Add the server in Codex CLI, start OAuth sign-in, and return to Codex after approving access in the browser. Check the connection with codex mcp list. Add this URL in your client’s remote MCP settings, then approve access in the browser. WorkBuddy has been tested; other clients need remote MCP and OAuth support.

Ask your AI assistant to check your 550W AI credit balance, then show your recent media processing tasks. Processing tasks use your account credits at the current website prices.
If the email link opens in another browser, return to the original authorization tab. If the request expires, reconnect from your MCP client.
