A side-by-side look at the Tenki Sandbox MCP and PRIMS MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Tenki Sandbox MCP for code execution work as a local process; choose PRIMS for code execution over a hosted endpoint. You can also run both side by side in one mcpServers block.
TENKI_API_KEY, TENKI_AUTH_TOKEN.run_code, list_dir, preview_file.Rows where the two servers differ are marked.
