MCP
Connect AI assistants to the Zernio API using the Model Context Protocol
Connect AI assistants to the full Zernio API using the Model Context Protocol (MCP). Schedule posts, manage ads, automate DMs, run sequences, and more across 14 platforms, all through natural language.
The Zernio MCP server exposes 480+ tools covering every API endpoint (20 hand-crafted core tools plus one auto-generated tool per endpoint). It works with Claude, Claude Code, ChatGPT, Cursor, Windsurf, and any MCP-compatible client.
Use Zernio in your AI client
Zernio runs as a single hosted MCP server at https://mcp.zernio.com/mcp. Pick your client:
Claude (web, desktop, mobile) — Settings → Connectors → Add custom connector, then enter https://mcp.zernio.com/mcp. You sign in with your Zernio account (OAuth); no API key needed. Full steps in Setup.
Claude Code — install the plugin:
/plugin marketplace add zernio-dev/zernio-claude-plugin
/plugin install zernio@zernioIt prompts once for your Zernio API key (stored in your system keychain).
ChatGPT — add a connector pointing at https://mcp.zernio.com/mcp and authorize with your Zernio account (OAuth).
Any MCP client / the MCP Registry — Zernio is published to the official MCP Registry as com.zernio/zernio. Most MCP clients can add the remote server directly:
https://mcp.zernio.com/mcpAuthenticate with OAuth (sign in with Zernio) or an Authorization: Bearer <your API key> header.
