Who it is for
Attorneys, legal researchers, journalists and self-represented litigants working with primary sources.
CourtListener
U.S. case law, PACER dockets and citation data from CourtListener
Overview
What CourtListener does
CourtListener is the legal research platform run by Free Law Project, a nonprofit that publishes primary law rather than selling access to a proprietary corpus. The connector reaches judicial opinions from federal and state courts, PACER docket records, judge profiles, oral argument recordings and citation data. Described operations include searching case law, retrieving case metadata, extracting citations from text and checking them against the database, and setting alerts that fire on new opinions or docket activity.
Fourteen tools are claimed and the connector carries partner tier. Credentials are needed before anything is reachable.
Tool surface
Fourteen tools are claimed against a corpus spanning opinions, dockets and citations; the endpoint asks for credentials first, so how that surface divides is not observable here.
Availability
Where CourtListener is listed
CourtListener is listed in the Claude connectors directory only. Free Law Project has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
CourtListener publishes 14 tools to Claude. That is a mid-sized surface: 56.6% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 2 tools above its bucket's median and ranks 206th of 462 by tool count.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
CourtListener publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

CourtListener carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
