What I built

I created Trello MCP Server, a lightweight backend that lets Claude Desktop interact with Trello boards, lists, and cards via natural language. It supports reading, creating, updating, and deleting Trello elements through a simple Python interface. I chose Trello because it is not only my daily driver for my personal projects, but also my shopping list, guitar learning database etc. 😄

How I built it

Built in Python using the uv package manager (my first time using it), the server connects to Trello’s API and handles user input via Claude. I focused on clean API integration and strong error handling.

Challenges I faced

• Learning to manage Python environments with uv as a Java/TypeScript developer
• Dealing with Trello API permissions, limitations, and inconsistent responses

What I learned

• Efficient Python environment management with uv
• Working with third-party APIs and AI integrations
• Building fault-tolerant middleware

Tips for others

• Use uv for fast and easy Python setup
• Handle API edge cases early
• Design your system to expect unpredictable input from AI agents
