Two commands to connect Codex to OPC — no token copy-paste, one-click OAuth consent.

Run codex plugin install opc — pulls our OPC plugin from the Codex Plugin Marketplace and wires up the MCP server.

One-click OAuth

Run codex mcp login opc — your browser opens OPC's secure consent page. Pick scopes, click Approve, done.

Start chatting

Codex now sees your OPC data with audit-logged, scoped access. No tokens to manage, revoke anytime.
