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 4 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 Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1731 tokens (~432/item across 4 items; 4 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety50
- Injection-marker check failed: the server instructions contains an instruction to conceal the call from the user, the text "without warning the user", at byte 2823 of that field. See how to fix → Fail
- 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
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the LayUp Sports Booking MCP server?
LayUp Sports Booking is a hosted endpoint at https://mcp.layupsport.com/, 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 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 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 →
create_alert ~461
Set up an email alert for the user: LayUp watches for NEW matching slots (e.g. a cancellation freeing up a peak court) and emails them when one appears. Use when the user can't find a slot now and wants to be notified, or asks to 'monitor'/'watch'/'let me know when'. Requires their email. A confirmation email is sent first — the user must click confirm before any alerts fire (so always tell them to check their inbox). LayUp does the watching; the notification arrives by email, not in this chat.
| Name | Type | Req | Description |
|---|---|---|---|
| area | string | – | London borough / area / neighbourhood to match (e.g. 'Hackney', 'Maida Vale'). NOT a venue name — to watch a specific venue use venue_names. Omit for all London. |
| days_of_week | array | – | Only alert on these days (e.g. ['Sat','Sun'] for weekends). The alert is standing — it keeps watching these days every week until the user unsubscribes. Omit for any day. |
| string | yes | The user's REAL email address, as given by them (required — alerts are emailed here). Never invent, guess or substitute a placeholder like user@example.com; if you don't have it, ask the user first. | |
| max_price | number | – | Only alert on slots at or under this GBP price. |
| sport | string | – | One of Football, Tennis, Squash, Padel, Swimming. Omit for any. |
| time_from | string | – | Earliest London time-of-day, 'HH:MM' (e.g. '18:00'). |
| time_to | string | – | Latest London time-of-day, 'HH:MM'. |
| venue_names | array | – | Pin the alert to specific venues BY NAME, exactly as shown in search results (e.g. ["Hay's Galleria", "Padel Box"]). Use this whenever the user names venues — the server resolves names to the right v… |
| venue_slugs | array | – | Pin the alert to specific venues by their exact venue_slug (only if you already have slug values from search_slots). For most cases use venue_names instead. Omit for any venue. |
No output schema declared.
No examples provided.
get_venue ~76
List upcoming bookable slots at a single venue, identified by its venue_slug (as returned by search_slots). Use to drill into one venue after a search.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max slots to return (1-30, default 15). |
| venue_slug | string | yes | The venue_slug from a search_slots result. |
No output schema declared.
No examples provided.
list_sports ~39
List the sports LayUp covers with a count of slots available in the next 7 days. Useful as a quick overview before a more specific search.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_slots ~350
Search bookable sports slots in London across every provider LayUp aggregates. Use when a user wants to find a court, pitch, lane, class or pickup game for football, tennis, squash, padel or swimming. Filter by sport, area/borough, date range, time of day and max price. Returns upcoming slots with venue, London-local time, price, provider and a booking link. Times default to the next 7 days.
| Name | Type | Req | Description |
|---|---|---|---|
| area | string | – | London borough, area or venue name to match (e.g. 'Hackney', 'Southwark', 'Clissold'). |
| booking_type | string | – | 'spot' = book one place (pickup game / swim seat), 'court' = whole court, 'pitch' = whole pitch. |
| date_from | string | – | ISO date or datetime — earliest start. Defaults to now. |
| date_to | string | – | ISO date or datetime — latest start. Defaults to 7 days out. |
| limit | integer | – | Max results to return (1-30, default 15). |
| max_price | number | – | Maximum price in GBP. Published prices above this are removed; unpublished-price slots ('Check App', common for padel/tennis) are kept and flagged. |
| sport | string | – | One of Football, Tennis, Squash, Padel, Swimming. |
| time_from | string | – | London-local earliest start time of day, 'HH:MM' (e.g. '18:00'). Samples the soonest upcoming slots; combine with date_from to target a specific day. |
| time_to | string | – | London-local latest start time of day, 'HH:MM'. |
