Pro tip

Auto-invoke Postking MCP for LinkedIn

Add a rule so your assistant automatically calls Postking tools when you ask about drafts, scheduling, or client content. This keeps workflows consistent without extra prompting.

Always use the Postking MCP tools when I ask about LinkedIn drafts, scheduling, publishing, or client content workflows.
