cd mcp-gradle-tomcat
npm install

Quick Start

1. Add to Claude Configuration

Add this to your Claude configuration file (~/.claude/config.json):

{
  "mcpServers": {
    "gradle-tomcat": {
      "command": "mcp-gradle-tomcat",
      "env": {
        "GRADLE_WORKING_DIR": "/path/to/your/gradle/project"
      }
    }
  }
}

2. Use with Claude

Once configured, you can use these commands in Claude:

• "Start Tomcat" - Launches your Gradle application
• "Stop Tomcat" - Gracefully stops the running application
• "Get Tomcat status" - Shows process status and uptime
• "Get recent logs" - Retrieves application logs with filtering
• "Restart Tomcat" - Stops and starts the application
