## Findings

- **warn** Annotations that disagree with the tool in `create_video_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_video_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_video_link" says "create": a word for a change.
```


## Changes things (1)

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

### `create_video_link`

- The name "create_video_link" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Build a link that opens RewindMap's short-video maker preloaded with a map clip: borders (and optional event layers) changing from one year to another over a place, with an optional title and map labels. The visitor opens the link and taps Download to get a watermarked MP4 (vertical 9:16 for Shorts/Reels/TikTok, or landscape). Rendering happens in the visitor's browser; this tool returns the link only, never a video file.
```

## Only reads (3)

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

### `find_polity`

- The name "find_polity" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a state or empire by name or any of its Wikidata labels and aliases (substring, case-insensitive), or by Wikidata QID. Returns its lifespan, every border snapshot with its bounding box, and links.
```

### `search_events`

- The name "search_events" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date.
```

### `world_at_year`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List states, empires and cultures with an OpenHistoricalMap border snapshot in a given year, optionally overlapping a region. Coverage is incomplete; an empty result does not establish historical absence.
```

## Claude Code permissions
