Before you connect
What is included in the download?
A plugin manifest, the CPP HTTP MCP connection and campaign, release and queue skills. No token, local server or extra dependencies are bundled.
How does this differ from the general Claude guide?
This plugin packages selected-file campaign planning, batch review and queue checks. The general Claude guide starts from long-form material in a conversation.
Which social networks can I connect?
New connections are currently available for Instagram, TikTok, X, Bluesky, Mastodon, Dribbble. Instagram, TikTok and Dribbble require media; scheduling and publishing support varies by account. Check the account capabilities before choosing a destination.
Does creating a draft publish anything?
A draft stays unpublished until you schedule or publish it. Scheduling authorizes publication at the selected time; it does not add a mandatory approval step. Review first, then schedule. Immediate MCP publishing requires the separate posts:publish permission.
