## 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 2026-09-20.

- **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 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1225 tokens (~94/item across 13 items; 12 tools + 1 resources), lean.
  - 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**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "ics_forget" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 13 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.

First indexed and scored.

## MCP tools (12)

### `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

### `ics_import` (~143 tokens)

Import a calendar (.ics)

Call this tool to read a calendar export and keep it under a name. Give path (.ics file), text (contents), or url (public .ics/webcal feed; Pro). Google, Apple, Outlook exports read. Re-importing a name replaces it.

Input parameters:

- `name` (string, required): What to call this calendar, e.g. "work" or "family"
- `path` (string): Path to a .ics file on this machine
- `text` (string): The .ics file contents, pasted
- `url` (string): Public https:// or webcal:// .ics feed. Fetched once, only because you asked; Pro feature

### `calendars_list` (~54 tokens)

List imported calendars

List imported calendars: name, event-definition count, size, source, import time and free-tier use of the 2 slots. It also names stored .ics files with no calendar row. With none it prints the export steps.

### `events_list` (~115 tokens)

List events in a window

Every event between two dates, recurring expanded to occurrences, sorted by start. Times shown in your zone (profile's, else this machine's) unless zone passed. Each id works for event_export or event_to_time_entry.

Input parameters:

- `calendar` (string): One calendar name; default every imported calendar
- `from` (string, required): First day, YYYY-MM-DD
- `to` (string, required): Last day, YYYY-MM-DD, included
- `zone` (string): Show local times in this zone or city instead of your own

### `events_search` (~94 tokens)

Search events

Find events whose title, description, location or attendees contain a phrase. Searches every imported calendar. Without from/to it looks a year back and a year forward on Pro, and the free window either side of today.

Input parameters:

- `from` (string): First day, YYYY-MM-DD
- `query` (string, required): Words to look for, case-insensitive
- `to` (string): Last day, YYYY-MM-DD, included

### `free_busy` (~159 tokens)

Busy blocks and free windows

Merged busy blocks and the free gaps inside your working hours over a day range. Events marked free do not count; whole-day events block the day. Free: 31 days. Use conflicts for overlapping pairs.

Input parameters:

- `calendars` (array): Calendar names; default all of them
- `from` (string, required): First day, YYYY-MM-DD
- `to` (string, required): Last day, YYYY-MM-DD, included
- `work_end` (string): End of your working day, HH:MM, default 17:00
- `work_start` (string): Start of your working day, HH:MM, default 09:00
- `zone` (string): Zone the working hours and the output are in; default your own

### `conflicts` (~95 tokens)

Find double bookings

Find double bookings: every PAIR of timed events that overlap, with the minutes they collide, across all calendars unless you name one. Whole-day events are reported apart. Free: 31 days. free_busy shows gaps.

Input parameters:

- `calendar` (string): One calendar name; default every imported calendar
- `from` (string, required): First day, YYYY-MM-DD
- `to` (string, required): Last day, YYYY-MM-DD, included

### `next_event` (~67 tokens)

Next event

The first event not yet started, within the next 366 days, across every imported calendar or one you name. Returns title, times in your zone, how long until it starts, location, attendees and its id.

Input parameters:

- `calendar` (string): One calendar name; default every imported calendar

### `event_export` (~136 tokens)

Export events to a .ics file

Call this tool to write chosen events to a new .ics file you can send or import elsewhere. Pass either ids (from events_list) or a from/to window. Times are written in UTC so the file lands correctly in any client.

Input parameters:

- `calendar` (string): With from/to: limit to one calendar
- `from` (string): First day, YYYY-MM-DD (alternative to ids)
- `ids` (array): Event ids from events_list, events_search or next_event
- `out_path` (string, required): Where to write the .ics file
- `to` (string): Last day, YYYY-MM-DD, included

### `event_to_time_entry` (~155 tokens)

Turn a meeting into a time entry

Take one event and return the exact arguments for the time-tracker's entry_add, so a meeting that already happened becomes billable time without retyping it. Writes nothing: pass the JSON straight to entry_add.

Input parameters:

- `currency` (string): Currency of the rate: EUR, USD, GBP, PLN, or the word the user said ('euros'). Without it the time-tracker falls back to USD.
- `event_id` (string, required): Event id from events_list, events_search or next_event
- `project` (string, required): Project or client the meeting is billed to
- `rate`: Hourly rate for this entry; a number (120) or the words the user said ('120 euros an hour')

### `ics_forget` (~64 tokens)

Forget a calendar

Remove one imported calendar by name and delete this server's local copy of its .ics, freeing a slot. Your own calendar and the source file are untouched. ics_import replaces a name in place.

Input parameters:

- `name` (string, required): The calendar name from calendars_list
