Status: Actively maintained and in daily use. Tested releases are published to PyPI with git tags, and issues and pull requests are triaged regularly.

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.

MCP Redmine works with any MCP client (Claude Code, Cursor, IntelliJ-based IDEs, n8n, etc.) - point your client at the same command and environment variables as above, following your client's documentation for registering MCP servers.

By default the server speaks stdio. For clients or setups that connect over HTTP, start the server with one of the HTTP transports:

# Recommended HTTP transport (serves on http://HOST:PORT/mcp)
mcp-redmine --transport streamable-http --host 0.0.0.0 --port 8000

# Legacy SSE transport, for older clients (serves on http://HOST:PORT/sse)
mcp-redmine --transport sse --host 0.0.0.0 --port 8000

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.

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

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

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."

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