Codex Setup

[dream-digital-marketing]

thanks @czlonkowski for building!

This is how I got it to work for Codex:

[mcp_servers.n8n]
command = "C:\Users\YOURUSERNAME\AppData\Roaming\npm\npx.cmd"
args = ["n8n-mcp"]
env = { "MCP_MODE" = "stdio", "LOG_LEVEL" = "error", "DISABLE_CONSOLE_OUTPUT" = "true", "N8N_API_URL" = "https://your-n8n-instance.com", "N8N_API_KEY" = "your-api-key" }
startup_timeout_sec = 40

Not sure if this is just my WindowsOS quirk but I had to specify that path to the npx.cmd. Instead of just
command = "npx". Even though it was in PATH, Codex couldn't find it.

I added the startup_timeout_sec = 40 just in case it took a while, it might take a little longer the first time spinning up.
