The PostNitro MCP server lets AI assistants and agents — Claude (Desktop, Code, and Cowork), Cursor, ChatGPT, and any other Model Context Protocol client — create carousels and image posts, manage brand kits and connected social accounts, and schedule posts directly.
Instead of writing REST API calls, you connect the server once and your AI assistant gets ready-made tools covering carousel and image generation, brands, social accounts, and scheduling — using the same Embed API key and credits as the REST API.
