📋 System Requirements

• Python: 3.12 or higher

• Redmine: Version with REST API support (recommended 4.0+)

• Package Manager: uv or pip

🔧 Installation & Setup

1. Clone the Project

git clone https://github.com/snowild/redmine-mcp.git
cd redmine-mcp

2. Install Dependencies

Using uv (recommended):

uv sync

Or using pip:

pip install -e .

3. Environment Configuration

Create a .env file:

cp .env.example .env

Edit the .env file and set the following environment variables:

REDMINE_DOMAIN=https://your-redmine-domain.com
REDMINE_API_KEY=your_api_key_here

# Project-specific variables (avoid conflicts with other projects)
REDMINE_MCP_LOG_LEVEL=INFO
REDMINE_MCP_TIMEOUT=30

# Backward compatibility variables (fallback)
REDMINE_TIMEOUT=30
LOG_LEVEL=info

Environment Variables Reference

Log Level Priority:

1. REDMINE_MCP_LOG_LEVEL (highest priority - project-specific)

2. LOG_LEVEL (backward compatibility)

3. INFO (default if neither is set)

Note: The system automatically handles case conversion and ensures FastMCP compatibility.

4. Redmine API Setup

4.1 Enable REST API

1. Log in to Redmine as administrator

2. Go to Administration → Settings → API

3. Check "Enable REST web service"

4. Click Save

4.2 Configure Redmine Basic Data (Administrator)

Before using MCP tools, you need to configure Redmine's basic data:

Configure Roles and Permissions

1. Go to Administration → Roles and permissions

2. Create or edit roles (e.g.: Developer, Tester, Project Manager)

3. Assign appropriate permissions to roles (recommend at least: View issues, Add issues, Edit issues)

Configure Trackers

1. Go to Administration → Trackers

2. Create tracker types (e.g.: Bug, Feature, Support)

3. Set default status and workflow for each tracker

Configure Issue Statuses

1. Go to Administration → Issue statuses

2. Create statuses (e.g.: New, In Progress, Resolved, Closed, Rejected)

3. Set status attributes (whether it's a closed status, etc.)

Configure Workflow

1. Go to Administration → Workflow

2. Set allowed status transitions for each role and tracker combination

3. Ensure basic status transition paths (New → In Progress → Resolved → Closed)

Create Projects

1. Go to Projects → New project

2. Set project name, identifier, description

3. Select enabled modules (at least enable "Issue tracking")

4. Assign members and set roles

4.3 Get API Key

1. Log in to your Redmine system (can be administrator or regular user)

2. Go to My account → API access key

3. Click Show or Reset to get the API key

4. Copy the key to REDMINE_API_KEY in the .env file

⚠️ Important Notes:

• If you can't find the API key option, please ensure step 4.1 (Enable REST API) is completed

• Complete basic setup before you can properly create and manage issues

🔗 Claude Code Integration

Install to Claude Code

# Install from local
uv tool install .

# Or using pip
pip install .

# Add to Claude Code MCP configuration
claude mcp add redmine "redmine-mcp" \
  -e REDMINE_DOMAIN="https://your-redmine-domain.com" \
  -e REDMINE_API_KEY="your_api_key_here"

Verify Installation

# Test MCP server
uv run python -m redmine_mcp.server

# Test Claude Code integration
uv run python tests/scripts/claude_integration.py

🌐 SSE Mode & Docker Deployment

Transport Modes

Redmine MCP supports two transport modes:

Running in SSE Mode

Quick Start (Development)

# Navigate to project directory (where .env file is located)
cd /path/to/redmine-mcp

# Run with uv (reads .env automatically)
uv run redmine-mcp --transport sse

# Custom host and port
uv run redmine-mcp --transport sse --host 127.0.0.1 --port 3000

Global Installation

# Install globally
uv tool install . --force --reinstall

# Set environment variables
export REDMINE_DOMAIN=https://your-redmine.com
export REDMINE_API_KEY=your_api_key_here

# Run from anywhere
redmine-mcp --transport sse

Using .env File

Create a .env file in your working directory:

REDMINE_DOMAIN=https://your-redmine.com
REDMINE_API_KEY=your_api_key_here
REDMINE_MCP_TRANSPORT=sse
REDMINE_MCP_PORT=8000

Note: uv run automatically loads .env from the project directory. Global installation requires explicit environment variables or running from the directory containing .env.

Docker Deployment

Quick Start with Docker

# Build the image
docker build -t redmine-mcp .

# Run with environment variables
docker run -d \
  -e REDMINE_DOMAIN=https://your-redmine.com \
  -e REDMINE_API_KEY=your_api_key \
  -p 8000:8000 \
  --name redmine-mcp \
  redmine-mcp

Using Docker Compose

# Edit docker-compose.yml with your Redmine settings
# Then start the service
docker compose up -d

# View logs
docker compose logs -f

# Stop the service
docker compose down

Docker Compose with .env file (Recommended)

1. Create .env file:

REDMINE_DOMAIN=https://your-redmine.com
REDMINE_API_KEY=your_api_key_here

2. Update docker-compose.yml to use environment variables:

environment:
  - REDMINE_DOMAIN=${REDMINE_DOMAIN}
  - REDMINE_API_KEY=${REDMINE_API_KEY}

3. Start the service:

docker compose up -d

Connecting Claude Code to SSE Server

Once the SSE server is running, configure Claude Code to connect:

# Add MCP with SSE transport
claude mcp add --transport sse redmine http://localhost:8000/sse

Or manually edit ~/.claude.json:

{
  "mcpServers": {
    "redmine": {
      "transport": "sse",
      "url": "http://localhost:8000/sse"
    }
  }
}

Note: Environment variables (REDMINE_DOMAIN, REDMINE_API_KEY) are configured on the SSE server side, not in Claude Code.

Connecting VS Code (GitHub Copilot) to SSE Server

VS Code with GitHub Copilot can also connect to the SSE server. Edit the MCP configuration file:

macOS: ~/Library/Application Support/Code/User/mcp.json

Windows: %APPDATA%\Code\User\mcp.json

Linux: ~/.config/Code/User/mcp.json

Add the following configuration:

{
  "servers": {
    "redmine": {
      "type": "sse",
      "url": "http://localhost:8000/sse"
    }
  }
}

Reference: For more details on VS Code MCP configuration, see VS Code MCP Servers Documentation.

🔄 Updating/Reinstalling MCP

If you need to update to the latest version of the MCP server or reinstall it:

Quick Update (Recommended)

# Navigate to project directory
cd /path/to/redmine-mcp

# Pull latest changes (if from git)
git pull origin main

# Force reinstall with uv tool
uv tool install . --force --reinstall

# Restart Claude Code to reload MCP server

Full Reinstallation

If quick update doesn't work, follow these steps:

1. Remove Previous Installation

# Remove from Claude Code
claude mcp remove redmine

# Uninstall the package (if installed with uv tool)
uv tool uninstall redmine-mcp

# Or if installed with pip
pip uninstall redmine-mcp

2. Install Latest Version

# Navigate to project directory
cd /path/to/redmine-mcp

# Pull latest changes (if from git)
git pull origin main

# Install latest version
uv tool install .

# Or using pip
pip install .

3. Re-register with Claude Code

# Use full path to avoid PATH conflicts
claude mcp add redmine "$(which redmine-mcp)" \
  -e REDMINE_DOMAIN="https://your-redmine-domain.com" \
  -e REDMINE_API_KEY="your_api_key_here" \
  -e REDMINE_MCP_LOG_LEVEL="INFO" \
  -e REDMINE_MCP_TIMEOUT="30"

4. Verify Updated Installation

# Check installed version
uv tool list | grep redmine

# Verify MCP registration
claude mcp list

# Or check in Claude Code using slash command
# /mcp

Troubleshooting Update Issues

Problem: Old version still running after update

• This usually happens when PATH has multiple redmine-mcp executables

• Solution: Use full path in Claude Code MCP config

# Find the correct path
ls -la ~/.local/bin/redmine-mcp

# Update MCP config with full path
claude mcp remove redmine
claude mcp add redmine "/Users/YOUR_USERNAME/.local/bin/redmine-mcp" \
  -e REDMINE_DOMAIN="https://your-redmine-domain.com" \
  -e REDMINE_API_KEY="your_api_key_here"

Problem: "Failed to reconnect to redmine" after update

• Restart Claude Code completely (close and reopen)

• Or use /mcp command and select restart for redmine server

Important Notes:

• Always restart Claude Code after updating MCP server

• Use --force --reinstall flags to ensure clean installation

• Check tool count in /mcp to verify update (current: 26 tools)
