Redmine MCP

This is a custom MCP (Model Context Protocol) server that integrates with Redmine, allowing you to interact with your Redmine projects and issues through the Cline VS Code extension.

Prerequisites

• Node.js: You need Node.js (version 18 or newer) installed on your system.
• Redmine Instance: You need a running Redmine instance with the REST API enabled.
• Redmine API Key: You need an API key for your Redmine user account. You can find this in your Redmine account settings (usually under "My Account" -> "API access key").
• Cline: You need the Cline VS Code extension installed and configured.

Installation

1. Clone the repository:

   git clone https://github.com/ilask/Redmine-MCP.git
   cd Redmine-MCP

2. Install dependencies:

   npm install

Configuration

1. Set environment variables: Create a .env file in the root of the project directory and add the following, replacing the placeholders with your actual Redmine hostname and API key:

   REDMINE_HOST=your-redmine-host.com
   REDMINE_API_KEY=your-redmine-api-key

   Important: Do not commit your .env file to version control! It contains sensitive information. The .gitignore file included in this repository should prevent it from being committed.

Adding to Cline

1. Open Cline Settings: In VS Code, open the Cline extension and go to the MCP Server tab.
2. Edit MCP Settings: Click "Edit MCP Settings" to open the cline_mcp_settings.json file.

3. Add the server: Add the following entry to the mcpServers object, replacing the args path with the absolute path to the server.js file on your system:

   {
     "mcpServers": {
       "redmine-server": {
         "command": "node",
         "args": ["C:UsersyourusernamepathtoRedmine-MCPserver.js"],
         "disabled": false,
         "autoApprove": []
       }
     }
   }

   Important: Make sure to use double backslashes () in the path on Windows. 4. Save: Save the cline_mcp_settings.json file. Cline should automatically detect the changes and start the server.

Available Resources and Tools

Resources

• redmine://projects/{project_id}: This resource represents a Redmine project. Replace {project_id} with the actual ID of a project in your Redmine instance. You can use the access_mcp_resource tool in Cline to read the details of a project. For example:

  <access_mcp_resource>
  <server_name>redmine-server</server_name>
  <uri>redmine://projects/123</uri>
  </access_mcp_resource>

  (Replace 123 with a valid project ID). This will return the project details as JSON.

Tools

• create_issue: This tool allows you to create a new issue in Redmine. It takes the following parameters:

  • project_id (string, required): The ID of the project where the issue should be created.
  • subject (string, required): The subject of the issue.
  • description (string, required): The description of the issue.

  You can use the use_mcp_tool tool in Cline to call this tool. For example:

  <use_mcp_tool>
  <server_name>redmine-server</server_name>
  <tool_name>create_issue</tool_name>
  <arguments>
  {
    "project_id": "456",
    "subject": "My New Issue",
    "description": "This is a test issue created via Cline."
  }
  </arguments>
  </use_mcp_tool>

  (Replace 456 with a valid project ID). This will create a new issue in the specified project and return the issue details as JSON.

Troubleshooting

• Connection closed error: If you see an error like "MCP error -1: Connection closed", make sure that your REDMINE_HOST and REDMINE_API_KEY environment variables are correctly set. Also, ensure that your Redmine instance is accessible from your computer.
• Check server logs: If you encounter issues, check the server's output in the VS Code terminal for any error messages. The server logs errors to the console.
