## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Supply Chain Security**: 23/100
  - Malware scan not yet available for this package.
  - Known CVEs were checked across the 96 of 96 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 96 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 3 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 83/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1613 tokens (~134/item across 12 items; 11 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### 2026-09-17 (score 49)

First indexed and scored.

## MCP tools (11)

### `license_status` (~54 tokens)

License status

Report this server's licence state: product, tier free or pro, licence id, expiry, the key source and the upgrade URL. No arguments, no network. Explains a free-tier refusal; license_activate installs a key.

### `license_activate` (~71 tokens)

Activate license

Activate a Pro key (MCPL1.xxx.yyy) from checkout: verified offline against a built-in public key, saved to your config file. A wrong, malformed or expired key is refused, unsaved. license_status reads it back.

Input parameters:

- `key` (string, required): License key from the checkout confirmation page

### `now` (~74 tokens)

Current time in zones

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.

Input parameters:

- `zones` (array): Places or IANA zones, e.g. ['Warsaw','New York','India']

### `convert_time` (~213 tokens)

Convert a time between zones

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.

Input parameters:

- `fold` (string): Which occurrence of a time that happens twice because the clocks went back. Default 'first'.
- `from_zone` (string, required): Place the time is given in, e.g. 'Warsaw' or 'Europe/Warsaw'
- `gap` (string): What to do with a time that does not exist because the clocks jumped forward: 'forward' takes the time after the jump, 'backward' the time before it. Without this, such a time is refused.
- `time` (string, required): '2026-09-10 15:00', '2026-09-10T15:00:00Z', '3pm tomorrow', 'now'
- `to_zones` (array, required): Places to convert into

### `overlap` (~117 tokens)

Daily working-hours overlap

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.

Input parameters:

- `date` (string): Date to compute on, YYYY-MM-DD, default today
- `work_end` (string): Local working day end, default 17:00
- `work_start` (string): Local working day start, default 09:00
- `zones` (array, required): Places, e.g. ['Warsaw','New York','Bangalore']

### `find_meeting_slots` (~303 tokens)

Find meeting slots

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.

Input parameters:

- `days` (integer): How many days ahead to search, default 5, at most 366. Free tier: a search longer than 5 days is shortened to 5, not refused
- `duration_minutes` (integer): Meeting length in minutes, default 60, at most 1440
- `earliest_date` (string): First date to consider, YYYY-MM-DD, default today
- `limit` (integer): How many slots to return, default 8. Slots are ranked by fairness: the score is the WORST participant's distance in hours from 13:00 local, so a slot that is 07:00 for one person never outranks one t…
- `participants` (array, required): Who has to attend. A zone is OPTIONAL per person: a saved contact supplies their own, and anyone left without one (you, typically) takes the timezone on your shared business profile, so never ask the…
- `recurring` (boolean): Pro: also report the weekly recurring times that work on every searched weekday

### `dst_changes` (~73 tokens)

Daylight-saving changes

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.

Input parameters:

- `year` (integer): Calendar year, default this year
- `zone` (string, required): Place or IANA zone

### `business_days` (~159 tokens)

Count business days

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.

Input parameters:

- `from` (string, required): Start date, YYYY-MM-DD (inclusive). A date that does not exist, such as 2026-02-30, is refused, never rolled forward
- `holidays` (array): Dates to exclude, strict YYYY-MM-DD. This tool has no national holiday calendar: unless you pass holidays here only weekends are excluded, so do not report the answer as a public-holiday-adjusted cou…
- `to` (string, required): End date, YYYY-MM-DD (inclusive)
- `zone` (string, required): Place whose calendar to use

### `contacts_set` (~107 tokens)

Save a contact's zone

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.

Input parameters:

- `name` (string, required): Their name
- `work_end` (string): Local day end, default 17:00
- `work_start` (string): Local day start, default 09:00
- `zone` (string, required): Their place or IANA zone

### `contacts_list` (~44 tokens)

List saved contacts

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.

### `ics_create` (~380 tokens)

Write a calendar invite

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.

Input parameters:

- `attendees` (array): Attendees. An entry with an email is invited (ATTENDEE:mailto:...); a name with no email is listed in the description instead, because a calendar cannot invite a name.
- `description` (string): Body text
- `duration_minutes` (integer, required): Length in minutes, at most 1440
- `fold` (string): Which occurrence of a time that happens twice because the clocks went back. Default 'first'.
- `gap` (string): What to do with a time that does not exist because the clocks jumped forward: 'forward' takes the time after the jump, 'backward' the time before it. Without this, such a time is refused.
- `location` (string): Where, or a meeting link
- `organizer_email` (string): Your email address, written as the ORGANIZER so replies have somewhere to go. Leave it out and your shared business profile's email is used; with neither, the ORGANIZER line is omitted rather than fi…
- `organizer_name` (string): Your display name for the ORGANIZER line
- `out_path` (string): Where to write the .ics file; default meeting.ics in the data dir. Times are stored in UTC, so the invite lands at the right local time in every attendee's calendar with no time zone block to go stale
- `start` (string, required): Start time, read in `zone` unless it carries an offset
- `title` (string, required): Event title
- `zone` (string, required): Place the start time is given in
