Install @coretext-ai/gerson-org-linear-90f54a3e-7920-4c3e-9ffd-fdff170d1458 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 gerson-org-linear-60x5gq -- npx -y @coretext-ai/gerson-org-linear-90f54a3e-7920-4c3e-9ffd-fdff170d1458

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

Check it worked

Ask Codex: List the tools of gerson-org-linear-60x5gq.

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.
