## Findings

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

```untrusted-server-text
The server marks "find_meeting_slots" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "find_meeting_slots" says "find": a word for reading.
```

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

```untrusted-server-text
The server marks "business_days" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "count": a word for reading.
```


## Changes things (9)

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

### `business_days`

- The description's first verb is "count": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Count business days between two dates in a place, inclusive, with the calendar total and the weekend and holiday counts. It has NO holiday calendar: without holidays, only weekends are excluded.
```

### `contacts_set`

- The name "contacts_set" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save one person's zone and working hours so later calls can name them. Returns the resolved zone and their local time now. Saving the same name REPLACES that contact and says so. Free: 5 contacts.
```

### `convert_time`

- The name "convert_time" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Convert one time from from_zone into every zone in to_zones, marking any day change, plus the UTC instant. The time is wall-clock in from_zone unless it carries an offset or a trailing Z. '3pm tomorrow' works.
```

### `dst_changes`

- 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
The clock changes in a place for a year, with the exact UTC instant and the offset before and after. Use it to check whether a recurring call moves for one of you in March or October.
```

### `find_meeting_slots`

- The name "find_meeting_slots" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Rank the times when every participant is inside their own working hours. Returns each slot as a UTC instant with the local time for every participant and a fairness score, best first.
```

### `ics_create`

- The name "ics_create" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to write a .ics for one meeting and return the path plus the start in UTC and in your zone. Times are stored in UTC so it lands correctly in any client. Free: 3 files a month.
```

### `license_activate`

- 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
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
```

### `now`

- 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
The current time in one or more places, each with the zone it resolved to and the local date, time and offset, under one UTC instant. Accepts IANA zones, cities, countries and abbreviations.
```

### `overlap`

- 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
The window each day when every listed place is inside working hours. Computed on a real date, so a DST week that widens or narrows the overlap is reflected.
```

## Only reads (2)

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

### `contacts_list`

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

Description, as the server wrote it:

```untrusted-server-text
List saved contacts with their zone, local time now, working hours and whether they are inside them; weekends count as outside. It also prints YOUR zone from the shared business profile.
```

### `license_status`

- The name "license_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
```
