A side-by-side look at the A11y Check and Sandbox as a Service MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose A11y Check for browser automation work over a hosted endpoint; choose Sandbox as a Service for code execution over a hosted endpoint. You can also run both side by side in one mcpServers block.
AAS_API_KEY, AAS_BASE_URL.Rows where the two servers differ are marked.
