FAQ — NotFair X Ads for Codex
Everything you need to know about installing and using the NotFair X MCP inside OpenAI's Codex CLI.
It's an MCP (Model Context Protocol) integration for OpenAI's Codex CLI. Once added, Codex can read your X (Twitter) ad accounts in real time, then diagnose issues, recommend fixes, and propose changes you approve in chat.
Same backend, different client. The Codex CLI calls the NotFair X MCP server using OpenAI's MCP support. The Claude Connector and Claude Code plugin call it from Anthropic's clients. Capabilities are identical.
Under a minute. Run a single `codex mcp add NotFair-XAds --url https://notfair.co/api/mcp/x_ads` command in your terminal — Codex walks you through the OAuth flow and registers the MCP automatically.
