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.

          "REDMINE_ALLOWED_DIRECTORIES": "/tmp,/home/user/uploads"
        }
      }
    }
  }

2. Installation using `docker`

Ensure you have docker installed.

docker --version

Build docker image:

git clone git@github.com:runekaagaard/mcp-redmine.git
cd mcp-redmine
docker build -t mcp-redmine .

Add to your claude_desktop_config.json:

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

Environment Variables

Variable	Required	Default	Description
`REDMINE_URL`	Yes	-	URL of your Redmine instance. Subpaths are supported (e.g., `http://localhost/redmine/`)
`REDMINE_API_KEY`	Yes	-	Your Redmine API key (see below for how to get it)
`REDMINE_REQUEST_INSTRUCTIONS`	No	-	Path to a file containing additional instructions for the redmine_request tool. I've found it works great to have the LLM generate that file after a session. (example1 example2)
`REDMINE_HEADERS`	No	(empty)	Custom HTTP headers to include in all requests. Format: `"Header1: Value1, Header2: Value2"`. Useful for proxies that require additional authentication (e.g., `X-Redmine-Username`)
`REDMINE_RESPONSE_FORMAT`	No	`yaml`	Response format: `yaml` or `json`. Controls how API responses are formatted
`REDMINE_ALLOWED_DIRECTORIES`	For upload/download	(disabled)	Required for file operations. Comma-separated list of directories where upload/download are allowed (e.g., `/tmp,/home/user/uploads`). Upload/download are disabled if not set for security
`REDMINE_DANGEROUSLY_ACCEPT_INVALID_CERTS`	No	(disabled)	Set to `1` to disable SSL certificate verification. Use only for self-signed certs in trusted environments

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.

Security Note: The REDMINE_ALLOWED_DIRECTORIES setting protects against path traversal attacks. Paths containing ../ are resolved before validation, ensuring files can only be accessed within the allowed directories.

Getting Your Redmine API Key

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