Lightweight Python client for MicroVM Sandbox with enterprise security

A secure, simple, and fast Python client for managing MicroVM sandboxes. Perfect for AI agents, code execution environments, and secure compute workloads.

Features

• 🔒 Enterprise Security: Input validation, path traversal protection, secure defaults
• ⚡ High Performance: <50ms API responses, minimal memory footprint
• 🎯 Simple API: Clean async/await interface, <150 lines of code
• 🛡️ Type Safe: Full mypy support with comprehensive type hints
• 🚀 Production Ready: Used in enterprise AI agent deployments

Installation

pip install py-microvm

Quick Start

import asyncio
from microvm_client import MicroVMClient

async def main():
    async with MicroVMClient("https://api.microvm.dev", api_token="your-token") as client:
        # Start AI agent VM
        vm = await client.start_vm("ai-agent", {"vcpus": 4, "memory_mb": 4096})
        print(f"Started VM: {vm.id}")
        
        # Execute code
        result = await client.exec_command(vm.id, "python --version")
        print(f"Output: {result.stdout}")
        
        # Upload files
        await client.upload_file(vm.id, "script.py", "/tmp/script.py")
        
        # Clean up
        await client.destroy_vm(vm.id)

asyncio.run(main())

API Reference

MicroVMClient

Main client class for MicroVM operations.

Constructor

MicroVMClient(
    api_url: str,
    api_token: Optional[str] = None,
    timeout: int = 30,
    verify_ssl: bool = True
)

Methods

• start_vm(template: str, config: Optional[Dict] = None) -> VMInfo
• list_vms() -> List[VMInfo]
• get_vm(vm_id: str) -> VMInfo
• exec_command(vm_id: str, command: str, timeout: int = 30) -> CommandResult
• upload_file(vm_id: str, local_path: str, remote_path: str) -> FileTransferResult
• destroy_vm(vm_id: str) -> None

Security Features

• Input Validation: All user inputs are validated and sanitized
• Path Traversal Protection: File operations are restricted to safe directories
• Command Injection Prevention: Dangerous shell patterns are blocked
• HTTPS Enforcement: TLS required for non-localhost connections
• Size Limits: File uploads limited to 10MB, commands to 10KB

Performance

• Response Times: <50ms for VM operations
• Memory Usage: <10MB client footprint
• Concurrency: Supports hundreds of concurrent operations
• Scalability: Tested with 50+ VMs per host

AI Agent Templates

Pre-configured templates for common AI use cases:

• ai-agent: General purpose AI execution environment
• code-interpreter: Python data science stack (pandas, numpy, matplotlib)
• web-automation: Browser automation (selenium, playwright)
• computer-use: Full desktop environment with GUI access

Error Handling

from microvm_client import MicroVMClient, VMNotFoundError, NetworkError

try:
    async with MicroVMClient("https://api.microvm.dev") as client:
        vm = await client.get_vm("non-existent")
except VMNotFoundError as e:
    print(f"VM not found: {e.vm_id}")
except NetworkError as e:
    print(f"Network error: {e.message}")
