🚀 Trello MCP Server: AI-Powered Project Management

Transform your Trello boards into a living workspace for AI agents. This Model Context Protocol (MCP) server allows LLMs (like Gemini, Claude, and GPT-4) to see, organize, and manage your projects with natural language.

🔍 Overview

This project bridges the gap between AI and your Trello workflow. Instead of manually moving cards, you can tell your AI: "Move all 'To Do' cards with the 'Urgent' label to 'In Progress' and assign them to me."

Global Usage: You can save this project anywhere on your computer. Once registered, your AI will be able to start the server automatically whenever needed—no manual terminal execution required.

📋 Prerequisites

[!TIP] Reordering (the pos parameter):
Use 'top', 'bottom', or a positive number (e.g., 1) to precisely reorder cards, lists, checklists, and items.

🛠️ Troubleshooting

[!WARNING] Server shows as "Disconnected"?

1. Empty Command: If /mcp list shows a red dot, ensure your settings.json (at C:\Users\YourUser\.gemini\settings.json) has "command": "node" correctly set.
2. Environment Variables: Run node dist/index.js manually. If it fails, your .env is likely missing from the root folder.
3. SDK Compatibility: This project uses @modelcontextprotocol/sdk v1.29.0. If you experience protocol errors, run npm install to ensure you have the latest version.

🐳 Docker Support

[!TIP] Docker is perfect for keeping your local environment clean.

# Build
docker build -t trello-mcp-server .

# Run
docker run --rm -i --env-file .env trello-mcp-server
