Install KnowBe4 in Codex

What you need first

• Codex, installed.
• Docker, which gives the docker command the server starts with.
• Your own value for YOUR_KNOWBE4_API_KEY.

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 knowbe4-mcp --env KNOWBE4_API_KEY=YOUR_KNOWBE4_API_KEY -- docker run -i --rm -e KNOWBE4_API_KEY ghcr.io/wyre-ai/knowbe4-mcp:v1.1.6

2. Replace YOUR_KNOWBE4_API_KEY with your own value.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of knowbe4-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Codex.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
