How to Use the Gumroad MCP in Mastra AI

Q: Can Mastra AI conditionally generate Gumroad discount codes?

Yes, you can write a workflow that queries listproductsubscribers and conditionally calls createoffercode. Mastra handles the branching logic so discounts only go to verified accounts.

Build resilient TypeScript workflows that auto-retry Gumroad sales audits and conditional discount creation using Mastra AI and MCP.

Build automated Gumroad sales workflows with Mastra AI

The Gumroad MCP Server exposes `list_sales` to let your Mastra AI workflows pull raw transaction logs on a set schedule. If a network blip occurs, the framework's built-in retry logic executes exponential backoff to ensure no transaction log is missed. Once the logs are fetched, the workflow uses `get_sale_details` to inspect individual customer charges. This allows you to build multi-step flows that trigger internal alerts only when high-value purchases fail.

Conditional discount logic for active subscribers

This MCP Server provides `list_product_subscribers` to feed your agentic workflows with clean customer lists. You can configure a Mastra AI step that checks if a customer is an active subscriber before running any promotional actions. If the check passes, the workflow triggers `create_offer_code` to generate a personalized discount. The framework handles the conditional branching natively, ensuring discounts are never sent to non-subscribers.

Human-in-the-loop product inventory checks

By exposing `list_products` and `get_product_details` through this MCP Server, your agent can monitor your digital inventory and flag discrepancies. You can require manual admin approval inside Mastra AI before the agent updates any product visibility. The workflow halts when the agent runs `get_user_profile` to verify store ownership details. Once you approve the step in your console, the agent resumes its automated maintenance routine.

Setup guide

Set up Gumroad MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Gumroad tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "gumroad-alternative-mcp-client",
  servers: {
    "gumroad-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Gumroad Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Gumroad tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Gumroad transactions"
);
console.log(result.text);

Common questions about Gumroad MCP in Mastra AI

You configure Mastra's built-in retry engine on the agent tools. If a call to `list_sales` times out, the framework automatically retries the request using exponential backoff before throwing an error.

Yes, you can write a workflow that queries `list_product_subscribers` and conditionally calls `create_offer_code`. Mastra handles the branching logic so discounts only go to verified accounts.

You instantiate the client with the Vinkius endpoint and call the tool listing method. Then, you spread those tools directly into your agent's tool configuration array.

Yes, you can set approval flags on the tool definition. This forces the system to pause when the agent attempts to run `create_offer_code` until you manually click approve.

Customer email addresses and subscription records fetched via `list_product_subscribers` are processed entirely in memory. Vinkius encrypts all credentials in transit and executes the code inside isolated, zero-trust runtimes.
