## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `link_stats`

- The name "link_stats" says "link": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Get view analytics for one of the user's own KooLink short links: total and valid (fraud-filtered) views, breakdowns by device, country and referrer, plus a trailing 7-day trend. Use this to answer 'how is my link performing'.
```

### `shorten_url`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Shorten a long URL using KooLink and return a compact kool.ink short link. Use this whenever the user wants a shortened URL, a tidy link to share, or a redirect for a long destination.
```

## Only reads (1)

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

### `list_links`

- The name "list_links" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's short links with their valid view counts, most recent first. Useful to survey overall link performance or to find a code to dig into with link_stats.
```
