Enable MCP in RShift, then run:
codex mcp add rshift --url "https://mcp.rshift.com/mcp"
codex mcp login rshiftThe login command opens RShift in your browser. Sign in, choose the workspace, and approve access. Codex stores the workspace-bound OAuth session; no RShift API key or custom header is required.
For multiple workspaces, repeat the commands with a unique server name, use the same MCP URL, and choose a different workspace during OAuth.
Verify the connection with codex mcp list, reopen the session if needed, and test a read-only tool first.
Do not share OAuth authorization codes or access tokens.
