## 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 2026-11-05.

- **Endpoint Security**: 83/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - 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 715 tokens (~143/item across 5 items; 4 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 81/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 33% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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).
  - Supports UI / widget rendering.

## MCP tools (4)

### `resolve_destination` (~72 tokens)

Find destinations

Find the Guestit destination for a place name before searching stays. Pass the place alone, such as Åre or Stockholm. Returns only places with Guestit stays, at most one. When nothing matches, ask the user about a larger place nearby.

Input parameters:

- `locale` (string)
- `query` (string, required)

Output parameters:

- `applied_filters`
- `calculated_at` (string)
- `destinations` (array)
- `locale` (string)
- `pagination`
- `requested_stay`
- `stays` (array)
- `view` (string)

### `search_stays` (~324 tokens)

Search stays

Search public Guestit accommodation using a location_id from resolve_destination. Refine by resending the full filter set. Each stay is a short card; read house rules and the cancellation policy with stay_details or compare_stays before recommending one. Prices are estimates for the supplied dates and guests, with no inventory hold. Stays that fail the live check for those dates are left out, so a page can hold fewer than its limit. Nightly-rate filters use indexed average rates in SEK, not final stay totals. Pagination counts reflect the search index; current public rows may be fewer. Complete booking on the returned Guestit website link, which opens with the dates and guests filled in.

Input parameters:

- `end_date` (string): YYYY-MM-DD. Supply both dates. Check-in must be within 730 days and the stay cannot exceed 730 nights.
- `limit` (integer)
- `locale` (string)
- `location_id` (string, required)
- `min_bedrooms` (integer)
- `nightly_rate_max` (number): Maximum indexed average nightly rate in SEK. The final stay total includes the applicable fees.
- `nightly_rate_min` (number): Minimum indexed average nightly rate in SEK. This is not an all-in stay total.
- `num_guests` (integer, required)
- `page` (integer)
- `sort` (string)
- `start_date` (string): YYYY-MM-DD. Supply both dates. Check-in must be within 730 days and the stay cannot exceed 730 nights.
- `with_pets` (boolean)

Output parameters:

- `applied_filters`
- `calculated_at` (string)
- `destinations` (array)
- `locale` (string)
- `pagination`
- `requested_stay`
- `stays` (array)
- `view` (string)

### `stay_details` (~161 tokens)

Stay details

Read a public Guestit listing, house rules, cancellation policy and dated price estimate. Supply both dates and the guest count for an estimate. Fees shown are already included in the total. This does not reserve inventory or take payment. Open website_url to continue on Guestit; it opens with the dates and guests filled in.

Input parameters:

- `end_date` (string): YYYY-MM-DD. Supply both dates. Check-in must be within 730 days and the stay cannot exceed 730 nights.
- `listing_slug` (string, required)
- `locale` (string)
- `num_guests` (integer, required)
- `start_date` (string): YYYY-MM-DD. Supply both dates. Check-in must be within 730 days and the stay cannot exceed 730 nights.

Output parameters:

- `applied_filters`
- `calculated_at` (string)
- `destinations` (array)
- `locale` (string)
- `pagination`
- `requested_stay`
- `stays` (array)
- `view` (string)

### `compare_stays` (~136 tokens)

Compare stays

Compare two to four distinct Guestit listings for the same dates and number of guests. Retains missing or unavailable listings. Prices include applicable fees and do not hold inventory or confirm a booking.

Input parameters:

- `end_date` (string, required): YYYY-MM-DD. Supply both dates. Check-in must be within 730 days and the stay cannot exceed 730 nights.
- `listing_slugs` (array, required)

Output parameters:

- `applied_filters`
- `calculated_at` (string)
- `destinations` (array)
- `locale` (string)
- `pagination`
- `requested_stay`
- `stays` (array)
