Legalize MCP server

What it does

Legalize provides access to a read-only corpus of consolidated legislation across multiple countries. It lets you query laws by date, search their history, and retrieve exact text with citations and git commit references. This is for developers building AI applications that need to reference legislation with verifiable sources.

• Retrieve the exact wording of a law as it stood on a specific past date, with the git SHA for verification.
• Search for legislation by title keywords or official number across the supported countries in the corpus.
• Generate a unified diff showing what changed in a law between two dates, and see which other laws amended it.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
