What it does

This MCP App embeds an interactive map UI directly into the chat, allowing users to browse GSI tiles, search for Japanese addresses, and retrieve specific tile information via a sandboxed iframe.

Key features

Interactive Map View: Zoom, pan, and switch between different GSI layers (Standard, Pale, Seamless Photo, Optimized Vector).
Address Search: Integrated GSI address search API to locate specific places in Japan.
Tile Information: Ability to retrieve Z/X/Y coordinates and layer URLs for any given latitude and longitude.
Bidirectional Communication: Syncs current map view coordinates back to the LLM for context.
