To-Do MCP Server with TypeScript

Overview

• Authentication with Kinde
• Data persistence with Neon Postgres
• Billing enforcement with a free tier and upgrade path
• MCP tool exposure so all of this works seamlessly

Dependencies

• @modelcontextprotocol/sdk package gives us everything we need to build and expose MCP servers and tools.
• @neondatabase/serverless to connect to a Neon Postgres database
• @kinde-oss/kinde-typescript-sdk handles authentication and billing through Kinde.
• express to define routes and handle middleware
• jsonwebtoken + jwks-client to verify tokens with Kinde
• express-session will take care of managing session state so users can stay logged in across requests.
