## Findings

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

```untrusted-server-text
The server marks "convert_time" 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 "convert_time" says "convert": a word for a change.
```


## Changes things (1)

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

### `convert_time`

- The name "convert_time" says "convert": 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
Given a UTC instant (or a wall time in a source location), return the corresponding local time in each of up to 50 target locations. Results include a source_url linking the matching worldclock.pro page when available.
```

## Only reads (4)

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

### `get_current_time`

- The name "get_current_time" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the current local time (or the time at a given instant) in one or more locations. Each location is a city name, an IANA timezone / abbreviation, or coordinates. Up to 50 locations. Results include a source_url linking the matching worldclock.pro page when available.
```

### `get_dst_transitions`

- The name "get_dst_transitions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Report whether a location observes daylight saving time, the next clock change, and every summer/winter-time transition (date, local time, and before/after offset) within a year. The result includes a source_url linking the matching worldclock.pro page when available.
```

### `search_cities`

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

Description, as the server wrote it:

```untrusted-server-text
Find cities by name (multilingual, diacritic-insensitive) — useful to resolve a place to a canonical slug, IANA timezone, and coordinates before calling the time tools. Each result includes a source_url linking the city's worldclock.pro page.
```

### `time_by_coordinates`

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

Description, as the server wrote it:

```untrusted-server-text
Resolve the timezone for a latitude/longitude coordinate (via geo-tz) and return the local time there.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__time__get_current_time",
      "mcp__time__time_by_coordinates",
      "mcp__time__get_dst_transitions",
      "mcp__time__search_cities"
    ],
    "ask": [
      "mcp__time__convert_time"
    ],
    "deny": []
  }
}
