Topos Tech LLC has expanded its city information service, ‘Topo,’ by integrating mobile applications, web platforms, and ChatGPT. The update includes the release of Topo v1.2 for iPhone and a dedicated ChatGPT plugin.

The service utilizes a proprietary ‘Context Gateway’ system and the Model Context Protocol (MCP) to enable AI agents to report on local events, shop information, and disaster updates. In Japan, the service will focus on eight cities, including Shibuya, Kyoto, Osaka, and Sapporo. The development of this automated observation system was motivated by the necessity of distributing rapid disaster information following recent heavy rain events in Kumamoto, Chiba, and Fukui.
