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 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 Usability73
- 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 761 tokens (~152/item across 5 items; 4 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 Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage79
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 38% 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 4 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
How do I install the Staylist World MCP server?
Staylist World is a hosted endpoint at https://staylist.world/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.

No change was recorded against any check on this day. Stability & Change Management went from 17 to 27. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

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 →
get_booking_link Get hotel booking links ~164
Return the approved booking links for a hotel (the same links shown to people on staylist.world) plus the Staylist hotel page. Property links open the exact hotel on Trip.com or Klook, where the traveler picks dates and room; preserve these URLs unchanged. Dated offer links, when present, are sorted by total price. The traveler completes checkout on the booking site; this tool cannot book or charge anyone.
| Name | Type | Req | Description |
|---|---|---|---|
| adults | integer | – | – |
| checkin | string | – | Calendar date in YYYY-MM-DD format; provide both dates or neither |
| checkout | – | – | Calendar date in YYYY-MM-DD format; provide both dates or neither |
| children_ages | array | – | – |
| hotel_id | string | yes | Exact hotel id returned by search_hotels |
No output schema declared.
No examples provided.
get_hotel Hotel details and AI overview ~192
Hotel details: address, star class, amenities, Staylist's AI overview (a written summary with pros, cons and who the hotel suits, where one exists), how the hotel compares with others in its city, check-in/out times, child policy, nearest airport/station, and booking links. No photos: people see those on the booking page; for live-provider hotels also booking-site offers for the requested dates and guests (total, room, cancellation, conditions). refundable=null means unknown. Prices are not guaranteed. Preserve dates and occupancy from the search.
| Name | Type | Req | Description |
|---|---|---|---|
| adults | integer | – | – |
| checkin | string | – | Calendar date in YYYY-MM-DD format; provide both dates or neither |
| checkout | – | – | Calendar date in YYYY-MM-DD format; provide both dates or neither |
| children_ages | array | – | – |
| hotel_id | string | yes | Exact hotel id returned by search_hotels |
No output schema declared.
No examples provided.
list_destinations Browse popular destinations ~40
Popular starting points with country codes. Optional; this list does not restrict which destinations can be searched. No provider search quota is used with the live provider.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_hotels Search hotels ~351
Use when the user wants hotel recommendations or wants hotels compared. Returns up to 20 hotels compared on the same criteria, each with area, nearest station, amenities and price where known; empty fields mean unknown, not bad. shortlist_url is a page you can share with the user comparing the top results side by side. Find hotels by city, name or preferences (query words also match amenities, e.g. "pool", "breakfast"). Cities in Staylist's catalogue return hotels that each have an approved partner booking link (Trip.com, Klook), with a score (Staylist AI score, or the Trip.com guest rating where there is none; see sample_estimate.score_source), star class, amenities, check-in/out times and nearby transport where collected, pros and cons, and a sample_estimate (a previously observed nightly price, not a quote for the dates). Other cities use a live provider with indicative prices for an explicit stay. Supply both dates or neither. One room, 1–8 adults and up to 6 children. Use get_booking_link for the traveler's link. Never send names, email addresses or payment details.
| Name | Type | Req | Description |
