Perplexity

Inject live SMS data into your Cursor workspace

Stop writing code against stale mock data or guessing API payloads. When you write custom checkout flows or sign-up forms, this MCP Server lets you pull actual customer records into your editor. Your Cursor agent can run `get_subscriber` to fetch live profiles so you can see exactly how your code handles real-world data. If you need to test how your app processes list updates, you can trigger actions right from your terminal chat. Have the editor execute `update_subscriber` or `create_subscriber` to verify your database syncs without leaving your active file.

Debug webhooks instantly with this Cursor MCP Server

Writing webhook handlers is painful when you have to trigger events manually in a browser UI. This Cursor MCP Server lets you control your webhook registrations directly from your development environment. You can call `create_webhook` to point events at your local tunnel and start testing immediately. If you need to see what routes are currently active or tear down old test endpoints, just ask your agent to run `list_webhooks` or `delete_webhook`. It cuts out the middleman so you can focus on writing clean integration code.

Audit automated SMS campaigns as you write code

When you are building custom dashboards or reporting tools for Shopify merchants, you need to know what marketing assets are active. Instead of digging through API documentation, use `list_campaigns` and `list_automations` to see the exact structure of your live SMS flows. You can also call `list_keywords` to fetch your active opt-in keywords and verify that your custom landing pages are referencing the correct sign-up triggers. This keeps your front-end code perfectly aligned with your actual SMS marketing setup.

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
