UBOS Asset Marketplace: JR East Delay Information via MCP Server

In the rapidly evolving landscape of AI-driven applications, contextual awareness is paramount. To ensure that Large Language Models (LLMs) can provide accurate, relevant, and timely information, they must seamlessly integrate with real-world data sources. The UBOS Asset Marketplace offers a powerful solution: the JR East Delay Information MCP (Model Context Protocol) Server. This server acts as a crucial bridge, enabling AI agents to access and utilize real-time delay information from JR East Japan, one of the country’s largest railway operators.

What is MCP and Why Does It Matter?

Before diving into the specifics of the JR East Delay Information MCP Server, it’s essential to understand the fundamental role of MCP in modern AI architecture. MCP is an open protocol that standardizes how applications provide context to LLMs. It addresses a critical challenge: LLMs, while powerful, are inherently limited by the data they were trained on. They lack real-time awareness and the ability to interact with external systems. Without a mechanism to access current information, LLMs risk generating outdated, inaccurate, or irrelevant responses.

MCP solves this problem by providing a standardized interface for LLMs to query external data sources and tools. An MCP server acts as a mediator, translating requests from the LLM into specific actions on the external system and then formatting the response back for the LLM to interpret. This enables AI agents to:

• Access Real-Time Information: Query live data feeds, such as weather updates, stock prices, news articles, and, in this case, railway delay information.
• Interact with External Tools: Trigger actions on other systems, such as sending emails, updating databases, or controlling IoT devices.
• Personalize User Experiences: Tailor responses based on user context, location, and preferences.
• Improve Accuracy and Relevance: Ensure that LLM-generated content is grounded in current and reliable information.

4. Smart City Initiatives: Integrating delay data with city-wide transportation management systems can enable dynamic traffic light adjustments and optimized public transportation schedules.

Technical Details

The MCP Server is built using Node.js and can be easily installed and configured using npm. The provided documentation includes detailed instructions on setting up the server and integrating it with MCP clients.

Setup:

sh npm install

Build:

sh npm run build

Testing:

sh npx vitest run

Server Startup:

sh node build/index.js

Alternatively, using the bin setting in package.json:

sh npx jr-east-delay

MCP Client Configuration Examples

To use this server with clients like Claude Desktop or MCP Inspector, configure your client settings (e.g., claude_desktop_config.json) as follows:

Example 1: When node command is in PATH

“jr-east-delay”: { “command”: “node”, “args”: [“/Users/your-path/mcp-jr-east-delay/build/index.js”] }

Example 2: Specifying the absolute path of node

“jr-east-delay”: { “command”: “/Users/your-username/.nodebrew/current/bin/node”, “args”: [“/Users/your-path/mcp-jr-east-delay/build/index.js”] }

• Replace your-username with your actual username.
• Replace your-path with the correct path to the server.
• If the node command isn’t in your PATH, specify the absolute path.

Development Notes

• Tests are located in src/index.test.ts
• Use MCP Inspector or similar client for MCP protocol communication testing.
