MCP Redmine Enhanced (Active Fork)

Fork Notice: This is an active fork of runekaagaard/mcp-redmine maintained to ensure stability and availability when upstream development is limited.

Enhanced Features

This fork adds several powerful enhancements over the original:

• 🎯 Advanced Response Filtering: Intelligent filtering with preset configurations (minimal, clean, essential_issues)
• 📝 Journal Filtering: Filter code-related entries from issue journals for cleaner output
• 🔒 Enhanced Security: ReDoS protection and comprehensive input validation
• ⚡ MCP Capabilities: Dynamic capability reporting based on API paths
• 🧪 Comprehensive Testing: 106+ tests covering security and edge cases
• 🚀 Automated Publication: Complete PyPI publication workflow with pre-checks

Core Functionality

Let Claude be your Redmine assistant! MCP Redmine connects your MCP client to your Redmine instance, allowing it to:

• Search and browse projects and issues
• Create and update issues with full markdown support
• Upload and download file attachments
• Manage and track time entries
• Update issue statuses and fields
• Access comprehensive Redmine API functionality

Uses httpx for API requests and integrates with the Redmine OpenAPI specification for comprehensive API coverage.

Installation

Option 1: Using uvx (Recommended)

The easiest way to install MCP Redmine Enhanced:

{
  "mcpServers": {
    "redmine": {
      "command": "uvx",
      "args": [
        "--from", "mcp-redmine-enhanced==2025.09.13.162715.post0",
        "--refresh-package", "mcp-redmine-enhanced",
        "mcp-redmine"
      ],
      "env": {
        "REDMINE_URL": "https://your-redmine-instance.example.com",
        "REDMINE_API_KEY": "your-api-key",
        "REDMINE_REQUEST_INSTRUCTIONS": "/path/to/instructions.md"
      }
    }
  }
}

Prerequisites: Install uv if you don't have it:

• Linux/macOS: curl -LsSf https://astral.sh/uv/install.sh | sh
• macOS (Homebrew): brew install uv
• Windows: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Option 2: Using pip

If you prefer using pip, first install the package globally:

pip install mcp-redmine-enhanced

Then configure Claude Desktop:

{
  "mcpServers": {
    "redmine": {
      "command": "mcp-redmine",
      "env": {
        "REDMINE_URL": "https://your-redmine-instance.example.com",
        "REDMINE_API_KEY": "your-api-key",
        "REDMINE_REQUEST_INSTRUCTIONS": "/path/to/instructions.md"
      }
    }
  }
}

Option 3: Development from Git

For the latest features and automatic updates:

{
  "mcpServers": {
    "redmine": {
      "command": "uvx",
      "args": [
        "--from", "git+https://github.com/olssonsten/mcp-redmine.git",
        "--refresh-package", "mcp-redmine-enhanced",
        "mcp-redmine"
      ],
      "env": {
        "REDMINE_URL": "https://your-redmine-instance.example.com",
        "REDMINE_API_KEY": "your-api-key",
        "REDMINE_REQUEST_INSTRUCTIONS": "/path/to/instructions.md"
      }
    }
  }
}

Package Details:

• PyPI Package: mcp-redmine-enhanced
• Console Script: mcp-redmine (for compatibility)
• Latest Version: 2025.09.13.140055.post0
• Repository: https://github.com/olssonsten/mcp-redmine

For developers who want to contribute or modify the code, clone the repository and use the local development setup described in Option 3 above.

Alternative: Docker Installation

If you prefer using Docker:

1. Build Docker Image

   git clone https://github.com/olssonsten/mcp-redmine.git
   cd mcp-redmine
   docker build -t mcp-redmine-enhanced .

2. Configure Claude Desktop

   {
     "mcpServers": {
       "redmine": {
         "command": "docker",
         "args": [
           "run", "-i", "--rm",
           "-e", "REDMINE_URL",
           "-e", "REDMINE_API_KEY",
           "-e", "REDMINE_REQUEST_INSTRUCTIONS",
           "-v", "/path/to/instructions.md:/app/INSTRUCTIONS.md",
           "mcp-redmine-enhanced"
         ],
         "env": {
           "REDMINE_URL": "https://your-redmine-instance.example.com",
           "REDMINE_API_KEY": "your-api-key",
           "REDMINE_REQUEST_INSTRUCTIONS": "/app/INSTRUCTIONS.md"
         }
       }
     }
   }

Note: When using Docker, the REDMINE_REQUEST_INSTRUCTIONS environment variable must point to a path inside the container. Mount your local instruction file into the container at the correct location.

Environment Variables

• REDMINE_URL: URL of your Redmine instance (required)
• REDMINE_API_KEY: Your Redmine API key (required, see below for how to get it)
• REDMINE_REQUEST_INSTRUCTIONS: Path to a file containing additional instructions for the redmine_request tool (optional). I've found it works great to have the LLM generate that file after a session. (example1 example2)

Note: When running via Docker, the REDMINE_REQUEST_INSTRUCTIONS environment variable must point to a path inside the container, not a path on the host machine.
Therefore, if you want to use a local file, you need to mount it into the container at the correct location.

Getting Your Redmine API Key

1. Log in to your Redmine instance
2. Go to "My account" (typically found in the top-right menu)
3. On the right side of the page, you should see "API access key"
4. Click "Show" to view your existing key or "Generate" to create a new one
5. Copy this key for use in your configuration

Examples

Creating a new issue

Let's create a new bug report in the "Website" project:

1. Title: "Homepage not loading on mobile devices"
2. Description: "When accessing the homepage from iOS or Android devices, the loading spinner appears but the content never loads. This issue started after the last deployment."
3. Priority: High
4. Assign to: John Smith

Searching for issues

Can you find all high priority issues in the "Website" project that are currently unassigned?

Updating issue status

Please mark issue #123 as "In Progress" and add a comment: "I've started working on this issue. Expect it to be completed by Friday."

Logging time

Log 3.5 hours against issue #456 for "Implementing user authentication" done today.

Using Response Filtering (New)

Get issues with reduced verbosity:
redmine_request("/issues.json", params={"limit": 5}, mcp_filter={"remove_empty": True, "remove_custom_fields": True})

Use preset for clean responses:
redmine_request("/issues.json", mcp_filter="clean")
Filter journals for code reviews:
redmine_request("/issues/123.json", params={"include": "journals"}, mcp_filter={"journals": {"code_review_only": True}})
