Cosmik vs Server Everything
A side-by-side look at the Cosmik and Server Everything MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Cosmik for aerospace & astrodynamics work over a hosted endpoint; choose Server Everything for other tools and integrations as a local process. You can also run both side by side in one mcpServers block.
