What this server can do
1 function, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
check_contractor(name, offset, license, jurisdiction)- Check a contractor's license against official state and local licensing records covering dozens of US jurisdictions. The covered set grows over time; GET /v1/coverage on this host for the exact current list, and never assume from this description whether a jurisdiction is covered. Provide a license number or a business name, plus the jurisdiction. Returns match (the license record with status and provenance), candidates (disambiguate and call again; page with offset), no_match_in_index (NOT a determination of unlicensure), or jurisdiction_not_covered (with an official pointer URL for that jurisdiction; the response message states exactly what the link is, which for some jurisdictions is a consumer-protection or licensing-board page rather than a license lookup, so relay the message's wording and never present the link as a license lookup unless the message says it is one).

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
