SandboxAPI MCP Server

Give your AI agent the ability to execute code in 8 programming languages, safely.

SandboxAPI MCP Server connects any MCP-compatible AI client (Claude, Cursor, VS Code, Windsurf, etc.) to secure code execution. Every execution runs inside a gVisor-sandboxed Docker container with no network access, strict resource limits, and ephemeral filesystems.

Quick Start

Option 1: Remote Server (No Setup)

Connect directly to the hosted endpoint. No local installation required.

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "sandboxapi": {
      "url": "https://mcp.sandboxapi.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "sandboxapi": {
      "url": "https://mcp.sandboxapi.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "sandboxapi": {
      "url": "https://mcp.sandboxapi.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
Option 2: Docker
docker run -d \
  -p 8081:8081 \
  -e SANDBOXAPI_API_KEY=your_sandboxapi_key \
  -e MCP_API_KEY=your_mcp_auth_key \
  sandboxapi/mcp:latest

Then point your client to http://localhost:8081/mcp.

Option 3: Build from Source
git clone https://github.com/sandboxapi/sandboxapi-mcp.git
cd sandboxapi-mcp
go build -o sandboxapi-mcp .

export SANDBOXAPI_API_KEY=your_key
export MCP_API_KEY=optional_auth_key
./sandboxapi-mcp

Available Tools

execute_code

Execute code in a sandboxed container.

ParameterTypeRequiredDescription

Environment Variables

VariableRequiredDescription
SANDBOXAPI_API_KEYYesAPI key for the SandboxAPI backend
MCP_API_KEYNoAuth key for the MCP endpoint (omit for open access)
MCP_PORTNoPort to listen on (default: 8081)
SANDBOXAPI_URLNoAPI base URL (default: https://api.sandboxapi.dev)

Security

Every code execution is isolated with defense-in-depth:

  • gVisor (runsc) — User-space kernel intercepts all syscalls
  • Network isolation — Executed code cannot make outbound connections
  • Resource limits — CPU, memory, and disk usage are capped
  • Ephemeral containers — Destroyed immediately after execution
  • Read-only filesystem — No persistent writes between executions
  • Code size limits — Source code capped at 1MB
  • Timeout enforcement — Hard kill after configured timeout

Questions fréquentes

Qu'est-ce que SandboxAPI ?

Execute code in 8 languages (Python, JS, TS, Go, Java, C++, C, Bash) in gVisor sandboxes.

Comment installer SandboxAPI ?

Il fonctionne comme serveur distant. Dans Claude Code : claude mcp add --transport http sandboxapi 'https://mcp.sandboxapi.dev/mcp'. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.

Faut-il une clé API pour SandboxAPI ?

Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.

SandboxAPI est-il open source ?

Oui. Son code est sur GitHub sous licence MIT.

Qui maintient SandboxAPI ?

Il est publié par sandboxapi. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
