LexAtlas — Claude Code MCP server: legal search and setup
LexAtlas searches legal provisions and checks citations in drafts. Connect it when an agent needs to verify a statute, its status, or its amendment history.
claude mcp add --transport http lexatlas-mcp https://api.lexatlas.creatora.app/mcpWhat LexAtlas does
Search provisions by wording or by describing a situation, then retrieve an article’s text and check whether it is in force. LexAtlas can also return a version from a chosen date, trace amendments, and show links between provisions. Other tools review legal references in a draft and check names against official sanctions lists.
LexAtlas runs as a remote MCP server. In Claude Code, add it with a command and sign in from the /mcp menu; OAuth is supported. Clients without OAuth can send an API key with each request. Tool calls use the monthly free allowance first, then draw on your balance.

- find a legal provision from a description of a situation
- check whether an article is in force
