Post Assembly
Post Assembly is a MCP server that lets agents capture LinkedIn ideas, draft posts, build narrative arcs, and manage a publishing schedule via Post Assembly’s API.
About
Post Assembly is a hosted MCP server that wires LinkedIn-focused editorial tooling into AI coding agents. developers and founders who treat LinkedIn as a distribution channel can register the remote endpoint, supply an API key, and use tools to capture ideas, draft posts, connect posts into narrative arcs, and manage a publishing schedule—without switching to a separate content CMS. It fits the Skillselion journey when you are in Grow (content and lifecycle) but also supports Launch distribution planning and early Idea audience research. The server is version 1.0.1 with an open app repo on GitHub and a commercial product at postassembly.com. Complexity is beginner-friendly: sign up, generate a key, add the MCP remote with the secret header. It does not replace LinkedIn analytics suites or SEO tools; it optimizes the writing-and-scheduling loop for founders who already post or want a structured habit from their agent.
