SwarmTask - Async Task Manager with MCP

A powerful MCP (Model Context Protocol) server that enables parallel execution of shell commands through AI assistants like Claude Code. SwarmTask allows you to submit multiple tasks (system commands, scripts, builds, tests) that run simultaneously in Go goroutines, giving you real-time progress monitoring and results.

Perfect for:

• 🔧 System Administration: Run multiple diagnostic commands in parallel
• 🏗️ Development Workflows: Execute builds, tests, and deployments simultaneously
• 📊 Data Processing: Process multiple files or datasets concurrently
• 🌐 Network Operations: Parallel connectivity tests and monitoring
• 🔍 Monitoring & Auditing: Simultaneous system health checks

⚠️ Security Note: Script injection protection and security ring-fencing are not implemented in this release. SwarmTask executes commands with the same privileges as the running process. Planned for next release.

Features

• 🚀 Async Task Execution - Submit tasks and get immediate batch ID
• ⚡ Goroutine-based Processing - Parallel task execution with channels
• 📊 Real-time Status Tracking - Poll for progress and results
• 🔗 MCP Protocol Compliant - Integrates with Claude Code via supergateway
• 📈 Progress Notifications - Streaming updates during execution

Quick Start

1. Start the server:

./swarmtask --port 3500

2. Configure Claude Code - Add to ~/.claude/mcp_servers.json:

{
  "mcpServers": {
    "swarmtask": {
      "command": "npx",
      "args": [
        "-y",
        "supergateway", 
        "--streamableHttp",
        "http://localhost:3500/mcp"
      ],
      "env": {}
    }
  }
}

3. Restart Claude Code to load the MCP server

Available Tools

submit_tasks

Submit multiple tasks for parallel asynchronous execution.

Input Format: JSON string mapping task names to shell commands

Correct Usage:

{
  "tasks": "{\"list_home\":\"ls ~\",\"ping_test\":\"ping -c 4 google.com\",\"disk_usage\":\"df -h\"}"
}

Alternative Format (easier to read):

{
  "tasks": {
    "list_home": "ls ~",
    "ping_test": "ping -c 4 google.com", 
    "disk_usage": "df -h",
    "system_info": "uname -a"
  }
}

Key Points:

• Task names become part of the task ID: {batch_id}-{task_name}
• Commands are executed as shell commands (sh -c "command")
• All tasks run in parallel goroutines
• Maximum 50 tasks per batch
• Returns immediately with batch_id for tracking

Returns:

📈 Overall Progress: 75.0%
🔄 Status: running

📋 Task Details:

✅ list_home:
   Command: ls ~
   Results: Desktop Documents Downloads...

🔄 ping_test:
   Command: ping -c 4 google.com
   Results: running

✅ disk_usage:
   Command: df -h
   Results: Filesystem Size Used Avail...

❌ system_info:
   Command: uname -a

Architecture

Core Components

• MCP Server (cmd/swarmtask/main.go)

  • HTTP transport on configurable port (default 3500)
  • Handles submit_tasks and check_status MCP tools
  • Input validation and error handling
  • Returns immediate responses with batch IDs

• Task Manager (internal/core/manager.go)

  • Master Worker: Coordinates batch execution
  • Sub Workers: Execute individual tasks in goroutines
  • Global State: Thread-safe task storage with mutexes
  • Channel Communication: Results flow back via channels

• Logging System (internal/logger/)

  • Asynchronous file logging with rotation (5MB)
  • HTTP request/response logging
  • Task execution tracking with timing
  • Environment configurable (STLOGDIR)

Data Flow

1. Submit: Client sends JSON tasks → Batch created → Goroutines started
2. Execute: Tasks run in parallel → Results stored in global maps
3. Monitor: Status checks return real-time progress → Non-blocking lookups
4. Complete: All tasks finish → Final results available

Key Features

• Parallel Execution: Multiple tasks run simultaneously in goroutines
• Non-blocking: Immediate response with batch tracking
• Thread-safe: Global maps protected with RWMutex
• Real-time Status: Progress tracking with completion percentage
• Error Resilience: Individual task failures don't affect others

Usage Examples

Basic Parallel Execution

1. Submit multiple system tasks:

Submit tasks: {"sys_info":"uname -a", "disk_space":"df -h", "memory":"free -h", "processes":"ps aux | head -10"}

2. Monitor progress:

Check status with batch_id: a1b2c3d4-e5f6-7890

3. View results:

📊 Progress: 100% | ✅✅✅✅ All tasks completed

Long-running Tasks

Submit tasks: {"backup":"tar -czf backup.tar.gz ~/Documents", "network_test":"ping -c 100 google.com", "file_scan":"find /var/log -name '*.log' -size +1M"}

Development Workflow

Submit tasks: {"git_status":"git status", "run_tests":"npm test", "build":"npm run build", "lint":"npm run lint"}

Tasks execute in parallel goroutines while you receive real-time status updates!
