Legalize — Claude Code MCP server: what it does, how to install
Connects your AI client to a consolidated legal corpus to pull exact statutory wording on any historical date with git commit citations.
claude mcp add --transport http legalize https://legalize.dev/mcpWhat Legalize does
Legalize is a remote Streamable HTTP server hosted at https://legalize.dev/mcp. You do not install local packages. When an agent queries a statute, the server returns complete articles instead of fragmented snippets. Each answer provides the text and the git commit SHA backing the quote.
The underlying legal corpus remains strictly read-only. Calling tools requires signing into Legalize on the first request. You can inspect unified diffs between two historical dates with diff_law or view amending norms via reform_history. Creating alert webhooks or daily email digests requires an active paid account.
What it helps with
- retrieve full statutory text by law title or official number
- look up the exact wording of a law on a historical date
- inspect unified diffs between two versions of legislation
- trace the history of amendments modifying a statute
Example prompts for the agent
- Retrieve the wording of this statute on June 15 2018 with git commit citations.
- Run diff_law to see changes between the 2015 and 2022 versions of this law.
- Show the amendment history for this norm using reform_history.
