Metro MCP
AI chatbot interface for Washington Metro transit APIs
Overview
Metro MCP connects AI chatbots to the Washington Metro system. Instead of tapping through apps, you can ask questions in plain English like "When's the next Red Line train at Dupont Circle?" and get instant answers.
Challenge & Approach
Getting Metro information means opening an app and clicking through multiple screens. There's no way to just ask a question and get an answer.
Built a bridge between AI chatbots and Metro's data. Now you can ask questions in plain English and get real-time answers about trains, delays, and routes.
Key Features & Implementation
Built server that lets AI chatbots understand and answer Metro questions
Deployed on Cloudflare Workers so responses are instant, no matter the load
Added retry logic so it works reliably even when Metro's APIs have issues
Created login system that's secure but easy for developers to use
Tuned the AI to understand transit questions and return accurate answers
