## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-08-03.

- **Endpoint Security**: 60/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1231 tokens (~153/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 84/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 53% of tool parameters carry a description.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-02 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-31 (score 61, +2)

## MCP tools (8)

### `find_common_slots` (~230 tokens)

Rank the best meeting times for the given participants, merging live Google/Microsoft calendar data, hand-marked availability and the heat-map sources. Each participant is filtered (Mon–Fri, waking hours) and scored in their OWN timezone; scores factor in buffer time around existing meetings and prefer sooner slots. Returns up to 8 slots: everyone-free slots first (allFree:true), then — only if there are too few — the best compromise slots (allFree:false) with a freeCount. Defaults to the next 14 days. Requires authentication.

Input parameters:

- `durationMin` (number): Meeting length. Default 30.
- `from` (number): Window start, unix ms. Default: now.
- `participants` (array, required): Participant emails (the authenticated user is the host and should be included).
- `to` (number): Window end, unix ms. Default: now + 14 days.
- `tz` (string): Requester IANA zone, e.g. Europe/Warsaw — the fallback zone for participants whose own timezone is unknown, and the zone for the round-hour scoring bonus.

### `create_meeting` (~115 tokens)

Confirm a meeting: writes the event into the authenticated host’s calendar with an optional Google Meet/Teams link, emails invites with an ICS attachment, and returns the share URL (/m/<id>). Requires authentication.

Input parameters:

- `conference` (string): Omit for no conference link.
- `endsAt` (number, required): unix ms
- `participants` (array, required)
- `startsAt` (number, required): unix ms
- `title` (string)
- `tz` (string): IANA zone used to format times in invite emails.

### `get_meeting` (~52 tokens)

Read a meeting by its share-link id (the UUID from /m/<id>): time, title, conference URL, host, and any proposed alternate times with their status.

Input parameters:

- `meetingId` (string, required)

### `get_meeting_availability` (~137 tokens)

Aggregated group availability for an existing meeting (the symmetric heat-map): per-30-min-slot counts of how many participants are free, plus ranked slots (per-participant timezones, buffer + soonness scoring, allFree:true everyone-free slots and allFree:false compromise slots). Individual calendars are never exposed. No auth needed — the meeting id is the capability.

Input parameters:

- `durationMin` (number)
- `from` (number): unix ms. Default: now.
- `meetingId` (string, required)
- `to` (number): unix ms. Default: now + 14 days.
- `tz` (string)

### `suggest_time` (~158 tokens)

Propose a different time for an existing meeting on behalf of a guest. The host is notified by email and can accept or decline. Authenticated callers (Bearer PAT) skip the bot challenge; an anonymous caller must pass a Cloudflare Turnstile token in `turnstileToken` (only required when the server is configured with a Turnstile secret).

Input parameters:

- `endsAt` (number, required): unix ms
- `meetingId` (string, required)
- `message` (string)
- `startsAt` (number, required): unix ms
- `suggestedBy` (string, required): Email of the person proposing.
- `turnstileToken` (string): Cloudflare Turnstile token; required for anonymous callers when a Turnstile secret is configured.

### `respond_to_suggestion` (~68 tokens)

Accept or decline a proposed alternate time. Accepting moves the meeting (calendar event included) and re-sends invites. Only the meeting host may call this — requires authentication.

Input parameters:

- `action` (string, required)
- `meetingId` (string, required)
- `suggestionId` (string, required)

### `set_manual_availability` (~161 tokens)

Publish hand-marked FREE time slots for an email address (the no-calendar fallback, e.g. Apple iCloud users). Replaces previously marked slots inside the window; the group heat-map updates immediately. Authenticated callers (Bearer PAT) skip the bot challenge; an anonymous caller must pass a Cloudflare Turnstile token in `turnstileToken` (only required when the server is configured with a Turnstile secret).

Input parameters:

- `email` (string, required)
- `freeSlots` (array, required)
- `turnstileToken` (string): Cloudflare Turnstile token; required for anonymous callers when a Turnstile secret is configured.
- `windowFrom` (number, required): unix ms
- `windowTo` (number, required): unix ms

### `get_manual_availability` (~45 tokens)

Read previously hand-marked free slots for an email within a window.

Input parameters:

- `email` (string, required)
- `from` (number, required)
- `to` (number, required)
