What the publisher says

From the Trello repository's README, as published. We do not edit it. Read it on GitHub

trellio-mcp — MCP Server for Trello

<!-- mcp-name: io.github.scaratec/trellio-mcp -->

An MCP server that gives Claude Desktop, Claude Code, and Gemini CLI full access to the Trello API. Built on the trellio async client library and the official Python MCP SDK. Developed following the BDD Guidelines v1.8.0.

Features

one composite getboardoverview tool

  • 48 MCP tools — 1:1 mapping to trellio methods, plus

trello://card/{id} for rich context loading

  • 2 resource templates — trello://board/{id} and

daily_standup as workflow shortcuts

  • 3 prompts — summarizeboard, createsprint,

the browser, user clicks "Allow", token stored securely

  • Built-in auth flow — python -m trello_mcp auth opens

translated into clear, actionable MCP error messages

  • Structured error handling — Trello API errors are

network surface

  • stdio transport — runs as a local subprocess, no

Tools

Card tools support pos (top/bottom), idLabels (comma-separated), due (ISO 8601), and dueComplete (true/false) on create and update.

Prerequisites

(add http://localhost:8095 to Allowed Origins)

  • Python 3.10+
  • A Trello API Key

Installation

Using pipx (recommended)

To install globally so the trellio-mcp command is available in your PATH:

pipx install trellio-mcp

Alternatively, you can run it on-the-fly without installing:

pipx run trellio-mcp

(Note: If you use pipx run, your MCP client configuration must also use pipx as the command and run trellio-mcp as arguments.)

Using pip

pip install trellio-mcp

From source

git clone https://github.com/scaratec/trellio-mcp.git
cd trellio-mcp
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"

Authentication

Interactive (recommended)

Run the auth command on each machine to connect your Trello account:

If you installed globally (pipx install or pip install):

TRELLO_API_KEY=your_api_key trellio-mcp auth

If using on-the-fly execution (pipx run):

TRELLO_API_KEY=your_api_key pipx run trellio-mcp auth

This opens a browser where you authorize the app. The token is captured automatically and stored in ~/.config/trellio-mcp/credentials.json (permissions 0600).

After auth, no environment variables are needed — the server reads stored credentials on startup.

Environment Variables (fallback)

Shortened. The full README is on GitHub.
