You can ask Codex to help:

Help me connect MightyAI using the direct MCP server named mighty at https://api.mightyai.app/mcp. Check existing connections first and reuse a matching connection. Ask me before replacing a connection that points somewhere else. Start browser sign-in and help me select my workspace. Do not make advertising changes.

A direct connection does not install Mighty Ads skills. If MightyAI supplied a skills ZIP separately, attach it in Codex and ask it to install those skills as well.
