mcp redmine

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

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

• Access comprehensive Redmine API functionality

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

• Access to a Redmine instance
• Redmine API key

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