Asynchronous MCP wrapper for Claude Code CLI

Claude Code MCP Async Server

Asynchronous MCP wrapper for Claude Code CLI

Enable Claude Code to spawn child Claude Code sessions for parallel task execution.

Features

• ✅ Async execution - Start tasks in background, continue working
• ✅ Multi-instance parallelism - Run multiple Claude Code sessions simultaneously
• ✅ Automatic cleanup - No zombie processes
• ✅ Zero config - Works out of the box

Quick Start

🚀 Install with UVX

Zero configuration - just run:

uvx claudecode-mcp-async

Configure Claude Code

Add to your ~/.claude/settings.json:

{
  "mcpServers": {
    "claude-code-mcp": {
      "command": "uvx",
      "args": ["claudecode-mcp-async"],
      "env": {}
    }
  }
}

Restart Claude Code

Reload or restart Claude Code to load the MCP server.

Usage Examples

🚀 Async Execution (Game Changer!)

Start a long task and continue working immediately:

You:

Please analyze the entire project code and generate a comprehensive technical report

Claude: I'll analyze your entire project and generate a technical report. This is a large task, so I'll start it asynchronously...

✅ Task Started (Task ID: abc12345) You can continue working on other things while it runs in the background!

You: (Continue working immediately)

While the report is generating, help me write some unit tests

Claude: Sure! Let me write those unit tests for you...

You: (A few minutes later)

Can you check if the report task is finished?

Claude: ✅ Report Complete!

• Project structure analysis
• Code quality assessment
• Performance optimization recommendations
• Security audit results

⚡ Parallel Execution

Run multiple tasks simultaneously:

You:

I need to do three things at once:

1. Generate unit tests for utils.py
2. Refactor database.py to use async/await
3. Add type hints to all functions in api.py

Claude: I'll start all three tasks in parallel!

🔄 Task 1 Started (Task ID: task1) - Generating unit tests 🔄 Task 2 Started (Task ID: task2) - Refactoring database code 🔄 Task 3 Started (Task ID: task3) - Adding type hints

All tasks are running in parallel...

You: (Later)

Are all three tasks finished?

Claude: ✅ All Complete!

• ✅ Task 1: Unit tests for utils.py generated
• ✅ Task 2: database.py refactored to async mode
• ✅ Task 3: Type hints added to api.py functions

🎯 Quick Sync Tasks

For simple immediate tasks:

You:

Write a Python function to validate email addresses

Claude:

import re

def validate_email(email):
    pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'
    return re.match(pattern, email) is not None

# Usage examples
print(validate_email("[e-mail]"))  # True
print(validate_email("invalid-email"))    # False

✅ Task Complete!

Why Async?

Problem: Claude Code blocks the parent session while running.

Solution: This MCP server spawns child Claude Code processes that run in the background.

Benefits:

• 🚀 Start a task and continue working immediately
• ⚡ Run multiple tasks in parallel
• 🎯 No blocking, no waiting
• 🧹 Automatic process cleanup

Troubleshooting

Server not showing up?

• Use absolute path in config
• Run: chmod +x claudecode_mcp_async_server.py
• Restart Claude Code

Task stuck in "running"?

• Wait a moment, large tasks take time
• Check: ls -la /tmp/claude_code_tasks/
• View logs: tail -f /tmp/claude_code_mcp_debug.log

Requirements

• Python 3.6+
• Claude Code CLI installed
