Product overview
What is America's Law Graph?
America's Law Graph is an MCP server that gives Claude, Cursor, and other MCP-compatible AI agents access to U.S. statutory law. Its published dataset contains 529,386 sections across 5,164 statutes, codes, and regulations, covering all 50 states, the District of Columbia, the United States Code, and the Code of Federal Regulations.
The server supports keyword and fuzzy search, semantic retrieval, citation-graph traversal, statute structure, recent changes, jurisdiction comparison, regulatory risk analysis, and doctrinal lineage. It is useful for research and discovery, but the repository identifies the service as proprietary rather than open source.
