Plugrail provides a suite of Model Context Protocol (MCP) servers that connect Japanese public data sources—such as holiday calendars, corporate registration, nutrition information, and product recall data—to AI agents. By exposing this data via streamable HTTP endpoints, developers can query authoritative information without needing to manage raw datasets. The service offers free anonymous access with rate‑limited usage and paid plans for higher volume, and it includes clear source citations and disclaimer notices. Plugrail aims to simplify integration of public sector data into AI‑driven workflows.
