feat(category): accept space and underscore variants of category slugs

Use case

ukcrime_search_crimes and ukcrime_search_outcomes match category only against the exact slug or the exact lower-cased display name, so variants that map one-to-one onto a single category fail with unknown_category. force already folds runs of spaces and underscores to -; category does not.

bug(ukcrime_search_outcomes): a cold outcomes month times out at 30 s and fails the call

Server version

0.1.1

mcp-ts-core version

0.13.10

Runtime

Bun

Runtime version

1.4.2

Transport

HTTP (Streamable HTTP)

Description

data.police.uk can take longer than the 30 s attempt timeout to answer an uncached outcomes month at a busy point. The server aborts the attempt, resends it, and fails the call at the 45 s deadline with no hint, though the same call moments later answers in under a second. The 30 s timeout was sized on crime routes; cold…

bug(police-api): failures that outlast the retries carry no reason, retry flag or hint

Runtime

Bun

Runtime version

1.4.2

Transport

HTTP (Streamable HTTP)

Description

When data.police.uk keeps failing past the retry loop, the caller gets an error with no reason, no retryable and no recovery hint, so a content[]-only client can't tell a passing outage from a bad request. upstream_unavailable (declared retryable: true) is raised only by the area-route 503 probe, and only the three search…

bug(search): zero-hit notice suggests retries in a force that publishes nothing

Server version

0.13.10

Runtime

Bun

Runtime version

1.4.2

Transport

HTTP (Streamable HTTP)

Description

A zero-result search in a force that publishes nothing for that dataset carries the force's coverage note and then the generic zero-hit line, which recommends retries that cannot help. The force_unplaced arm of ukcrime_search_crimes already drops the generic line for such a force; the point and neighbourhood arms of…

feat(search): month range with per-month totals on crimes and stop and search

Use case

The most common question people bring to street-level crime data is a trend: is burglary up in this neighbourhood over the last year, and did stop and search rise after an operation? Every search takes one month, so a 12-month trend takes 12 calls (2–3.4 KB each per surface even at limit: 1, at a Carlisle point), and the caller has to stitch the totals together with no single view of the months a force skipped stop and search.

feat(force): accept a force's display name as well as its id

Use case

Every force input takes only the id (leicestershire), but people and models name forces the way /forces prints them. Leicestershire Police, Metropolitan Police and Police Service of Northern Ireland fail as unknown_force and cost a round trip to ukcrime_list_reference; Devon & Cornwall Police, the upstream's own spelling, fails the schema pattern. That advertised pattern, ^[a-z]+(-[a-z]+)*$, also rejects the capitals and spaces the field's description says are…

feat(ukcrime_search_stops): filter and break down by the find and strip-search flags

Use case

Stop and search research turns on two measures ukcrime_search_stops returns per row but can't count or filter: the find rate (outcome_linked_to_object_of_search) and searches that removed more than outer clothing (removal_of_more_than_outer_clothing). The only way to get either today is to page every stop and count by hand. That takes three 200-row pages of about 110–120 KB each for Cumbria's 537 stops in 2026-08, and a cross-tab like find rate by officer-defined ethnicity…

bug(ukcrime_find_neighbourhood): events capped at 10 with no way to reach the rest

Runtime

Bun

Runtime version

Transport

HTTP (Streamable HTTP)

Description

events is cut to the 10 soonest and events_total reports the full count, but no input reaches the others. Leicester City Centre (leicestershire / NC04) published 26 upcoming events running to 2026-12-22 (checked 2026-10-01), and the result stops at the 10th, on 2026-10-24. That rules out a question like "is there a police…

bug(police-api): rate-limit failures carry no reason, retry flag or wait time

1.4.2

Transport

HTTP (Streamable HTTP)

Description

A data.police.uk 429 reaches the caller as a bare RateLimited error, with no reason, retryable or recovery hint and retryAfter only in structuredContent.error.data, so a content[]-only client sees neither cause nor wait. A Retry-After over the retry loop's 10 s maxDelayMs fails at once, though the call has time left. A…

bug(search): polygon and location searches carry no coverage-gap notice, so no-data forces read as near-zero crime

Server version

mcp-ts-core version

0.13.10

Runtime

Bun

Runtime version

1.4.2

Transport

HTTP (Streamable HTTP)

Description

Coverage notes and force_published appear only when a search knows its force: a named force (neighbourhood, force, force_unplaced) or a located point. polygon and location searches never resolve one, so a polygon over a force that publishes nothing returns a plausible small count with no notice. The same holds for…
