Loupe: free citation lookup

legal.loupe/citation-lookup

このMCPでできること

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.

Find a case by name
Search the case names in Loupe's index, or look up the case a citation names. Give the parties' names, and the year if known. A case missing from the results may still exist.
