How do I install ctxfile?
- 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/ctxfile/ctxfile
- Add it to Claude Code. Replace the part after -- with the command from the README. Remote servers use --transport http with a URL.
