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.

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__archive__get_cedwyn_guide",
      "mcp__archive__search_cedwyn_names",
      "mcp__archive__list_cedwyn_ebooks",
      "mcp__archive__read_cedwyn_page",
      "mcp__archive__get_catalogue_export",
      "mcp__archive__get_provenance",
      "mcp__archive__list_open_agent_jobs"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__archive__get_catalogue_export`: private-data
- `mcp__archive__get_provenance`: private-data
