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

| Tag | Meaning | Tools |
| --- | --- | --- |
| 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__visibly-ai__analyze_url_structure` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__visibly-ai__analyze_url_structure` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `classify_keywords_simple`

```untrusted-server-text

## Only reads (6)

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

### `analyze_url_structure`

- The name "analyze_url_structure" says "analyze": a word for reading.
- Tag untrusted-input: The name "analyze_url_structure" says "analyze" and "url": it reads web pages, which anyone can write. The description's first sentence says "analyze" and "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.
