Connect Codex
Add quickS3 to OpenAI Codex as a remote MCP server, sign in from the terminal, and pick the roles it gets. One setup covers app, CLI, and IDE.
-
Add the server:
codex mcp add quicks3 --url https://quicks3.com/mcp -
Sign in:
codex mcp login quicks3Your browser opens quickS3.
-
Untick the roles Codex doesn’t need, pick how long the access lasts, and select Authorize. Approve an AI client explains each part.
-
In Codex, try: “List my quickS3 connections.”
The Codex app, CLI, and IDE extension share the same MCP settings, so one setup covers all of them.
Check what it can reach
Ask Codex to list a folder its role should allow, then one it shouldn’t. The second should fail. If it doesn’t, the roles you approved give more than you meant to: revoke the access and approve it again with fewer roles.
Disconnect
Select Revoke next to Codex on the AI agents page in quickS3. That stops it straight away. To also remove the server from Codex, run:
codex mcp remove quicks3
