How to Use the Authorize.net MCP in Mastra AI

Q: Can a Mastra AI agent check Authorize.net transaction details before refunding?

Yes, the agent calls gettransactiondetails to verify the original settled amount and card brand. This step ensures your Mastra AI automated workflow never refunds more than the initial Authorize.net purchase value.

Q: How does the Mastra AI workflow handle temporary credit holds on Authorize.net?

The workflow uses authonlytransaction to place a hold during order placement. Once the inventory is confirmed, a subsequent step triggers priorauthcapture to finalize the Authorize.net payment through our MCP Server connection.

Q: Can I edit CIM payment profiles programmatically?

You use the addpaymentprofile tool to append new card records to an existing CIM customer. The Mastra AI agent coordinates this transition, verifying the customer ID matches before sending the payload to Authorize.net.

Build resilient payment workflows that auto-retry failed Authorize.net transactions using Mastra AI agents.

Resilient Charge Captures with Mastra AI Workflows

Processing direct sales is handled by the `auth_capture_transaction` tool within Mastra's stateful workflow engine. If a payment gateway timeout occurs, the engine triggers automatic retries with exponential backoff to prevent abandoned carts. You define these steps in code, mapping failure states to alternative routing. This ensures that transient gateway errors do not break your MCP payment pipeline.

Automated Customer Profile Setup

To register new buyers during onboarding, run the `create_customer_profile` tool to establish the base profile before attaching cards. Mastra AI agents use this tool to manage the sequence without manual script writing. By using the framework's step-based architecture, you can chain this tool with other database writes. The agent confirms the profile exists before proceeding to payment steps.

Guarded Refund Approvals

Reversing settled payments is the job of the `refund_transaction` tool, which targets specific transaction IDs and masked card info. To prevent unauthorized chargebacks, you apply Mastra's human-in-the-loop features to require admin approval. The agent pauses the workflow, alerts a team member via Slack, and only fires the tool once authorized. This mitigates fraud risks while maintaining automated record-keeping.

Setup guide

Set up Authorize.net 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 Authorize.net 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: "authorizenet-mcp-client",
  servers: {
    "authorizenet-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Authorize.net MCP in Mastra AI

Install the library using npm and configure the MCP client. You initialize the client with the Vinkius URL, call `listTools()`, and spread those tools directly into your agent's configuration.

Yes, the agent calls `get_transaction_details` to verify the original settled amount and card brand. This step ensures your Mastra AI automated workflow never refunds more than the initial Authorize.net purchase value.

The workflow uses `auth_only_transaction` to place a hold during order placement. Once the inventory is confirmed, a subsequent step triggers `prior_auth_capture` to finalize the Authorize.net payment through our MCP Server connection.

You use the `add_payment_profile` tool to append new card records to an existing CIM customer. The Mastra AI agent coordinates this transition, verifying the customer ID matches before sending the payload to Authorize.net.

All transmission of cardholder PANs and CIM profiles occurs over encrypted TLS directly to the zero-trust MCP gateway. Your Mastra AI agent never stores decryption keys or unmasked card numbers in local databases.
