Installing Packages

const result = await client.callTool('sandbox_execute', {
  language: 'python',
  packages: ['beautifulsoup4', 'lxml'],
  code: `
from bs4 import BeautifulSoup
html = "<h1>Hello</h1>"
soup = BeautifulSoup(html, 'lxml')

  `
});

​
Security

Isolation: All sandbox executions run in isolated environments with:
  • No network access (except allowlisted domains)
  • No persistent storage
  • Memory and CPU limits
  • Automatic termination on timeout

​
Use Cases

  • Code execution — Run user-submitted code safely
  • Data analysis — Process data with Python libraries
  • Prototyping — Test code snippets quickly
  • Agent tools — Give agents code execution capability
