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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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 Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1256 tokens (~157/item across 8 items; 8 tools + 0 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage88
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 64% 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
How do I install the app.g-guest/g-guest MCP server?
app.g-guest/g-guest is a hosted endpoint at https://g-guest.app/api/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 →
cancel_booking ~171
Cancel an upcoming booking and release its slot to other guests. Identified like check_booking: booking_id plus manage_token. Confirm with the guest before calling; the cancellation is immediate and this server cannot undo it, the guest would simply book again. The venue is notified exactly as for a cancellation from the manage link. Safe to retry: cancelling a booking that is already cancelled returns the same result, not an error. A booking whose start time has passed cannot be cancelled and returns an error saying so. To move a booking to another time, cancel it and create a new one.
| Name | Type | Req | Description |
|---|---|---|---|
| booking_id | string | yes | The booking_id create_booking returned, or the id in the guest's manage link. |
| manage_token | string | yes | The token from the same booking's manage link (its ?token= parameter). |
No output schema declared.
No examples provided.
check_availability ~67
List bookable time slots for a business on a given date and party size. Offer the guest only slots where available is true.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | yes | YYYY-MM-DD, in the venue's local calendar. |
| party_size | integer | yes | – |
| slug | string | yes | – |
No output schema declared.
No examples provided.
check_booking ~195
Look up one existing booking so the guest can confirm when and where it is. Identify it with the booking_id and manage_token that create_booking returned; both also sit in the guest's confirmation email as the manage link, /booking/<booking_id>?token=<manage_token>. Returns the business, the local date and time with its timezone, party size, service and status: confirmed, pending_confirmation, pending_payment (with payment_url while it can be paid), cancelled, or for past bookings completed or no_show. Never returns the guest's name, email or phone. A wrong or missing token is refused without revealing whether the booking exists.
| Name | Type | Req | Description |
|---|---|---|---|
| booking_id | string | yes | The booking_id create_booking returned, or the id in the guest's manage link. |
| manage_token | string | yes | The token from the same booking's manage link. If the guest only has the link, take the token from its ?token= parameter. |
No output schema declared.
No examples provided.
create_booking ~277
Create a real reservation. Use a start value returned by check_availability. Never invent guest details. Ask the person for their real name, email and phone first. If the result status is pending_confirmation, show the guest the confirmation_url. If it is pending_payment, the venue takes a prepayment: show the guest the payment_url, and do not say it is booked until it is paid.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | – | |
| idempotency_key | string | – | Retry safety: pick any unique string for this booking attempt and reuse it on retries. The same key always returns the same booking, never a duplicate. |
| language | string | – | The guest's language as an ISO 639-1 code: en, nl, de, fr, es, it, id or bg. The confirmation, the reminders and the manage page are sent in it. Defaults to English. |
| name | string | yes | – |
| notes | string | – | – |
| party_size | integer | yes | – |
| phone | string | yes | – |
| slug | string | yes | – |
| source | string | – | Which assistant is booking. Defaults to other_ai. proof_video is our own channel: bookings made while filming a proof clip. |
| start | string | yes | The slot's `start` value, copied exactly as check_availability returned it. |
No output schema declared.
No examples provided.
fetch ~36
Fetch full details for one business id returned by search: services, hours, timezone and how to book it.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | – |
No output schema declared.
No examples provided.
get_business ~53
Look up a business on G-Guest: services, opening hours, timezone and maximum party size. Call this first if you only know the slug.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Business identifier, e.g. "demo". |
No output schema declared.
No examples provided.
request_listing ~306
Ask G-Guest to list a business that is not on it yet. Use it when the person you are helping runs a restaurant, cafe, bar, salon, spa, studio or clinic and wants reservations that assistants can make. Nothing is published by this call: the request reaches the G-Guest team as a lead, a person reviews it and contacts the business, and only then is anything set up. The owner's or manager's email is required, because the reply comes by email; a phone is optional extra. Do not call it for a guest who merely wants to book somewhere, and never submit a business without its owner's or manager's say-so. Returns a receipt with a reference id; no timeline is promised.
| Name | Type | Req | Description |
|---|---|---|---|
| business_name | string | yes | The business's own name, as its owner writes it. |
| business_type | string | yes | The closest category. |
| city | string | yes | City and country, e.g. "Canggu, Indonesia". |
| contact_email | string | yes | Email of the owner or manager who asked. The reply goes here. |
| contact_name | string | – | Who asked, so the reply can address them by name. |
| contact_phone | string | – | Phone with country code, optional. |
| message | string | – | Anything the owner wants the team to know: languages, seats, how bookings are taken today. Up to 500 characters. |
| website | string | – | The business website or Instagram page, if it has one. |
No output schema declared.
No examples provided.
search ~40
Search bookable businesses on G-Guest by name or slug. Returns ids you can pass to fetch or to the booking tools.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | – |
No output schema declared.
