Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 12 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Checking subscriber status shouldn't require three different tabs and a copy-paste session.
Right now, checking if your SMS list is healthy means opening the main dashboard. You check 'Subscribers' for counts. Then you jump to 'Campaigns' to see recent activity. If you need technical details, you have to go into 'Webhooks' and manually cross-reference IDs—it’s a total click-fest that eats up time.
With this MCP server, your agent handles the whole sequence. You simply ask: 'What are my active subscribers and what webhooks are running?' The AI client runs `list_subscribers` and `list_webhooks`, giving you one clean summary in chat. It's done.
Postscript MCP Server: Manage subscriber, campaign, and keyword data.
The tedious manual steps that disappear are the constant need to navigate between 'Campaign Settings,' 'Keyword Lists,' and 'Subscriber Profiles.' You never have to manually copy an ID or cross-reference a metric across multiple screens again.
You just talk to your agent. It runs `get_campaign` to pull stats, uses `list_keywords` for source data, and tells you the answer immediately. The dashboard is gone; only the conversation remains.
What you can do with this MCP connector
Postscript MCP Server lets your AI client manage every angle of your SMS and MMS marketing campaigns for Shopify stores. You get direct access to subscriber metadata, campaign performance metrics, and keyword management—all through natural conversation with your agent.
Managing Your Contacts
Your agent handles all subscriber data. Use list_subscribers to pull a summary rundown of every SMS contact you have on file. If you need deep info on just one person, run get_subscriber to grab that user's complete profile and metadata. You can also modify an existing profile using update_subscriber if someone changes their details.
Need to get new people signed up? Use create_subscriber to subscribe a fresh user to your SMS marketing list; just remember compliance rules apply there.
Running Campaigns and Checking Results
When it comes to campaign results, you're always in control. You can use list_campaigns to pull a summary of every single campaign you've run or set up over time. If you want the nitty-gritty details on one specific effort, get_campaign pulls detailed performance metrics for that single SMS campaign. For automated sequences—like those abandoned cart flows—you can use list_automations to see a list of all active automation workflows running right now.
Monitoring Your System and Opt-Ins
Your agent keeps tabs on how your system is wired up, too. You'll find that you can check the status of every webhook connection using list_webhooks, or if you need to clean house, you can use delete_webhook to remove an old one, or even create_webhook to set up and activate a brand-new endpoint for data transfer.
For high-level oversight, run get_account_info to pull overall details about your Postscript account and current plan level.
When it comes to how people find you, the agent handles keyword management. Use list_keywords to see every mobile keyword that users use when they opt in to your texts. This keeps a clear picture of what's driving sign-ups.
Putting It All Together
Your AI client acts like a dedicated marketing manager for your Shopify store, handling all the heavy lifting without forcing you to open up any dashboards. You don't need to manually check subscriber status or run reports; your agent just handles it through simple conversation. You can track engagement metrics from campaigns and automate flows while also making sure every single user profile is accurate.

How Postscript MCP Works
- 1 First, subscribe to this server and enter your Postscript Private API Key into the client settings.
- 2 Next, tell your AI agent what you need. For example: 'What was the revenue from last week's flash sale campaign?'
- 3 The agent runs the necessary tool calls (like
get_campaign) and returns a plain text summary of the results right in the chat.
The bottom line is you manage your entire SMS marketing operation using natural language commands, never having to switch apps or navigate complex dashboards again.

Real-World Use Cases
Auditing Campaign Performance
A marketer needs to know which of their three main SMS campaigns generated the most revenue last month. Instead of navigating the campaign dashboard, they ask their agent: 'Show me performance for all campaigns.' The agent runs list_campaigns and then drills down using get_campaign, providing a clear ranking by total attributed revenue.
Troubleshooting Webhooks
The ops team notices that new subscriber data isn't appearing in the CRM. They ask their agent to 'List all active webhooks and check for errors.' The agent runs list_webhooks, identifies a stale webhook, and then uses delete_webhook followed by create_webhook to fix the connection.
Targeting VIP Users
A store owner wants to run a special promotion only for users who have high value. They ask their agent to 'Find all subscribers with premium metadata.' The agent uses list_subscribers and filters the results using get_subscriber, allowing the marketer to send a highly targeted message.
Scaling Keyword Strategy
The marketing lead suspects a keyword is underperforming. They ask their agent, 'Which keywords should I pay more attention to?' The agent runs list_keywords, showing the volume and usage of every opt-in source, helping them reallocate resources.
The Tradeoffs
Dashboard Overload
The user logs into Postscript, clicks on Subscribers, then tabs over to Campaigns, then opens the Webhook settings just to find one piece of data.
→
Don't click anything. Ask your agent directly: 'Give me a summary list of subscribers and tell me if there are any webhook errors.' Your AI client runs list_subscribers, checks list_webhooks, and gives you the consolidated answer.
Ignoring Metadata
A user updates a campaign but forgets to update the subscriber's segment tag, meaning the message won't hit the right people.
→
After running your campaign, immediately use get_subscriber or update_subscriber on key profiles. This ensures the metadata is current before you launch the next message.
Manual API Calls
The dev team has to write a whole script just to check if an account plan changed, wasting hours.
→
Just ask: 'What are my current account details?' The agent runs get_account_info and provides the necessary context without needing custom coding.
When It Fits, When It Doesn't
Use this server if your primary pain point is switching between Postscript's various dashboards. If you spend more time clicking tabs than writing copy, this is for you. This tool excels at reading data: getting details (get_subscriber), listing resources (list_subscribers, list_keywords), and monitoring system health (list_webhooks).
Don't use it if all you need is to manually write a single message; the native Postscript interface handles that. Also, don't rely on it for complex financial reporting; while it gives revenue metrics, you still need specialized accounting tools for GAAP compliance. This is an operational tool for marketing data, not general business intelligence.
