Connect e-Gov Law Search to Copilot Studio
Query e-Gov Law Search directly from Copilot Studio. Arlet links the two through one MCP connection and takes care of API keys.
This server connects your AI client to the e-Gov Laws API (Version 2), the official database of Japanese legislation operated by the Digital Agency. It covers the Constitution, acts, cabinet orders, imperial orders, ministerial ordinances, and rules.
Key features:
- Find laws by title (partial match) or by law number, optionally filtered by law type.
- Run a full-text keyword search across the body text of all current laws and get matching sentence snippets.
- Fetch the text of a law as readable plain text. Long laws are truncated, so you can point at a specific article (e.g. MainProvision-Article_90) or request the text as it stood on a past date (asof).
- List a law's amendment history: amending laws, promulgation and enforcement dates, and future scheduled amendments.
The e-Gov Laws API is a public API provided free of charge by the Japanese government, so no API key or account is required. Results always reflect the official consolidated text published on e-Gov.
