Sandbox as a Service vs Edict
A side-by-side look at the Sandbox as a Service and Edict 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 Edict for code execution as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Sandbox as a Service when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a remote HTTP/SSE transport.
- You have the keys it needs:
AAS_API_KEY, AAS_BASE_URL.
Choose Edict when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
edict_schema, edict_version, edict_examples.

Frequently asked questions
Sandbox as a Service is categorized under Code Execution and uses a remote HTTP/SSE transport. Edict belongs to Code Execution and uses a local stdio subprocess. Pick Sandbox as a Service for code execution work and Edict for code execution.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Sandbox as a Service has no declared pricing — check the project's own site. Edict is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add sandbox-as-a-service and sowiedu-edict as separate keys in the same mcpServers object, and your assistant will call tools from either one.
