Sandbox MCP Server
Sandbox MCP server providing secure, isolated code execution environments for AI agents — running code in sandboxed containers to prevent unauthorized access to the host system, enabling agents to safely execute untrusted or generated code without security risk to the host machine.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Docker sandbox. Local. No credentials. Docker is not perfect isolation — use gVisor for higher security.
⚡ Reliability
Best When
An agent generates or receives code that needs to be executed securely — sandboxing prevents malicious or buggy code from affecting the host system.
Avoid When
You trust the code being executed or don't need isolation — direct execution is faster and simpler.
Use Cases
- • Executing AI-generated code safely in isolated environments from coding agents
- • Running untrusted code samples without risking host system compromise
- • Sandboxed testing of code snippets from development agents
- • Secure eval environments for code generation verification from QA agents
- • Multi-language code execution in isolation from polyglot agents
- • Safe execution of user-provided code in agent workflows
Not For
- • Production code execution with persistent state (containers are ephemeral)
- • High-performance computing — sandboxing adds overhead
- • Teams without Docker or container runtime
Interface
Authentication
No authentication — local Docker-based sandbox. Docker must be installed and running on the host system.
Pricing
Free community MCP. Docker required. No external service costs.
Agent Metadata
Known Gotchas
- ⚠ Docker must be installed and running — heavy dependency
- ⚠ Container startup latency (1-3 seconds) adds to every execution
- ⚠ Ephemeral containers lose state between calls — plan for stateless execution
- ⚠ Container resource limits must be configured to prevent resource exhaustion
- ⚠ Community MCP from simbianai — limited documentation
- ⚠ Escape vulnerabilities in Docker — use gVisor/Firecracker for highest security
