Error strings

codex mcp login

Situation

A remote MCP server in Codex needs OAuth.

Symptom

Tools fail with auth errors or do not appear.

Cause

If no credential source resolves, Codex can connect to the server without authentication. The OAuth login is started separately.

Fix

Run codex mcp login with the server name.

Snippet

codex mcp login SERVER_NAME

Verify

Open /mcp in the Codex terminal UI. The server must no longer be listed as requiring OAuth.
