How do I install CTX?
- 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/halloffame12/CTX
- Add it to Claude Code. Replace the part after -- with the command from the README. Remote servers use --transport http with a URL.
claude mcp add ctx -- <command from README> claude mcp add --transport http ctx <server-url>
- Check it connected. This lists your MCP servers and their status.
claude mcp list
Or ask Claude to set it up
Paste this into Claude Code and it installs CTX for you:
Add the "CTX" MCP server from https://github.com/halloffame12/CTX to Claude Code. Read its README for the launch command and any API keys I need, run claude mcp add, then check that it connects.
