Safety notes

Trello MCP Server can create, read, update, move, archive, and delete board data depending on token permissions and requested tools.
Card, checklist, label, due-date, start-date, comment, attachment, board, list, workspace, and active-board changes can affect real team workflows.
File attachments are added from URLs; review source URLs and destination cards before allowing an agent to attach files.
Use `TRELLO_ALLOWED_WORKSPACES` to limit workspace access, especially when a token can see personal, client, or production boards.
Require confirmation before creating boards, adding attachments, deleting or archiving cards, changing due dates, moving cards between lists, or posting comments on behalf of a user.

Privacy notes

Trello API keys, tokens, board IDs, workspace IDs, card IDs, member names, labels, comments, checklists, attachments, due dates, and activity logs can be exposed to the MCP client.
Active board and workspace selections may persist locally in Trello MCP configuration.
Card descriptions, comments, attachments, and activity histories can contain private customer, roadmap, incident, or operational data.
Proxy settings, Trello credentials, and workspace allowlists should be kept out of shared MCP configs, logs, screenshots, and transcripts.
Response previews reduce some large card-description exposure, but full-card and activity tools can still return sensitive Trello content.

Prerequisites

Trello API key and token with access to the boards and workspaces Claude may use.
Bun-compatible published package runtime or an MCP client that can launch the packaged stdio server through npx.
Optional `TRELLO_BOARD_ID` or `TRELLO_WORKSPACE_ID` when a default board or workspace should be selected at startup.
Optional `TRELLO_ALLOWED_WORKSPACES` to constrain the token to specific approved Trello workspaces.
Review of which boards, lists, cards, labels, comments, checklists, attachments, members, and workspace actions the token can read or change.

About this resource

Content

Trello MCP Server connects Claude and other MCP clients to Trello boards through the Trello API. It provides tools for cards, lists, board activity, comments, checklists, attachments, labels, workspace selection, board selection, and health checks while respecting Trello API rate limits.

Use it when Claude needs supervised access to Trello planning, triage, operations, product, support, or kanban workflows.

Source Review

These sources were reviewed on 2026-06-06. Prefer the live repository, README, npm metadata, license, package metadata, server entrypoint, Trello API client, health endpoints, skill instructions, and setup reference for current setup and behavior details.

Features

List boards, workspaces, lists, cards, comments, checklists, labels, and board activity.
Create cards, update card details, move cards, manage due dates and start dates, and work with labels.
Add, update, delete, and retrieve comments on Trello cards.
Fetch complete card data including checklists, attachments, labels, members, comments, and markdown-formatted output.
Add file attachments from URLs.
Switch active boards and workspaces without restarting the MCP server.
Restrict accessible workspaces with TRELLO_ALLOWED_WORKSPACES.
Use built-in Trello API rate-limit handling and health endpoints.

Installation

Create a Trello API key and token, then configure the MCP server with the credentials and any desired workspace restrictions:

{
  "mcpServers": {
    "trello": {
      "command": "npx",
      "args": ["@delorenj/mcp-server-trello"],
      "env": {
        "TRELLO_API_KEY": "your-api-key",
        "TRELLO_TOKEN": "your-token",
        "TRELLO_ALLOWED_WORKSPACES": "workspace-id-1,workspace-id-2"
      }
    }
  }
}

Set a default board or workspace only when you want the server to start scoped to that location:

TRELLO_BOARD_ID=your-board-id
TRELLO_WORKSPACE_ID=your-workspace-id

Use Cases

Summarize recent activity across a project board.
Create cards from meeting notes or support follow-ups.
Update due dates, labels, comments, and checklist items after review.
Find cards by list, label, name, due date, or board context.
Export card data as markdown for reports or handoffs.
Limit an assistant to specific Trello workspaces for safer operational use.

Safety and Privacy

Trello MCP Server acts through a real Trello API token. Scope the token and workspace allowlist tightly, keep destructive operations behind confirmation, and test workflows on non-production boards before using Claude on shared team boards.

Treat Trello board names, card descriptions, comments, attachments, labels, checklists, members, due dates, activity logs, API keys, tokens, board IDs, and workspace IDs as sensitive operational data. Avoid placing credentials or private card content in shared prompts, logs, screenshots, or public examples.
