Cufftracker docs

Cufftracker maps public crime incident records for Chicago, Milwaukee, New York, Minneapolis, and Denver. The map is at cufftracker.com/map. Record counts are at /coverage.

Connect the MCP server

Server URL: https://www.cufftracker.com/mcp
Transport: Streamable HTTP
Sign-in: none

The www host is the server. The bare domain redirects, and some clients stop at the redirect. In Claude, open Settings, then Connectors, add a custom connector, and paste the server URL.

Tools

Every tool is read-only. Results are text plus a JSON block with the same data.

`get_area_trends`

Summarizes incidents inside a neighborhood or rough area: counts by crime type compared with the city, counts by month, the noon-to-midnight share, top streets, and a few notable incidents. Parameters: city (required), place, or all four box edges lat_min, lat_max, lon_min, lon_max, and days (7 to 450, default 90).

`resolve_place`

Returns the lat/lon box for a neighborhood, street, or rough area such as downtown, with suggested get_city_crimes arguments. Parameters: city and place (required), primary_types, days (1 to 90).

`get_city_crimes`

Returns one page of individual incidents. Filters: primary_types, location_descriptions, start_date and end_date (YYYY-MM-DD, default the newest 30 days), search_text, place (address text), and the four box edges. A window longer than 45 days needs a box, a place, or location_descriptions.

`get_crime_stats`

Citywide counts, the date range, top crime types, and top location types. Parameters: city (one city or all, default all) and top_n (1 to 50, default 10).

`search_crimes`

Searches crime types and descriptions. Parameters: query (required), city (default all), limit (1 to 100, default 25, applied per city).

Pagination

get_city_crimes takes limit (1 to 100, default 25) and offset (default 0). The JSON result includes pagination.next_offset, which is the offset of the next page, or null on the last page. Area summaries come from get_area_trends in one call, with no paging.

Data coverage

Chicago's portal withholds about the last seven days.
Milwaukee incidents are live calls for service.
New York publishes complaints after a quarter closes.
Minneapolis addresses are anonymized to the block.
Denver leaves out traffic stops.

A daily job refreshes the data from each city's open-data portal. These are public incident records, not a determination that someone committed a crime.

Examples

How has crime in Harbor View, Milwaukee changed over the last year?
What thefts were reported in Logan Square in the last month?
How do assault counts in Milwaukee compare with Chicago?

Troubleshooting

The connector cannot reach the server: the URL needs the www host.
A neighborhood returns no match: a nearby street, a larger neighborhood, or a rough area such as north side usually resolves.
A long get_city_crimes window is refused: it needs a box, a place, or location_descriptions. get_area_trends covers up to 450 days.
Recent Chicago or New York incidents are missing: those cities publish with a delay.
