Connects Claude and other MCP clients to SandboxAPI's gVisor-backed code execution environment. Exposes three tools: execute_code for single runs, execute_batch for multiple isolated executions, and list_languages for runtime info. Supports Python, JavaScript, TypeScript, Go, Java, C++, C, and Bash with configurable timeouts and stdin. Every execution runs in an ephemeral container with no network access and strict resource limits. Ships as a hosted endpoint at mcp.sandboxapi.dev requiring only an API key, or self-host via Docker or Go binary. Reach for this when you need AI-assisted code generation with immediate, safe execution feedback across multiple languages without spinning up local runtimes.
