Install C64 Bridge in Codex

What you need first

• Codex, installed.
• Node.js, which gives the npx command the server starts with.

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 c64bridge -- npx -y [email protected]

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

Check it worked

Ask Codex: List the tools of c64bridge.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Codex sees. Install it, or write the full path of npx in the config.
