Usage from MCP Clients

You can obtain JR East delay information by calling the getDelays tool from MCP clients such as Claude Desktop or MCP Inspector.

Example of MCP Client Configuration

When using this server with clients like Claude Desktop or MCP Inspector, please configure your settings file (e.g., claude_desktop_config.json) as follows.

Example 1: When the node command is available in the PATH

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

Example 2: Specifying the absolute path to node

json
"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 actual path on your system.
• If the node command is not available in the PATH, specify the absolute path.

Development Notes

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