Legal MCP Server for Claude AI

A developer has built an MCP (Model Context Protocol) server that provides Claude AI with access to over 4 million real US court opinions, eliminating citation hallucinations in legal queries. The tool is free, open-source under MIT license, and has no paid tiers.

Key Features and Tools

The server includes 18 tools covering:

  • Case law search
  • Citation tracing
  • Bluebook citation parsing
  • Clio practice management integration
  • PACER federal filings access

Users can ask Claude questions like:

  • "Find Supreme Court cases about qualified immunity after 2020"
  • "Parse this citation: 347 U.S. 483 (1954)"
  • "Who cited Carpenter v. United States?"

The server returns real cases with accurate citations and links.
