## Quality 87/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: ukcrime_list_reference (destructiveHint); ukcrime_search_crimes (destructiveHint); ukcrime_search_outcomes (destructiveHint); …
- pass `tools.token_cost`: about 4,775 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 6 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 100 (weight 15)

- pass `deps.known_vulns`: no known advisory in 74 resolved packages

- 2026-10-18 `ukcrime_find_neighbourhood` changed (inputSchema, outputSchema)
- 2026-10-18 `ukcrime_search_stops` changed (inputSchema, outputSchema)
- 2026-10-18 `ukcrime_get_crime_outcomes` changed (description, inputSchema, outputSchema)
  - before: Fetch the full police outcome history of up to 25 crimes by persistent_id — the 64-character id on crimes from ukcrime_search_crimes and ukcrime_search_outcomes. Returns each crime with every outcome, oldest first, and lists the ids data.police.uk does not hold. Anti-social behaviour records carry no persistent id.
  - after: Fetch the full police outcome history of up to 25 crimes per call by persistent_id — the 64-character id on crimes from ukcrime_search_crimes and ukcrime_search_outcomes. Accepts up to 1,000 raw elements or nonblank delimited tokens and 128,000 aggregate UTF-16 code units; remaining_ids carries unprocessed unique ids for the next call. Returns each crime with every outcome, oldest first, and lists the ids data.police.uk does not hold. Anti-social behaviour records carry no persistent id.
- 2026-10-18 `ukcrime_search_outcomes` changed (description, inputSchema, outputSchema)
  - before: List the police outcomes recorded in one month inside an area — a point with a 1-mile radius, a polygon, a location_id, or a neighbourhood — for crimes recorded that month or any earlier one. Returns the total, counts by outcome and by the month each crime was recorded, and a page of outcomes, each with its crime and persistent_id. Use it for what police resolved in a month; ukcrime_search_crimes gives the latest outcome of the crimes recorded in a month instead. Court results are not published; the result says when a force publishes no outcomes.
  - after: List the police outcomes recorded in one month inside an area — a point with a 1-mile radius, a polygon, a location_id, or a neighbourhood — for crimes recorded that month or any earlier one. Returns the total, counts by crime category, outcome and the month each crime was recorded, and a page of outcomes, each with its crime and persistent_id. Use it for what police resolved in a month; ukcrime_search_crimes gives the latest outcome of the crimes recorded in a month instead. Court results are not published; the result says when a force publishes no outcomes.

## Tools (6)

- `ukcrime_find_neighbourhood`: Find the police force and neighbourhood policing team for a point, or look one up by force and neighbourhood id. Returns the team's description, contact channels and police stations, its current priorities with the action taken, team members' ranks and names, and upcoming engagement events. include adds the boundary polygon, needed only to split a neighbourhood too large to search into smaller polygons: ukcrime_search_crimes, ukcrime_search_outcomes and ukcrime_search_stops take the neighbourhood directly through area 'neighbourhood'.
- `ukcrime_get_crime_outcomes`: Fetch the full police outcome history of up to 25 crimes per call by persistent_id — the 64-character id on crimes from ukcrime_search_crimes and ukcrime_search_outcomes. Accepts up to 1,000 raw elements or nonblank delimited tokens and 128,000 aggregate UTF-16 code units; remaining_ids carries unprocessed unique ids for the next call. Returns each crime with every outcome, oldest first, and lists the ids data.police.uk does not hold. Anti-social behaviour records carry no persistent id.
- `ukcrime_list_reference`: Decode the vocabulary the other ukcrime tools take: police force ids, crime category slugs, a force's neighbourhood ids, and data availability — the published months, and which forces published stop and search in each. Use it when a force, category, neighbourhood id or month is unknown; name_contains filters forces and neighbourhoods by name. The Metropolitan Police has about 680 neighbourhoods, so filter by name there; to get the force and neighbourhood covering a latitude and longitude, call ukcrime_find_neighbourhood instead.
- `ukcrime_search_crimes`: Search street-level crimes recorded in one month, or with month_from a range of up to 12 months, inside an area — a point with a 1-mile radius, a polygon, a snapped location_id from an earlier result, or a police neighbourhood — or list the crimes a force could not place on the map (area 'force_unplaced'). Returns the total, counts by category and by latest police outcome, the busiest map points, each month's total for a range, and a page of crimes, each with the persistent_id that ukcrime_get_crime_outcomes takes; for what police resolved in a month, whenever the crime was recorded, use ukcrime_search_outcomes. Locations are anonymised map points, not crime sites. data.police.uk can refuse an area holding more than about 10,000 crimes, whatever the category — then search smaller polygons.
- `ukcrime_search_outcomes`: List the police outcomes recorded in one month inside an area — a point with a 1-mile radius, a polygon, a location_id, or a neighbourhood — for crimes recorded that month or any earlier one. Returns the total, counts by crime category, outcome and the month each crime was recorded, and a page of outcomes, each with its crime and persistent_id. Use it for what police resolved in a month; ukcrime_search_crimes gives the latest outcome of the crimes recorded in a month instead. Court results are not published; the result says when a force publishes no outcomes.
- `ukcrime_search_stops`: Search police stop and search records for one month, or with month_from a range of up to 12 months, inside an area — a point with a 1-mile radius, a polygon, a location_id from an earlier result, or a police neighbourhood — or across a whole force with area 'force', which includes stops the force could not place. Returns the total and counts by search type, self-defined and officer-defined ethnicity, outcome, object of search, legislation, age range, gender, whether the outcome was linked to the object of search, and whether more than outer clothing was removed, each month's total for a range, and a page of stops. filters narrow the counts and the page together, so filtering one field and reading another's breakdown gives a cross-tab. Forces skip months and some publish none; the result names each force it finds for the area that did not publish, with the months it skipped.
