How do I install 4DA?
- Find the launch command. The README says how the server starts (npx, uvx, docker or a remote URL) and which API keys it needs.
https://github.com/4DA-Systems/4DA/tree/main/mcp-4da-server
- Add it to Claude Code. Replace the part after -- with the command from the README. Remote servers use --transport http with a URL.
