Post Assembly
Run a LinkedIn editorial workflow from your coding agent—ideas, drafts, arcs, and scheduling without leaving Claude Code or Cursor.
Overview
Post Assembly is a MCP server for the Grow phase that lets agents capture LinkedIn ideas, draft posts, build narrative arcs, and manage a publishing schedule via Post Assembly’s API.
What is this MCP server?
- Streamable HTTP remote at app.postassembly.com/api/mcp (Post Assembly server schema 1.0.1)
- Capture post ideas, draft copy, and build narrative arcs inside agent conversations
- Manage an editorial schedule tied to LinkedIn publishing
- Authenticated with required x-api-key from Settings > API Keys after postassembly.com signup
- MCP integration for Claude Code and Cursor—not a standalone writing app
- MCP server version 1.0.1
- 1 streamable-http remote endpoint (app.postassembly.com/api/mcp)
- 1 required secret header: x-api-key
What problem does it solve?
Founders lose thread between scattered notes, half-written posts, and inconsistent LinkedIn cadence because editorial work lives outside the agent where they already plan and ship.
Who is it for?
Solo builders and indie founders who publish on LinkedIn regularly and want agent-native drafting and scheduling with Post Assembly.
Skip if: Teams that need multi-channel social suites, paid ads orchestration, or deep LinkedIn analytics without a Post Assembly account.
What do I get? / Deliverables
After you register the remote MCP server with your API key, your agent can maintain ideas, drafts, arcs, and a schedule in one editorial system instead of ad-hoc copy-paste.
- Agent-callable LinkedIn editorial operations in Post Assembly
- Structured ideas, drafts, arcs, and schedule state in the product
- Repeatable founder posting workflow from the coding agent
Recommended MCP Servers
Journey fit
Canonical shelf is Grow because the primary outcome is sustained LinkedIn publishing and audience nurture after you have something to talk about. Content subphase fits capture-to-publish editorial work rather than one-off launch spikes or generic analytics.
How it compares
LinkedIn editorial MCP integration, not a generic SEO skill or browser automation plugin.
