## 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 2026-10-23.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - 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 880 tokens (~440/item across 2 items; 1 tools + 1 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.
  - Supports UI / widget rendering.

### `calculate_hours` (~772 tokens)

Calculate hours worked

Use this when the user wants a time card calculator or hours worked calculator: totaling clock-in/clock-out times for a day, week, or biweekly period, with lunch breaks, multiple in and out punches per day, overnight shifts, 12-hour or 24-hour (military) time, punch rounding (nearest 5/6/15 minutes or the 7-minute rule), overtime and double time per workweek (US federal 40 h, California daily rules, or custom), and gross pay from an hourly rate. Pass times as the user wrote them; times without am/pm ("9 to 5") are resolved and the reading is returned in assumptions for the user to confirm. Returns per-day hours in H:MM and decimal, regular/overtime/double-time split, totals, exact gross pay, warnings (overlapping punches, missing clock-out, shifts over 16 h), and CSV and printable PDF timesheet links. Does not compute taxes or take-home pay, give legal advice about breaks or overtime, track time live, or set reminders. Do not use for simple unit conversions without clock times.

Input parameters:

- `currency` (string): ISO currency code for pay amounts, default USD, e.g. EUR or GBP.
- `daily_double_time_after_hours` (number): Override the daily double-time threshold in hours, e.g. 12. 0 turns double time off.
- `daily_overtime_after_hours` (number): Override the daily overtime threshold in hours, e.g. 8 (Alaska, Nevada) or 12 (Colorado). 0 turns daily overtime off.
- `double_time_multiplier` (number): Double-time pay multiplier, default 2.
- `entries` (array, required): One item per worked day (up to 62, e.g. a biweekly or monthly time card). Example: [{"day":"Mon","punches":[{"start":"8:45","end":"17:30"}],"unpaid_break_minutes":30}].
- `hourly_rate` (number): Optional regular hourly pay rate in the chosen currency for gross pay, e.g. 18.50 (USD) or 1100 (JPY). Leave out for hours only.
- `overtime_multiplier` (number): Overtime pay multiplier, default 1.5.
- `overtime_preset` (string): Overtime rule set. us_federal (default): over 40 h per workweek at 1.5x. california: over 8 h/day and 40 h/week at 1.5x, over 12 h/day at 2x, plus the 7th-consecutive-day rule. none: no overtime spli…
- `pay_period` (string): Optional pay period label printed on the timesheet, e.g. "Sep 28 - Oct 11, 2026" or "Week 40".
- `rounding` (string): Punch rounding applied to each clock-in and clock-out: none (default), nearest_5, nearest_6 (tenth of an hour), nearest_15, or seven_minute_rule (8:07 -> 8:00, 8:08 -> 8:15).
- `seventh_day_rule` (boolean): California 7th-consecutive-day rule: on the 7th straight workday of a workweek the first 8 h are overtime and the rest double time. Default on for california, off otherwise.
- `week_start_day` (string): First day of the workweek for dated entries, e.g. "sun". Default: the weekday of the earliest date.
- `weekly_overtime_after_hours` (number): Override the weekly overtime threshold in hours, e.g. 40 or 37.5. 0 turns weekly overtime off.

Output parameters:

- `assumptions` (array): Readings of ambiguous clock times (no am/pm) that the user should confirm; empty when none.
- `days` (array)
- `downloads` (object)
- `note` (string)
- `pay`
- `pay_period` (string|null)
- `settings` (object)
- `totals` (object)
- `warnings` (array)
- `weeks` (array)
