• Prereqs
  • Tidewave gem already mounted (e.g., /tidewave/mcp on http://localhost:3100).
  • Rails server running locally on that port (bin/rails s -p 3100 or equivalent).
• Install the shim globally
  1. Copy tidewave_mcp_stdio_proxy.rb into ~/bin/tidewave-mcp-cli-bridge (or any directory on your $PATH).
  2. Make it executable: chmod +x ~/bin/tidewave-mcp-cli-bridge.
  3. (Optional) If you need request logging, export TIDEWAVE_MCP_PROXY_LOG=/path/to/logfile.log. Leave it unset or set to off to disable logging.
• Configure Codex
  • Edit ~/.codex/config.toml and add:
