find_case
Fast direct lookup: give a citation or a case caption and get THE case (or 'not decisive' with up to 5 candidates) without a full-text search. Use search_cases for topics and words. A citation ("384 U.S. 436", "Miranda v. Arizona, 384…

export_document
Optional. If your client can save files locally and you want a readable copy of a case or statute, this returns the complete document to save; otherwise use get_case / get_statute as before. The document is the syfert.com page as the…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "legal-research": {
      "type": "http",
      "url": "https://mcp.syfert.com/mcp"
    }
  }
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
