Zernio

Zernio is a software-as-a-service provider offering a unified REST API for social media and messaging automation, which according to its own website bundles posting, scheduling, analytics, and ad campaigns across numerous platforms behind a single access point.

Built on the same API is an official, hosted MCP server that lets AI agents publish posts, manage inboxes, and retrieve metrics across Instagram, LinkedIn, X, TikTok, and other channels without maintaining a separate integration for every platform.
