Connect Codex to Sunday
One command adds Sunday to Codex. Codex then writes documents and decks to your workspace as pages.
Checked on .
Before you start
You need a Sunday workspace and the connector address for this agent. The address is HTTPS, and it holds a secret token, so treat it as a password. Sunday is in private beta, and a workspace comes with early access.
The steps
codex mcp add sunday --url <address>
Replace <address> with your connector address.
The steps follow the docs of Codex.1
Check the connection
Ask Codex to list your pages. It calls list_pages and tells you how many pages it can see.
A first task
Write the release notes for this branch as a Sunday page, and give me the link.
What Codex can do in Sunday
It can list pages, read a page, edit a page, list comments, and reply to a comment. Each edit makes a new version, and the old version stays. You can limit Codex to one page, and you can set an end time for its access.
Codex runs on the plan that you already pay for. Sunday sells no AI and no credits.
