ETL: Connect OpenAI Codex to MCP - Integrate.io

Codex speaks MCP over stdio, so it uses the mcp-remote bridge to reach the remote HTTP endpoint. For token detail, see Authentication. The endpoint is: https://api.xplenty.com/YOUR_ACCOUNT_ID/api/mcp Replace YOUR_ACCOUNT_ID with your account subdomain or numeric id (the value in your dashboard URL). Add the server to ~/.codex/config.toml:

[mcp_servers.integrateio]
command = "npx"
args = [
  "-y",
  "mcp-remote",
  "https://api.xplenty.com/YOUR_ACCOUNT_ID/api/mcp",
  "--header",
  "Authorization: Bearer YOUR_ACCESS_TOKEN"
]

Replace YOUR_ACCOUNT_ID with your account subdomain or numeric id and YOUR_ACCESS_TOKEN with a Personal Access Token (see Authentication), then restart Codex.

If you omit the --header line, mcp-remote falls back to OAuth browser sign-in instead of a static token, the same flow Claude Code uses. A Personal Access Token is the simpler choice for an always-on CLI because it does not expire after a couple of hours.

Verify

Restart Codex and confirm the integrateio tools are listed. Trouble connecting? See Troubleshooting.
