PostCLI

Publishing skills for AI agents. One CLI, every platform.

Install

npm install -g @postcli/substack

This automatically installs @postcli/cli as a peer dependency. The postcli command becomes available globally.

Usage

postcli <platform><command> [options]

Example with Substack

postcli substack auth login
postcli substack posts list --limit 5
postcli substack notes publish "Hello from the terminal"
postcli substack profile me

MCP Server

Start an MCP server for any installed platform:

postcli --mcp substack

Creating a Plugin

A PostCLI plugin exports two things:

import{Command}from'commander';// Register CLI subcommands under the platform nameexportfunctionregisterCommands(program: Command): void{constplatform=newCommand('myplatform').description('My platform description');platform.command('hello').action(()=>console.log('Hello from my plugin!'));program.addCommand(platform);}// Optional: MCP server for AI agent integrationexportasyncfunctionstartMcpServer(): Promise<void>{// Start your MCP server with stdio transport}

Set your package's main export to point to this file, and @postcli/cli will discover it automatically.
