You can use Tidewave with OpenAI's Codex CLI

Installation

First, you must install a mcp-proxy.

$ codex mcp add tidewave /path/to/mcp-proxy http://localhost:$PORT/tidewave/mcp

Where $PORT is the port your web application is running on. And you are good to go!

Verify

Running codex mcp list will show you the config is there, but won't verify the connection. You can verify the MCP connection is working by starting Codex and running the /mcp command. If it's connected, you should see the list of Tidewave tools. If not, check out our MCP Troubleshooting guide.
