MCP Server for an EV Charging Platform
Fleet managers at a Swiss EV charging infrastructure provider with 5,000+ chargers logged in to a dashboard every morning just to check whether any charger had gone offline overnight. We built a remote MCP server in TypeScript on AWS ECS that exposes the client's existing REST API to Claude and ChatGPT, authenticated through the client's own AWS Cognito user pool with the OAuth 2.1 flow MCP requires. Ten read-only tools shipped first; write tools followed once usage was proven. Customers now run recurring prompts (daily consumption report, weekly cost summary, alert when a charger goes offline) instead of opening the dashboard, and the client was the first in its competitive set to ship an AI-assistant integration.
