How to Use the BILL (Bill.com) MCP in Vercel AI SDK

Q: How do I handle streaming BILL (Bill.com) data in Vercel AI SDK?

You initialize the client with your Vinkius endpoint using createMCPClient. Pass the tools array from the client directly to streamText, which lets the agent fetch bills or invoices and stream the results to your frontend components.

Q: Can I use Vercel AI SDK to filter BILL (Bill.com) vendors?

Yes. The agent uses the listvendors tool to pull your payee list. It then filters the raw data on the fly, streaming only the relevant vendor records to your UI.

Q: How do I close the BILL (Bill.com) connection in Vercel AI SDK?

Always call mcpClient.close() once your stream completes or the Edge Function finishes execution. This prevents hanging connections and keeps your serverless execution times low.

Stream BILL (Bill.com) financial data directly into your Vercel AI SDK frontend without annoying loading spinners.

Stream live invoice feeds in Vercel AI SDK

Let your users view outstanding invoices as they load. Instead of staring at a blank screen, this setup pulls from `list_invoices` and streams the data directly into your React components in real-time. If a user asks about a specific unpaid balance, the client calls `get_invoice` and renders the exact dollar amount instantly. No waiting for the whole payload to resolve before the UI updates.

Instant vendor lookups via Edge Functions

Keep your financial dashboard fast by running this MCP Server on Vercel's edge network. Your agent can call `get_vendor` or `list_vendors` to verify payees right inside the chat window. Because it runs close to your users, checking vendor profiles takes milliseconds. The agent pulls the exact profile via `list_accounts` to map the vendor to the correct ledger code without lag.

Zero-latency bill detail rendering

Stop making users click through heavy enterprise portals just to view an accounts payable record. Your AI client grabs the details with `get_bill` and passes it to your custom Next.js UI components immediately. By using this MCP client to feed the output of `list_bills` directly into the SDK's stream, you let users scan their entire queue of pending payments without a single page refresh.

Setup guide

Set up BILL (Bill.com) 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 BILL (Bill.com) 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 BILL (Bill.com) transactions",
});

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