Overview

AI-generated overview

Remote MCP server for Post Assembly that lets an assistant capture ideas, draft LinkedIn posts, build narrative arcs and manage a posting schedule.

What you can do
  • Capture ideas and turn them into LinkedIn post drafts.
  • Build and shape narrative arcs across posts.
  • Manage a posting schedule for planned content.
  • Editorial support for LinkedIn writing workflows.
When to use it
Useful when you write for LinkedIn and want an assistant to help move ideas into drafts, structure them into a narrative, and keep a posting schedule in one editorial tool.
Requirements
A remote endpoint at app.postassembly.com using streamable HTTP, with OAuth required. A Post Assembly account and an API key generated at Settings > API Keys, supplied in the x-api-key header.
Before you install
The server requires an API key sent in the x-api-key header, so treat it as a secret. It works on your editorial content and schedule, so expect drafts and scheduling data to be created or changed in your Post Assembly account.

Installation

In SourceWeft

  1. Open Post Assembly in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.postassembly%2Fpost-assembly/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
