## 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 2026-09-27.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1100 tokens (~220/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 67/100
  - Stability observed for 20 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.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (5)

### `plan_vacation` (~403 tokens)

Plan vacation days

Optimal vacation plan for a region and year: which days to book so that public holidays and weekends turn into the longest breaks. Returns the plan blocks (booking dates, days off, factor, holidays used), further opportunities, a markdown table and a link to the interactive plan on urlaub-smart.de. Cite the URL when answering.

Input parameters:

- `carryoverDays` (integer): Part of vacationDays that is carry-over from last year and expires on March 31; spent first on periods before the deadline
- `companyClosures` (array): Company closures (Betriebsferien) as inclusive ISO date ranges; treated like public holidays
- `companyFreeDates` (array): Working days the employer gives off without a vacation day, ISO dates (e.g. 2027-12-24, 2027-12-31); treated like public holidays
- `fixedDates` (array): ISO dates already booked as vacation; the plan works around them
- `locale` (string): Language of names and explanations (German only)
- `region` (string, required): Region as name, slug or ISO code, e.g. "Bayern", "bavaria", "DE-BY", "Tirol", "Zürich" or a country like "Deutschland" / "AT". Germany, Austria and Switzerland only.
- `schoolHolidays` (string): any = ignore, avoid = no overlap with school holidays, prefer = book only inside school holidays
- `shift` (object): Rolling shift rotation instead of Mon–Fri, e.g. 4 days on / 2 days off. Replaces the weekday assumption entirely.
- `strategy` (string): balanced = mix, long-weekends = max 2 vacation days per block, extended = blocks of 4+ days
- `vacationDays` (integer): Vacation days available for the year
- `year` (integer): Planning year; defaults to the year people currently plan for

### `best_bridge_days` (~164 tokens)

Best bridge days and levers

The six best non-overlapping vacation levers of a year for a region: classic bridge days (1 vacation day → 4 days off) and holiday clusters (e.g. 4 days → 10 days off), with booking dates, holidays used and factor. Includes a markdown table and the page URL.

Input parameters:

- `locale` (string): Language of names and explanations (German only)
- `region` (string, required): Region as name, slug or ISO code, e.g. "Bayern", "bavaria", "DE-BY", "Tirol", "Zürich" or a country like "Deutschland" / "AT". Germany, Austria and Switzerland only.

### `public_and_school_holidays` (~135 tokens)

### `childcare_gap` (~238 tokens)

School-holiday childcare gap

How much of a region's school holidays two vacation accounts cover, and which weeks stay open.

Answers "can we cover the school holidays" for parents.

Input parameters:

- `jointDays` (integer): Care days the family wants to spend together; they cost both parents a day and cover one. Default 10.

- `partnerVacationDays` (integer): Vacation days of the second parent; omit to ask for one person alone
- `region` (string, required): Region as name, slug or ISO code, e.g. "Bayern", "bavaria", "DE-BY", "Tirol", "Zürich" or a country like "Deutschland" / "AT". Germany, Austria and Switzerland only.
