Qué hace este MCP

Checks US legal citations and searches an indexed collection of cases by party names or citation.

check_citation
Check a citation
Check one US legal citation, or a sentence holding a few: whether it exists in the sources Loupe checks, which case it is, and whether a pin cite falls inside the opinion. Give it exactly as written, with the case name and year if the document has them, because the commonest error is a real citation attached to the wrong case.
