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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0

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 →
create_game_plan Create a shareable padel game plan ~96
Use this only when the user explicitly wants to organise one to three selected court options with other people. Rechecks each selected slot, creates an expiring Zarvo plan, and returns separate guest and private organiser links. This changes Zarvo state but does not book a court.
| Name | Type | Req | Description |
|---|---|---|---|
| age_confirmed | boolean | – | – |
| mode | string | yes | – |
| original_request | string | yes | – |
| slot_ids | array | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_availability Get club availability ~234
Use this when the user has selected a named provider club and wants its available courts on one date or across a bounded date range. Copy provider and club_name exactly from the selected search_clubs result; never infer provider from the club name. Results include Zarvo club IDs when matched and the total limit applies across all dates. number_of_players affects per-player price only; use singles_court to require explicit singles support. Do not use for a broad nearby search; use search_courts instead.
| Name | Type | Req | Description |
|---|---|---|---|
| club_name | string | yes | – |
| date | string | – | – |
| date_range | object | – | – |
| duration_minutes | integer | – | Omit to return every duration offered by the provider. |
| earliest_time | string | – | – |
| latest_end_time | string | – | – |
| limit | integer | – | – |
| number_of_players | integer | – | Used to compute per-player price only. Does not filter court capacity; use singles_court for that. |
| provider | string | yes | – |
| singles_court | boolean | – | When true, restrict results to courts or venues explicitly identified as supporting singles play. |
| Name | Type | Req | Description |
|---|---|---|---|
| data | array | yes | – |
| meta | object | yes | – |
No examples provided.
get_booking_handoff Get a provider booking handoff ~94
Use this directly after the user chooses a slot. It revalidates the provider slot and returns status unavailable with a reason if the slot was taken, or status available with a provider handoff URL and current price. The user completes login, booking, and payment on the provider site; Zarvo does not reserve inventory or complete checkout.
| Name | Type | Req | Description |
|---|---|---|---|
| number_of_players | integer | – | – |
| slot_id | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
get_club Get a padel club ~60
Use this after a Zarvo club ID is known and the user wants its address, coordinates, facilities, racket rental, contact information, official website, or social links. This returns directory metadata, not live availability.
| Name | Type | Req | Description |
|---|---|---|---|
| club_id | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| checked_at | string | yes | – |
| data | object | yes | – |
| snapshot_at | – | yes | – |
| source | object | yes | – |
No examples provided.
recheck_slot Recheck a selected court slot ~101
Optional standalone check. get_booking_handoff already revalidates before returning a URL; call this only to confirm availability without proceeding to handoff. It never books, holds inventory, takes payment, or returns checkout.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | – |
| duration_minutes | integer | – | – |
| earliest_time | string | – | – |
| latest_end_time | string | – | – |
| number_of_players | integer | – | – |
| slot_id | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
search_activities Search padel activities and coaching ~146
Use this when a player wants scheduled PadelStars activities such as coaching, training, intro sessions, socials, junior sessions, or competitions. Returns live session times, levels, vacancies, prices when published, and the provider booking page. It never joins, books, or pays on the user’s behalf.
| Name | Type | Req | Description |
|---|---|---|---|
| availability | string | – | – |
| category | string | – | – |
| earliest_time | string | – | – |

| start_date | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| data | array | yes | – |
| meta | object | yes | – |
No examples provided.
search_clubs Search padel clubs ~250
Use this lightweight directory lookup to find clubs by location and facilities or resolve a club description, nearby landmark, or partial club name into candidate club_id, club_name, and provider values. Put only club-name wording in query; add location when an area was supplied. Use court_type for indoor/outdoor/covered courts, racket_rental for racket hire, and facility for a requested amenity. Preserve these filters when refining a search. Do not infer or pass provider from a club or brand-like name: provider is only an explicit booking-platform hint. If that hint conflicts with the directory, name resolution may return the canonical provider instead. It returns Zarvo club metadata, not live court availability. Follow with get_club for full metadata or get_availability for live slots at a selected provider club.
| Name | Type | Req | Description |
|---|---|---|---|
| court_type | string | – | – |
| facility | string | – | – |
| limit | integer | – | – |
| location | string | – | – |
| provider | string | – | Only filter by provider when the user explicitly names a booking platform. Never infer this from the club name. |

search_courts Search available padel courts ~326
Use this when a group wants bookable court options near a UK location on one date or across a bounded date range. Searches configured providers, normalizes known whole-court and per-player prices, adds catalogue venue IDs and coordinates, and returns at most the requested limit across all dates. Providers such as MATCHi may return a null anonymous price; those slots remain visible under a price ceiling with price_details.basis unknown and must not be presented as budget matches. Travel time is a straight-line heuristic with a 15% soft-filter tolerance near max_travel_minutes, not live routing. number_of_players affects per-player price only; use singles_court to require explicit singles support. Do not use for venue-only discovery or public games.
| Name | Type | Req | Description |
|---|---|---|---|
| court_type | string | – | – |
| date | string | – | – |
| date_range | object | – | – |
| duration_minutes | integer | – | Omit to return every duration offered by the provider. |

| location | string | yes | – |
| max_price_per_player | number | – | – |
| max_travel_minutes | integer | – | – |
| number_of_players | integer | – | Used to compute per-player price only. Does not filter court capacity; use singles_court for that. |
| provider | string | – | – |
| radius_km | number | – | – |
| singles_court | boolean | – | When true, restrict results to courts or venues explicitly identified as supporting singles play. |

| Name | Type | Req | Description |
|---|---|---|---|
| data | array | yes | – |
| meta | object | yes | – |
No examples provided.
search_public_games Search public padel games ~154
Use this when a player wants an existing public padel game with an open spot. Omit date, time, level, and limit filters unless the user requested them; by default it returns every matching game around the location across the next 14 UK days. Returns anonymous match metadata and the provider join page; it never reveals player identities or joins on the user’s behalf. Do not use for empty-court bookings.
| Name | Type | Req | Description |

| date_range | object | – | – |
| earliest_time | string | – | – |

What is the Zarvo MCP server?
Zarvo is an MCP server listed in the public MCP registry as uk.zarvo/padel. Find UK padel courts, live availability and public games, then hand booking to the provider. This page covers its hosted endpoint (https://zarvo.uk/mcp).
Is the Zarvo MCP server safe to use?
Zarvo scores 33 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Zarvo MCP server expose?
Zarvo exposes 9 tools: search_courts, search_clubs, search_public_games, search_activities, get_club, and 4 more. Their descriptions and schemas cost roughly 1,461 tokens of context every time the server is loaded.
Does the Zarvo MCP server require authentication?
Yes. Zarvo asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the Zarvo MCP server still maintained?
Zarvo is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
