Trust breakdown (6 categories)

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. How we score →

Endpoint Security60

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
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. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability69

AI-judged instruction clarity (excellent).Pass
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. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage84

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
53% of tool parameters carry a description.Partial

Capabilities40

Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail

MCP tools — 8 exposed · ~966 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

create_meeting ~115

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 Output Examples

Name	Type	Req	Description
conference	string	—	Omit for no conference link.
endsAt	number	yes	unix ms
participants	array	yes	—
startsAt	number	yes	unix ms
title	string	—	—
tz	string	—	IANA zone used to format times in invite emails.

No output schema declared.

No examples provided.

find_common_slots ~230

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 Output Examples

Name	Type	Req	Description
durationMin	number	—	Meeting length. Default 30.
from	number	—	Window start, unix ms. Default: now.
participants	array	yes	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.

No output schema declared.

No examples provided.

get_manual_availability ~45

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

Input Output Examples

Name	Type	Req	Description
email	string	yes	—
from	number	yes	—
to	number	yes	—

No output schema declared.

No examples provided.

get_meeting ~52

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 Output Examples

Name	Type	Req	Description
meetingId	string	yes	—

No output schema declared.

No examples provided.

get_meeting_availability ~137

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 Output Examples

Name	Type	Req	Description
durationMin	number	—	—
from	number	—	unix ms. Default: now.
meetingId	string	yes	—
to	number	—	unix ms. Default: now + 14 days.
tz	string	—	—

No output schema declared.

No examples provided.

respond_to_suggestion ~68

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 Output Examples

Name	Type	Req	Description
action	string	yes	—
meetingId	string	yes	—
suggestionId	string	yes	—

No output schema declared.

No examples provided.

set_manual_availability ~161

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 Output Examples

Name	Type	Req	Description
email	string	yes	—
freeSlots	array	yes	—
turnstileToken	string	—	Cloudflare Turnstile token; required for anonymous callers when a Turnstile secret is configured.
windowFrom	number	yes	unix ms
windowTo	number	yes	unix ms

No output schema declared.

No examples provided.

suggest_time ~158

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 Output Examples

Name	Type	Req	Description
endsAt	number	yes	unix ms
meetingId	string	yes	—
message	string	—	—
startsAt	number	yes	unix ms
suggestedBy	string	yes	Email of the person proposing.
turnstileToken	string	—	Cloudflare Turnstile token; required for anonymous callers when a Turnstile secret is configured.

No output schema declared.

No examples provided.
