A side-by-side look at the Sonicake Pocket Master and Ugs MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Sonicake Pocket Master for embedded system work as a local process; choose Ugs MCP for embedded system as a local process. You can also run both side by side in one mcpServers block.
