Steps checked against the Codex documentation on September 24, 2026. The Codex CLI, the IDE extension, and the desktop app share the same configuration, so adding Copyfy once makes it available everywhere.

​
Add Copyfy

1

Add the server

Terminal
Codex detects that Copyfy uses OAuth and opens your browser.
2

Sign in

Sign in to Copyfy and click Allow access. To sign in again later, run:
Terminal
3

Try it

Start codex and ask: “Use Copyfy to find 10 winning products in the Pets niche for the US.”

​
config.toml

codex mcp add writes to ~/.codex/config.toml. You can also edit the file directly:
Codex does not expand variables inside config.toml. Keep the key in the environment variable, never in the file.

​
IDE extension and desktop app

Open the gear menu (IDE extension) or Settings (desktop app), go to MCP servers, click Add server, choose Streamable HTTP, and enter https://app.copyfy.io/mcp. Restart the extension if asked, then click Authenticate.

​
Fallback

Copy the URL https://app.copyfy.io/mcp and add it under [mcp_servers.copyfy] in ~/.codex/config.toml as shown above.

​
Disconnect

Run codex mcp remove copyfy. To revoke access from the Copyfy side, click Revoke under Connected apps or revoke the key on the Integrations page. Having trouble? See Troubleshooting.
