Generate real license validation code in Cursor

Stop writing mock data when building your license verification logic. Cursor uses the `verify_license` MCP tool to pull real, active license keys from your store and injects them straight into your active editor file. Your coding agent reads live responses to build precise error-handling blocks. It tests your code against actual Gumroad API payloads instead of guessing what the server returns.

Debug your customer checkout flows using this MCP Server

Pull live transaction details directly into your codebase to debug webhook issues. Cursor runs `get_sale` to fetch the exact JSON structure of a customer purchase, letting you inspect payload structures in real time. This eliminates the constant back-and-forth of triggering dummy sales. You can ask Cursor to run `list_sales` to inspect recent transactions and immediately write code that parses those specific customer variables.

Audit subscribers and active buyers while coding

Write your database sync scripts with live customer data right in front of you. The Cursor agent calls `list_subscribers` to fetch actual user accounts so you can verify if your sync logic handles email formats correctly. You can also call `list_payers` to see which customers have bought multiple items. Having this live context in your editor keeps you from breaking production databases when importing legacy user profiles.

Setup guide

Set up Gumroad MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

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".
2

Add the Gumroad MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Gumroad transactions." If the MCP tools are loaded correctly, Cursor will call the Gumroad tools automatically. You can also check Settings → MCP for a green status indicator.
