Available components
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 Security97
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. View diagnostics → Pass
- 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
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1301 tokens (~260/item across 5 items; 3 tools + 2 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 Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage93
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 79% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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
Unverified: 1 category
A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the VistaLink Hotels MCP server?
VistaLink Hotels is a hosted endpoint at https://api.vistalink.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
chat_about_hotels Chat about hotels ~349
Conversational hotel search for natural-language requests, comparisons and subjective preferences. Slower than search_hotels. Requires signing in (a linked Parley account) or an API key. Guest context (travel style, purpose, accessibility needs, loyalty programs, dietary needs) can be passed in the context parameter as a JSON object. Clarifications: if a previous response included a ``clarification_pending`` payload, show the question to the user and either pass ``clarification_id`` + ``clarification_option_id`` for the chosen option, or pass the user's free-text answer in ``message`` and leave the clarification params empty. Args: message: The user's message or question session_id: Session id from a previous response to continue the conversation (empty for a new session) currency: Currency code for prices (default EUR) context: JSON object with guest context (empty to skip). Example: {"travel_style": "luxury", "purpose": "honeymoon", "accessibility": "wheelchair", "loyalty_programs": ["Marriott Bonvoy"], "dietary": "vegetarian"} clarification_id: When replying to a prior clarification, the id from ``clarification_pending.clarification_id`` in that response. clarification_option_id: When replying to a prior clarification, the id of the option the user selected.
| Name | Type | Req | Description |
|---|---|---|---|
| clarification_id | string | – | – |
| clarification_option_id | string | – | – |
| context | string | – | – |
| currency | string | – | – |
| message | string | yes | – |
| session_id | string | – | – |

get_hotel_details Get hotel details ~218
Full profile of one hotel by its hotel_id from search_hotels: description, amenities, images, rooms, guest reviews and guest insights. A price is included only when both check_in and check_out are given, as the all-inclusive total for that stay. Works without an API key (cached prices only).
| Name | Type | Req | Description |
|---|---|---|---|
| check_in | string | – | Check-in date, YYYY-MM-DD (today or later). Prices need check_in and check_out. |
| check_out | string | – | Check-out date, YYYY-MM-DD, after check_in. |
| currency | string | – | ISO 4217 currency code for prices, e.g. 'EUR', 'USD', 'GBP'. |
| guests | integer | – | Number of adult guests (0 = default of 2). |
| hotel_id | string | yes | The hotel's id (a UUID), as returned in hotel_id by search_hotels. |
| rooms | integer | – | Number of rooms (0 = 1). Prices are only quoted for one room. |
No output schema declared.
No examples provided.
search_hotels Search hotels ~559
Search the VistaLink hotel catalogue in one city (or around a point). Needs city, latitude+longitude, or hotel_name; describe the stay in vibe. Returns hotels with ratings, location, amenities, images and guest-review insights. A price appears only when both check_in and check_out are given (the all-inclusive total for that stay). Works without an API key (at most 20 results, cached prices only). For open-ended questions use chat_about_hotels.
| Name | Type | Req | Description |
|---|---|---|---|

| check_in | string | – | Check-in date, YYYY-MM-DD (today or later). Prices need check_in and check_out. |
| check_out | string | – | Check-out date, YYYY-MM-DD, after check_in. |
| city | string | – | City to search in, e.g. 'Lisbon'. A search needs city, latitude+longitude, or hotel_name. |
| country | string | – | ISO 3166-1 alpha-2 country code of the city, e.g. 'PT'. Use it for city names that exist in several countries (Paris FR vs Paris US). |
