Fbi Crime MCP Server missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

fbi
fbi_get_arrests
Arrest counts reported to FBI CDE for the nation, a state, or an agency, summed over a month window from January 1985 through the current year. Returns arrests by offense name, offense category, and detailed offense breakdown, by arrestee sex and race, and by age group for male and female arrestees, with every category CDE reports, zeros included. Each grouping is tallied separately and their sums can differ (arrestee sex and race often total less than the offense groupings), so no grouping stands in for another's total. Narrow to one offense with offense. National scope omits identifiers; state requires only state_abbr; agency requires only ori (look it up with fbi_search_agencies). CDE returns zeros both when nothing was reported and when it does not recognize a state or ORI.
fbi_get_crime_estimates
Monthly offense rates (per 100,000 participating population), raw counts, population denominators and provider reporting coverage from FBI CDE, January 1985 through the current year; current-year months past the latest data return null values. National scope omits identifiers; state requires only state_abbr; agency requires only ori. Identifiers are case-insensitive; start must be no later than end. Set include_comparisons on state or agency scope to also get the comparison rates CDE sends for the same months (an agency's state and the United States, or a state's United States). Results use the largest chronological prefix within 24,000 UTF-8 bytes of serialized {content, structuredContent}, excluding SDK protocol metadata and transport framing; next_from supplies the next start with the same scope, identifiers, offense, comparison flag and original end date. An indivisible oversize month and its metadata are returned intact with oversize_notice. Missing coverage stays null and participation may be incomplete. Offenses: violent-crime, property-crime, robbery, burglary, larceny, motor-vehicle-theft, arson, aggravated-assault, rape, homicide.
fbi_get_hate_crimes
Hate crime counts reported to FBI CDE for the nation, a state, or an agency, summed over a month window from January 1991 through the current year. Returns incidents by bias motivation and bias category, plus counts by offense type, location type, offender race, offender ethnicity, and federal judicial district, with every category CDE reports, zeros included. Narrow to one bias motivation with bias. National scope omits identifiers; state requires only state_abbr; agency requires only ori (look it up with fbi_search_agencies). CDE returns zeros both when nothing was reported and when it does not recognize a state or ORI.
fbi_get_leoka
LEOKA officer fatality trends, weapons, activity, circumstances, demographics, geographic regions, and time-of-day/month breakdowns, 2020 through the current year. Period "ytd" requests a year; "monthly" requires month and includes the same month of the comparison year. Both periods return the CDE YTD totals block, separately from month-specific breakdowns. Raw dod/doi totals have unspecified interpretation; classified deaths remain in the trend and region series.
fbi_get_nibrs_breakdown
NIBRS incident breakdowns reported to FBI CDE for one offense, for the nation, a state, or an agency, summed over a month window from January 1991 through the current year. Returns victim counts by age, sex, race, location, ethnicity, and relationship to the offender; offender counts by age, sex, race, and ethnicity; and offense counts by weapon and related offense, with every category CDE reports, zeros included. Each dimension is tallied separately and their sums can differ, so no dimension stands in for another's total. offense is required (codes are listed on the field). National scope omits identifiers; state requires only state_abbr; agency requires only ori (look it up with fbi_search_agencies). When CDE has no value for any category, as for an unrecognized state or ORI, a window with no NIBRS data, or an offense with no reported incidents in the window, the call fails with no_data.
fbi_search_agencies
Find law enforcement agencies in one state and their nine-character ORI codes, the identifier agency scope needs in fbi_get_crime_estimates, fbi_get_hate_crimes, fbi_get_arrests, and fbi_get_nibrs_breakdown. Fetches the state's full FBI CDE agency directory, filters it by words in the agency name, county, and agency type, sorts by agency name then ORI, and returns one page with the total match count and next_offset for the following page. Each agency carries its type, counties, and NIBRS reporting status. A code CDE has no directory for (AS, MP, or an unrecognized code) returns zero agencies with a notice.

Fbi Crime MCP Server — questions

Answers built from our own checks of this server.

What can Fbi Crime MCP Server do?
It exposes 6 tools, read directly from the server on our last check. Among them: fbi_get_arrests, fbi_get_crime_estimates, fbi_get_hate_crimes, fbi_get_leoka, fbi_get_nibrs_breakdown, fbi_search_agencies. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Fbi Crime MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 541 ms. The bar chart above shows every period we have measured.
How do I connect Fbi Crime MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Fbi Crime MCP Server need an API key?
No. Fbi Crime MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Fbi Crime MCP Server?
It answers our handshake in 541 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Fbi Crime MCP Server?
The npm package @cyanheads/fbi-crime-mcp-server was installed 420 times in the last week. Week over week that is +352%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Fbi Crime MCP Server open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at fbi-crime.caseyjhand.com, which runs on its operator's own terms.
