**4 tools: 2 change things and 2 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__ncrypt__ncrypt_get_view_analytics` `mcp__ncrypt__ncrypt_list_documents` |
| 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. | `mcp__ncrypt__ncrypt_create_share_link` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `ncrypt_add_share_link`

- The name "ncrypt_add_share_link" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an additional share link for a document that already exists. A document can be shared as many times as needed. Each link carries its own code and trace code, so the view history records which share each viewer came through.
```

### `ncrypt_create_share_link`

- The name "ncrypt_create_share_link" says "create": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Upload a document to Ncrypt and return a private share link. The recipient must enter their name and a valid email address before they can read a single page, the file is encrypted at rest, and downloads are denied until the owner approves them. Supply the file as base64 content, a public https URL, or a path in the owner's own storage.
```

## Only reads (2)

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

### `ncrypt_get_view_analytics`

- The name "ncrypt_get_view_analytics" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Return who viewed a document, when, on what device and for how long.
```

### `ncrypt_list_documents`

- The name "ncrypt_list_documents" says "list": a word for reading.
- Tag private-data: The name "ncrypt_list_documents" says "list" and "document": it reads documents. The description's first sentence says "list" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
List the documents in the owner's Ncrypt workspace with their share codes and view counts.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__ncrypt__ncrypt_list_documents",
      "mcp__ncrypt__ncrypt_get_view_analytics"
    ],
    "ask": [
      "mcp__ncrypt__ncrypt_create_share_link",
      "mcp__ncrypt__ncrypt_add_share_link"
    ],
    "deny": []
  }
}
```

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

- `mcp__ncrypt__ncrypt_create_share_link`: outbound
- `mcp__ncrypt__ncrypt_list_documents`: private-data
- `mcp__ncrypt__ncrypt_get_view_analytics`: private-data

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://ncrypt.me/api/mcp: tools/list returned 4 tools to an anonymous client, including ncrypt_create_share_link (write), ncrypt_add_share_link (write)
```
