MCP Redmine

MCP Redmine

Status: Works great and is in daily use without any known bugs.

Status2: I just added the package to PyPI and updated the usage instructions. Please report any issues :)

Let Claude be your Redmine assistant! MCP Redmine connects Claude Desktop 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.

Usage with Claude Desktop

1. Installation using uv

Ensure you have uv installed.

Install uv if you haven't already.

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

Add to your claude_desktop_config.json:

2. Installation using docker

Ensure you have docker installed.

Build docker image:

Add to your claude_desktop_config.json:

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
