Koskamo

Houki e-Gov MCP

This MCP server retrieves Japanese statutes (Constitution, laws, ordinances, ministerial ordinances, rules) from the e-Gov Law API v2. It returns legal text by article, paragraph, and item, including law numbers and URLs. It supports searching by law name or abbreviation, retrieving revision history, resolving abbreviations, and verifying citations, enabling agents to check primary legal sources for tax, labor, and corporate procedures.
