What is the Postscript MCP Server?

Connect your Postscript account to any AI agent and take full control of your SMS marketing orchestration through natural conversation. Postscript is the leading SMS platform for Shopify stores, and this integration allows you to retrieve subscriber metadata, monitor campaign performance, and manage automated keywords directly from your chat interface.

What you can do

  • Subscriber & Audience Orchestration — List all managed SMS subscribers and retrieve detailed profile metadata programmatically to ensure your outreach is always synchronized.
  • Campaign & Flow Intelligence — Access and monitor your SMS campaigns and automated flows (like abandoned cart recovery) directly from the AI interface to track engagement metrics.
  • Keyword & Opt-in Control — List and search through your mobile keywords to maintain a clear overview of your subscription sources via natural language.
  • Operational Monitoring — Track system responses and manage webhook metadata using simple AI commands.
  • Account Visibility — Access high-level account and plan metadata to ensure your SMS operations are always optimized.

How it works

1. Subscribe to this server
2. Enter your Postscript Private API Key from your account settings
3. Start managing your SMS automation from Claude, Cursor, or any MCP-compatible client

No more manual dashboard checking for subscriber status. Your AI acts as a dedicated SMS marketing coordinator or growth manager.

Who is this for?

  • Shopify Store Owners — quickly retrieve subscriber summaries and monitor campaign reach without switching apps.
  • E-commerce Marketers — automate the discovery of top-performing keywords and track automated flows via natural conversation.
  • Operations Teams — streamline the retrieval of SMS metadata and monitor organizational growth health directly within the chat.
