Schema Quality & AI Usability83
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 6199 tokens (~112/item across 55 items; 54 tools + 1 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

MCP tools — 54 exposed · ~5,974 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
update_calendar ~128

Update a calendar's name, timezone, agent status, default reminders, or metadata. Agent-scoped keys may only update calendars owned by their agent.

NameTypeReqDescription
agent_statusstringOwning agent's status
calendar_idstringyesCalendar ID to update
default_remindersDefault reminder offsets in minutes; null for system default, [] for none
metadataobjectArbitrary metadata (max 16KB)
namestringNew calendar name
timezonestringNew IANA timezone (e.g. America/New_York)

No output schema declared.

No examples provided.

update_event ~299

Reschedule or edit an event — change its title, description, start/end times, location, status, reminders, or metadata. Use this to move an appointment to a new time or update its details. Provide only the fields you want to change. Holds cannot be edited via this tool (use confirm_event / release_event). External iCal events are read-only. `calendar_id` is optional — if omitted it is resolved from the event.

NameTypeReqDescription
all_daybooleanWhether this is an all-day event
calendar_idstringCalendar ID that owns the event. Optional — if omitted the calendar is resolved from the event.
descriptionNew description, or null to clear it
end_timestringNew end time (ISO 8601)
event_idstringyesEvent ID to update
metadataobjectReplacement metadata object
recurrence_ruleSet/change the recurring series rule (RFC 5545 RRULE subset, full-series semantics), or null to make the event a one-off. Changing the rule or start_time resets cancelled occurrences.
remindersReminder offsets in minutes before start_time. Omit to leave unchanged, null to inherit the calendar default, [] for no reminders.
start_timestringNew start time (ISO 8601)
statusstringNew event status
titlestringNew event title

No output schema declared.
