## 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 2026-10-25.

- **Endpoint Security**: 78/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 77/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2761 tokens (~184/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (15)

### `scheduleit_list_events` (~418 tokens)

List events

List scheduled events and tasks (bookings, shifts, jobs). Without date_from/date_to Schedule It uses its default date range. Schedule It returns only a short summary of each event unless you name the fields you want: pass `fields` such as id,title,date_start,date_end,owner,notes,completed,priority,custom1 (get_event returns ALL fields of one event). `owner` holds the ids of the resources (people, rooms, equipment) the event is linked to. There is no paging: the reply holds up to `limit` events (default 100), so narrow with the filters instead. Do not call this repeatedly to watch for changes (use modified_after to fetch only what changed). GET /api/events.

Input parameters:

- `date_from` (string): Events from this date (date_range_from).
- `date_to` (string): Events up to this date (date_range_to).
- `event_ids` (array): Only these event ids.
- `fields` (string): Comma-separated fields to return, e.g. id,title,date_start,date_end,owner.
- `limit` (integer): Most events to return, 1-1000 (default 100).
- `modified_after` (string): Only events added or changed after this date (yyyy-mm-dd) or date and time (yyyy-mm-dd hh:mm).
- `no_date_only` (boolean): true = only events with no date, false = only dated ones.
- `resource_ids` (array): Only events linked to these resources (see resource_match).
- `resource_match` (string): With resource_ids: any = linked to at least one (default), all = linked to every one, none = linked to none of them.
- `tasks_only` (boolean): true = only tasks, false = only events that are not tasks.
- `title` (string): Events whose title contains this text.
- `workspace_id` (integer): Workspace id (Account Settings > Workspaces). Omit for the main workspace (id 1).

### `scheduleit_get_event` (~56 tokens)

### `scheduleit_create_event` (~275 tokens)

Create event

WRITE: create a new event (booking, shift, job or task) in the Schedule It account, optionally linked to resources. It becomes visible to everyone with access to the schedule, and Schedule It may notify the linked resources according to the account's own notification settings. Confirm the title, dates and resources with the user first. POST /api/events.
