#   chmod +x ocp-connect

ocp-connect — Connect this machine to a remote OCP (Open Claude Proxy)

Configures OPENAI_BASE_URL and OPENAI_API_KEY in your shell rc file
so tools like Claude Code, Cline, Aider, etc. point to the remote OCP.

Usage:
  ocp-connect <host-ip> [options]

Options:
  --port PORT      Port OCP listens on (default: 3456)
  --key  API_KEY   API key (prompted interactively if remote requires auth)
  --version        Print version and exit
  --help, -h       Show this help

Examples:
  ocp-connect 192.168.1.10
  ocp-connect 192.168.1.10 --port 8080
  ocp-connect 192.168.1.10 --key ocp_abc123

What it does:
  1. Tests connectivity to the remote OCP
  2. Verifies your API key (if auth is enabled)
  3. Writes OPENAI_BASE_URL and OPENAI_API_KEY to ~/.bashrc or ~/.zshrc
  4. Sets system-level env vars (launchctl on macOS, systemd on Linux)
  5. Configures OpenClaw automatically; prints setup hints for other IDEs
     (Cline, Continue.dev, Cursor — manual configuration required)
  6. Runs a smoke test to confirm everything works

After running, reload your shell:  source ~/.bashrc  (or ~/.zshrc)
