Use Migma MCP in ChatGPT when your workspace supports custom MCP connectors or ChatGPT developer mode. Use it for campaign review, email preparation, exports, contact checks, and safe test sends.
When ChatGPT asks for authentication, use a Migma API key from Settings -> Developers -> API Keys.
ChatGPT MCP support depends on workspace plan and admin settings. If custom MCP connectors are not available, use Cursor, Claude, Codex CLI, or the Migma API instead.
