Claude has strong writing chops but no built-in reach to your accounts. An MCP (Model Context Protocol) server acts as the bridge — Claude asks it to publish, the server talks to each social API, and you keep the credentials on your side.
The three-step setup
- Connect your social accounts to a scheduler that exposes an MCP endpoint.
- Add the MCP server URL and API key inside Claude's connectors settings.
- Ask Claude to draft and schedule — it will call the tools it needs and confirm.
