Connect Codex to Reloop
Add the Reloop MCP server to the Codex CLI and IDE extension, and sign in with your Reloop account.
Codex is OpenAI's coding agent for the terminal and IDE. The CLI and the IDE extension share one config file, so you set up Reloop once for both.
Prerequisites
- The Codex CLI or IDE extension installed
- A Reloop account
- A verified domain if you want to send email
Setup
Add the server
Add this to ~/.codex/config.toml:
[mcp_servers.reloop]
url = "https://reloop.sh/mcp"Sign in
Run the login command:
codex mcp login reloopYour browser opens the Reloop sign-in page. Sign in, choose the organization Codex can access, and approve.
Verify it works
Run codex mcp list and check that reloop is listed. In a Codex session, run /mcp to see its tools. Then ask something read-only:
"List my Reloop domains and tell me which ones are verified."
Example prompts
- "Create a campaign for our product launch announcement."
- "Create a contact group for users who signed up this month."
- "Build an automation that sends a welcome series when someone signs up."
See more example prompts.
