## About

# Trello MCP Server

A [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server that connects [Trello](https://trello.com) to Claude Code. Manage your boards, lists, cards, checklists, and more — all through natural language.

> **73 tools** | **Zero config startup** | **Auto-loads `.env`** | **Docker ready** | **Remote HTTP support**

---

## Prerequisites

- [Node.js 22+](https://nodejs.org/)
- [Claude Code CLI](https://docs.anthropic.com/en/docs/claude-code) installed and authenticated
- A Trello account
- [Docker](https://www.docker.com/) (only needed for remote/Docker mode)

---

## Option A: Local Setup (Stdio Mode)

Best for personal use on your own machine. Claude Code launches the server automatically — no Docker needed.

### Step 1: Clone and install

```bash
git clone https://github.com/GabrielRamirez/trello-mcp.git
cd trello-mcp
npm install
```

### Step 2: Get your Trello credentials

Run the interactive setup wizard:

```bash
npm run setup
```

It will:
1. Ask for your API key — get one at [trello.com/power-ups/admin](https://trello.com/power-ups/admin)
2. Open your browser to authorize the app
3. You click **Allow**, copy the token, and paste it back
4. Save both values to a `.env` file automatically

> The `.env` file is git-ignored. Your credentials stay local.

### Step 3: Register the server with Claude Code

```bash
claude mcp add trello -- npx tsx src/index.ts
```

### Step 4: Verify it works

Open Claude Code and ask:

```
List my Trello boards
```

You should see your boards listed. The 73 Trello tools are now available in every Claude Code conversation.

---

## Option B: Docker Setup (Remote HTTP Mode)

Best for running on a server, sharing with a team, or keeping the server always-on. The server exposes an HTTP endpoint that Claude Code connects to via URL.

### Step 1: Clone the repo

```bash
git clone https://github.com/GabrielRamirez/trello-mcp.git
cd trello-mcp
```

### Step 2: Configure credentials

```bash
cp .env.example .env
```

Open `.env` in your editor and fill in your values:

```env
TRELLO_API_KEY=your-api-key-here
TRELLO_TOKEN=your-token-here
```

Need credentials? Get your API key at [trello.com/power-ups/admin](https://trello.com/power-ups/admin), then click the token link on that page to authorize.

### Step 3: Build and start the server

```bash
docker compose up --build
```

You should see:

```
trello-mcp-1  | Trello MCP server listening on http://0.0.0.0:3333/mcp
```

> The server will refuse to start if credentials are missing, with a clear error telling you what's needed.

### Step 4: Verify the server is running

In a new terminal:

```bash
curl http://localhost:3333/health
```

Expected response:

```json
{"status":"ok"}
```

### Step 5: Connect Claude Code to the server

```bash
claude mcp add --transport http trello http://localhost:3333/mcp
```

If the server is running on a remote machine, replace `localhost` with the server's hostname or IP:

```bash
claude mcp add --transport http trello http://your-server:3333/mcp
```

### Step 6: Verify it works

Open Claude Code and ask:

```
List my Trello boards
```

---

## Option C: Using the Published Docker Image

The image is published on [Docker Hub](https://hub.docker.com/r/gabermz/trello-mcp). No cloning or Node.js required.

### Step 1: Run the container

```bash
docker run -d -p 3333:3333 \
  -e TRELLO_API_KEY=your_key \
  -e TRELLO_TOKEN=your_token \
  --name trello-mcp \
  gabermz/trello-mcp
```

### Step 2: Connect Claude Code

```bash
claude mcp add --transport http trello http://localhost:3333/mcp
```

That's it — no Node.js, no cloning, no `npm install`.

---

## Environment Variables

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `TRELLO_API_KEY` | Yes | — | Your Trello API key ([get one here](https://trello.com/power-ups/admin)) |
| `TRELLO_TOKEN` | Yes | — | Your Trello authorization token |
| `PORT` | No | `3333` | HTTP server port (Docker/remote mode only) |

---

## Sharing with Your Team

### Option 1: Project-scoped config

Register the server for everyone working in a specific project:

```bash
claude mcp add --transport http trello --scope project http://localhost:3333/mcp
```

This saves the config to `.mcp.json` in the project root, which you can commit to git.

### Option 2: Manual `.mcp.json` with environment variable support

Create `.mcp.json` in your project root:

```json
{
  "mcpServers": {
    "trello": {
      "type": "http",
      "url": "${TRELLO_MCP_URL:-http://localhost:3333}/mcp"
    }
  }
}
```

Each teammate can set `TRELLO_MCP_URL` to point to their own server, or omit it to use the default `localhost:3333`.

---

## What Can It Do?

Once connected, just ask Claude in natural language:

| You say | What happens |
|---------|--------------|
| *"List my Trello boards"* | Fetches all your boards |
| *"Show me the cards in my Sprint board"* | Gets all cards on that board |
| *"Create a card called Fix login bug in the To Do list"* | Creates a new card |
| *"Move that card to In Progress"* | Moves a card between lists |
| *"Add a checklist called QA Steps to that card"* | Creates a checklist |
| *"Search for cards about authentication"* | Searches across all boards |

## Troubleshooting

| Problem | Solution |
|---------|----------|
| **"Missing required environment variables"** | Copy `.env.example` to `.env` and fill in your credentials, or pass them via `-e` flags. |
| **"Trello API credentials are not configured"** | Run `npm run setup` to configure credentials interactively. |
| **401 Unauthorized** | Your API key or token is invalid. Run `npm run setup` to generate new ones. |
| **Server starts but no tools appear** | Make sure you used `claude mcp add`, not just `npx tsx src/index.ts` directly. |
| **"Cannot find module" errors** | Run `npm install` to install dependencies. |
| **Docker health check failing** | Ensure port 3333 isn't already in use. Check logs with `docker compose logs`. |
| **Can't connect to remote server** | Check firewall rules allow port 3333. Verify with `curl http://your-server:3333/health`. |
