MCP Trello

A Model Context Protocol (MCP) server that provides tools for interacting with Trello boards. This server enables seamless integration with Trello’s API while handling rate limiting, type safety, and error handling automatically.

Features

• Full Trello Board Integration: Interact with cards, lists, and board activities
• Built-in Rate Limiting: Respects Trello’s API limits (300 requests/10s per API key, 100 requests/10s per token)
• Type-Safe Implementation: Written in TypeScript with comprehensive type definitions
• Input Validation: Robust validation for all API inputs using Zod schemas
• Error Handling: Graceful error handling with informative messages

Core Components

• MCP Servers: These servers act as bridges, exposing APIs, databases, and code libraries to external AI hosts. By implementing an MCP server in TypeScript, developers can share data sources or computational logic in a standardized way using JSON-RPC 2.0.
• MCP Clients: These are the consumer-facing side of MCP, communicating with servers to query data or perform actions. MCP clients use TypeScript SDKs, ensuring type-safe interactions and uniform approach to tool usage.
• MCP Hosts: Systems such as Claude, Cursor, Windsurf, Cline, and other TypeScript-based platforms coordinate requests between servers and clients, ensuring seamless data flow. A single MCP server can thus be accessed by multiple AI hosts without custom integrations.

Available Tools

MCP Trello provides the following tools for interacting with Trello:

Board Management

• getMyBoards: Retrieve all boards for the authenticated user (useful for finding board IDs)

Card Management

• getCardsByList: Fetch all cards from a specific list
• getMyCards: Fetch all cards assigned to the current user (works without board ID)
• addCard: Add a new card to a specified list
• updateCard: Update an existing card’s details (name, description, due dates, labels, position)
• moveCard: Move a card to a different list or board
• archiveCard: Send a card to the archive
• changeCardMembers: Add or remove members from a card

List Management

• getLists: Retrieve all lists from the configured board (requires board ID)
• addList: Add a new list to the board (requires board ID)
• archiveList: Send a list to the archive

Board Information

• getRecentActivity: Fetch recent activity on the board (requires board ID)
