Automate Bold workflows in Mastra AI

Design complex logic trees that handle failed transactions. Use `list_transactions` to monitor for anomalies and trigger a `refund_payment` if a customer flags a double charge. Your agents can now perform manual tasks automatically. Mastra AI manages the retries and branching logic while this server handles the Bold API calls.

Webhook management for Mastra AI

Keep your systems in sync with your merchant account. Use `create_webhook` to register endpoints that alert your agents whenever a new sale occurs. It keeps your data current without constant polling. If an endpoint becomes obsolete, use `delete_webhook` to clean up your configuration.

Coordinate Bold terminals in Mastra AI

Deploy agents to manage your physical hardware fleet. Use `initiate_terminal_payment` to start a customer charge directly from your workflow engine. The agent verifies the terminal status first. If a device is offline, the workflow can redirect the payment link creation using `create_payment_link` instead.

Setup guide

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

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

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

Common questions about Bold MCP in Mastra AI

You set up a conditional branch in your workflow. If the Bold tool returns an error, your Mastra AI agent can automatically retry or send an alert.

Yes, you can trigger a refund based on specific criteria. Just call `refund_payment` within your agent workflow after validating the transaction ID.

You provide an endpoint token to the server. The connection stays restricted to your specific account, ensuring no other agents can touch your money.

You can manage them programmatically. Use the toolset to list, create, or remove webhooks as your infrastructure requirements change.

Your merchant data stays strictly between you and Bold. The MCP Server acts only as a bridge, and all logs are ephemeral to prevent data leakage.
