Codex Setup

Connect n8n-MCP to Codex for enhanced n8n workflow development.

Update your Codex configuration

Go to your Codex settings at ~/.codex/config.toml and add the following configuration:

Basic configuration (documentation tools only):

[mcp_servers.n8n]
command = "npx"
args = ["n8n-mcp"]
env = { "MCP_MODE" = "stdio", "LOG_LEVEL" = "error", "DISABLE_CONSOLE_OUTPUT" = "true" }

Full configuration (with n8n management tools):

[mcp_servers.n8n]
command = "npx"
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" }

Make sure to replace https://your-n8n-instance.com with your actual n8n URL and your-api-key with your n8n API key.

Managing Your MCP Server

Enter the Codex CLI and use the /mcp command to see server status and available tools.
