Use this skill whenever a matter needs LIVE legal research — case law, dockets, judges, or law outside the snapshotted corpora — via the bundled free CourtListener and Legal Data Hunter MCP servers, never from memory or generic web search. Triggers include "find case law", "cases on point", "is there precedent for", "what did the court hold in", "look up this opinion", "verify this citation", "is this case real", "cite-check", "is this still good law", "shepardize", "negative treatment…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Case-Law Research (bundled MCP servers) > **NOT LEGAL ADVICE.** This skill retrieves and organizes legal sources as a research and > drafting aid. It does not evaluate whether an authority is good law on the user's facts and > does not create an attorney-client relationship. Verify everything against the primary source > before relying on or filing anything. ## Purpose The marketplace deliberately snapshots **rules** (statutes, regulations, court rules) verbatim in each plugin's references corpus, but **case law is never snapshotted** — it is too large and moves too fast. This skill is the live-lookup layer. This plugin bundles two free remote MCP servers (declared in [`../../.mcp.json`](../../.mcp.json)), and because every state plugin depends on this plugin, they are connected anywhere any claude-legal plugin is installed: | Server | Use it for | |---|---| | **CourtListener** (`https://mcp.courtlistener.com/`, Free Law Project) | U.S. case law (federal + all 50 states), RECAP/PACER federal dockets and filings, judges, oral arguments, citation verification | …

How to install
mdr add codearranger/claude-legal/case-law-research@sha256:02dec44a5384556bThe line at the top of this page pins the label v0.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
