Connect Codex to LazyFrog

The Codex command line. Signing in to Codex works with a free ChatGPT account, with limited usage.

First you'll need a LazyFrog account. Start free. Already have one? Carry on.

Step 1
Run the first command below in a terminal to add LazyFrog to Codex.
Step 2
Run the second command to sign in. A browser opens: sign in with your LazyFrog account and choose Allow.
Step 3
Start Codex and say what you'd like to make. Codex asks before it uses each LazyFrog tool, so choose to approve when asked.
Step 4
Signing in from another machine (over SSH, say)? Your browser sends the sign-in back to 127.0.0.1 on the machine running Codex, so it never arrives. Forward that port with SSH, or copy the full address the browser ends on (it starts with http://127.0.0.1) and open it on the machine running Codex, for example with curl.

Terminal

codex mcp add lazyfrog --url https://mcp.lazyfrog.dev/mcp
codex mcp login lazyfrog

If you run Codex without a person at the keyboard (codex exec), set its approval settings so LazyFrog's tools can run; otherwise Codex refuses the ones that change things.
You can take access away at any time in the portal, under Connected AIs.
You use your own AI plan. LazyFrog never charges for your AI's work.

Writing an MCP server of your own? Host it on LazyFrog: a real one, built and published by Codex in two messages.
