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 → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- 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 880 tokens (~440/item across 2 items; 1 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 Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

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.

calculate_hours Calculate hours worked ~772
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.
