Install Mode VC LLM Token Economics & Model Release Velocity in Codex

What you need first

• Codex, installed.
• Nothing else: the server runs on its publisher's machines and Codex connects to it.

Steps

1. Run this in a terminal. It writes the server into ~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.

codex mcp add llm-economics --url https://modevc.com/api/mcp/llm-economics

2. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of llm-economics.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Codex asks.
