No check matched anything in these tool definitions.


## Changes things (2)

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

### `calculate_schengen_days`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user needs a schengen calculator, schengen days left, schengen overstay dates or a 90/180 rule calculator for past and planned short stays. Returns days used and left on the check date, stay compliance, overstay dates and daily CSV. Accepts ISO or English US text dates, up to 60 stays over 1,100 days, years 1900–2100. Open stays end at the check date; touching stays merge. Does not model bilateral agreements, residence permits, long-stay visas or visa-sticker limits; calculation aid, not legal advice.
```

### `plan_schengen_trip`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks how many days can I stay in Europe, wants a schengen visa calculator or needs to plan 90 days in 180 days. Finds the maximum consecutive short stay from an entry date and the first entry that supports a requested length. Past stays must be closed and end by entry; up to 60 stays over 1,100 days, years 1900–2100, requested lengths 1–90 days. Does not authorize entry or model bilateral agreements, residence permits, long-stay visas or visa-sticker limits; not legal advice.
```

## Only reads (1)

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

### `find_schengen_reset_dates`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants schengen days left to return, a schengen 90 day rule projection or a days in Europe calculator for future availability. Projects window headroom on the next 180 dates with a daily CSV, assuming no further stays and departure by the reference date. Up to 60 stays over 1,100 days, years 1900–2100. Reference date defaults to America/New_York today. Headroom is not maximum consecutive trip length. Does not model bilateral agreements, residence permits, long-stay visas or visa-sticker limits; not legal advice.
```
