You can connect OpenAI's Codex CLI to Tidewave via its MCP support.
Install
Invoke the codex CLI to add tidewave using the HTTP transport:
$ codex mcp add tidewave --url http://localhost:$PORT/tidewave/mcp
Replace $PORT by 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.
