MCP Redmine

Status: Works great, but still in beta

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.

Requirements

• Access to a Redmine instance
• Redmine API key
• Python 3.10+

The openapi specification used is for redmine 5.0, tested on Redmine 6.0.3, but will likely work with older versions as well.
