1Create a Muse4AI key
Open Muse4AI › Settings › API & agent. Turn on the server and create an API key. Copy it now: the full key is shown only once. Keep Muse4AI running.
2Add Muse4AI to the agent
Open
~/.codex/config.toml. Merge the example into any existing configuration instead of replacing other servers. Replacemsk_YOUR_KEYwith your key, save, and reload the agent's MCP tools.~/.codex/config.toml [mcp_servers.muse4ai] url = "http://127.0.0.1:47821/mcp" [mcp_servers.muse4ai.http_headers] Authorization = "Bearer msk_YOUR_KEY"3Check the connection
Ask the agent: "Use Muse4AI to check status". Allow the
muse_statustool call if prompted. Check that the reply reports Muse4AI status, rather than guessing.
