Overview

Nagoya Bus MCP is a Model Context Protocol (MCP) server that lets LLMs query Nagoya City bus information. Built with FastMCP, it exposes tools and prompts for looking up bus stops, reading timetables, and checking real-time bus approach and position information. Data is sourced from the public Nagoya City bus website.

Once connected to an MCP client such as Claude Desktop, you can ask questions like "When is the next bus from Nagoya Station?" in natural language and get answers backed by live data.

Features

The server exposes the following tools:

• get_station_number — find a bus stop number from a stop name (with fuzzy matching).
• get_timetable — departure timetables for every route at a bus stop, organized by day of week.
• get_approach_for_route — real-time bus positions and latest passage times along a route.
• get_approach_for_station — real-time approaching buses for all routes at a bus stop.

It also provides prompt templates ask_timetable and ask_bus_approach for common questions.

Example queries

Bus data is in Japanese, so queries work best in Japanese:

• 「名古屋駅のバスの時刻表を教えて」 (What's the bus timetable at Nagoya Station?)
• 「栄のバスの接近情報を教えて」 (Show real-time bus approach info at Sakae.)
• 「新栄町のバス停番号を教えて」 (What's the bus stop number for Shin-sakaemachi?)
