Usage with Claude

⚠️ Note: Currently, the server may crash in the Claude app due to high load. Improvements are under consideration.

To use this server with Claude, configure it as follows:

{
  "mcp-server-redmine": {
    "command": "npx",
    "args": [
      "-y",
      "--prefix",
      "/path/to/mcp-server-redmine",
      "mcp-server-redmine"
    ],
    "env": {
      "REDMINE_HOST": "https://your-redmine.example.com",
      "REDMINE_API_KEY": "your-api-key-here"
    }
  }
}

Configuration Options

• command: Command to execute the npm package
• args:
  • -y: Auto-respond "yes" to prompts
  • --prefix: Specify installation directory
  • Last argument specifies the package name
• env: Environment variables
  • REDMINE_HOST: Redmine server URL
  • REDMINE_API_KEY: Your Redmine API key
