      "command": "npx",

This MCP Server provides real-time access to Singapore’s LTA DataMall API, delivering up-to-date bus arrivals, traffic conditions, train service updates, and other transit-related data to your MCP clients. It enables you to build responsive transport-aware applications that react to live mobility information.

How to use

You interact with this MCP Server through your MCP client by specifying the server name as a source. It exposes real-time data endpoints such as bus arrivals, station crowding, train alerts, carpark availability, travel times, traffic incidents, and crowd forecast. Use the client to request information for specific inputs (for example, a bus stop code or train line) and receive structured results suitable for dashboards, alerts, or route planning.

How to install

Prerequisites: you need Node.js and npm installed on your system.

npx -y @smithery/cli install @arjunkmrm/mcp-sg-lta --client claude

Configuration and usage notes

API access requires an LTA DataMall API key. Obtain your key by registering an account, subscribing to the API services, and retrieving the key from your account dashboard. When you configure the client, provide this key as an environment variable to authorize requests to the LTA DataMall.

Add the MCP server configuration to your Claude Desktop setup to enable the server: you will place the configuration in your claude_desktop_config.json under mcpServers. The example below shows how to reference the MCP server using npx with the appropriate arguments and environment variable for the API key.

{
  "mcpServers": {
    "lta": {
        "command": "npx", 
        "args": [
          "-y", 
          "arjunkmrm/mcp-sg-lta"
        ],
        "env": {
          "LTA_API_KEY": "YOUR-API-KEY"
        }
    }
  }
}
