A side-by-side look at the Sandbox as a Service and E2b Sandbox MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Sandbox as a Service for code execution work over a hosted endpoint; choose E2b Sandbox MCP for code execution as a local process. You can also run both side by side in one mcpServers block.
AAS_API_KEY, AAS_BASE_URL.E2B_API_KEY, GITHUB_TOKEN.sandbox_create, sandbox_list, sandbox_info.Rows where the two servers differ are marked.
