Stream payment data directly into your UI

Your AI client can trigger `create_one_time_payment_link` or `create_recurring_payment_link` and stream the result directly to your frontend. No more waiting for spinners or batch updates. Your users see the checkout link appear the moment the agent finishes the task. It makes your interface feel immediate and responsive.

Manage subscriptions using Payfunnels MCP Server

Call `list_subscriptions` or `get_subscription_details` to pull customer data into your application state. You can show users exactly what they are paying for without manual database syncing. It keeps your application logic clean and focused on the user experience. You just pipe the output from the MCP server into your components.

Handle refunds and fees with zero friction

Run `refund_payment` or check `list_setup_fees` through your agent to resolve customer issues in real-time. You don't need to build custom admin dashboards for basic financial tasks. Your code stays lean because the agent handles the API communication for you. It's a quick way to add professional financial controls to your product.

Setup guide

Set up Payfunnels MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all Payfunnels tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Payfunnels transactions",
});

console.log(text);
await mcpClient.close();
