How to Set Up and Use Trello
MCP Server Trello connects AI assistants to your Trello boards via the official Trello API, enabling natural language management of boards, lists, cards, checklists, comments, attachments, and custom fields. It includes automatic rate limiting (300 requests per 10 seconds), input validation, and type safety so AI agents can interact with Trello reliably without hitting API limits. Product managers, developers, and teams use it to create and move cards, query task status, update acceptance criteria, and automate project workflows through conversation.
Prerequisites
- A Trello account with at least one workspace and board
- A Trello API key obtained from trello.com/app-key
- A Trello API token generated using your API key (follow the token link on the app-key page)
- Node.js 18+ or Bun installed for running the server
- An MCP-compatible client such as Claude Desktop, Cursor, or Claude Code
Get your Trello API key and token
Go to trello.com/app-key while logged into Trello to get your API key. On the same page, click the Token link to generate a personal access token. Copy both values — you will need them in the MCP config.
# Trello API key page:
# https://trello.com/app-key
# Click 'Token' link on that page to generate TRELLO_TOKENConfigure your MCP client with Trello credentials
Add the Trello MCP server to your MCP client configuration. Use TRELLO_API_KEY and TRELLO_TOKEN from the previous step. Optionally set TRELLO_BOARD_ID to a default board ID to avoid specifying it on every request.

"mcpServers": {
"trello": {
"command": "npx",
"args": ["-y", "@delorenj/mcp-server-trello"],
"env": {
"TRELLO_API_KEY": "your-trello-api-key",
"TRELLO_TOKEN": "your-trello-token"
}
}
}
}Restart your MCP client
Save the configuration file and restart Claude Desktop or your other MCP client. The Trello server will start automatically when the client connects.
List your boards to verify connection
Ask your AI assistant to list your Trello boards. A successful response confirms the API credentials are working and the MCP server can reach the Trello API.
Set an active board for your session
Once boards are listed, ask the AI to set a specific board as active for the current session. This avoids needing to specify the board ID in every subsequent command.

Example natural language Trello management tasks for your AI assistant.
- "List all my Trello boards and show which workspace each belongs to"
- "Show me all cards in the 'In Progress' list on my Dev board"
- "Create a new card called 'Fix login bug' in the To Do list with high priority"
- "Move the 'Update API docs' card to the Done list and add a comment saying it was completed today"
- "Show me all cards assigned to me across all lists on the Sprint board"
- "Add a checklist item 'Write unit tests' to the checkout feature card"Troubleshooting Trello
401 Unauthorized errors when listing boards or cards
Verify that TRELLO_API_KEY matches the key on trello.com/app-key and that TRELLO_TOKEN is a valid token generated for that specific API key. Tokens expire or can be revoked — regenerate the token on trello.com/app-key if needed. Ensure there are no extra spaces or newlines in the env values.
Rate limit errors (429) when running many operations
The server enforces 300 requests per 10 seconds per API key automatically, but burst operations from multiple simultaneous tool calls can still hit limits. Space out bulk operations or break large tasks into smaller sequential steps. The server will retry automatically in most cases.
Cards or lists not found when using board ID
Board IDs in Trello are alphanumeric strings found in the board URL (e.g. trello.com/b/BOARDID/board-name). Use list_boards first to get the correct IDs rather than guessing. If TRELLO_BOARD_ID is set in env but points to a board you no longer have access to, remove it and specify boards per-call instead.
