Perplexity

Stream everbill invoices into your UI

Vercel AI SDK excels at pushing data to the frontend fast. You connect this MCP Server, and your user watches their billing history load instantly. No waiting for a spinner to clear before seeing the results of `list_invoices`. The connection pipes straight into your React or Next.js components. When your client calls `get_invoice`, the line items render on the screen exactly as the agent processes them. You get a reactive interface without writing custom polling logic.

Build interactive client management

Managing contacts usually means building forms and writing validation logic. Skip that entirely. Your users just type out who they want to bill, and the agent hits `create_customer` in the background. You can surface the newly created profile right away. Following up with `get_customer` pulls the exact record down, letting you display the active client status without a page refresh.

Draft bills with live Vercel AI SDK updates

Generating a bill requires knowing what you sell. Your agent executes `list_products` to pull the active catalog, then matches those items to the user's prompt. Once the draft looks good, the system fires off `create_invoice`. The user sees the final amount pop into the UI immediately, confirming the transaction without breaking their flow.

Setup guide

Set up everbill 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 everbill 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 everbill transactions",
});

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

Common questions about everbill MCP in Vercel AI SDK

Install the required packages using npm install ai @ai-sdk/mcp. Then instantiate createMCPClient with your HTTP transport URL. Pass the resulting tools into streamText or generateText.

Yes. When your agent calls `create_invoice`, the resulting data streams directly to your Next.js frontend. Users see the billing details populate immediately.

You pass the auth token through the authProvider config. The MCP Server handles the actual authentication handshake with everbill. Just remember to call close() when the session ends.

Check your agent's permissions. It needs explicit access to run `list_products`. Also verify your transport URL is correct in the client setup.

Financial records like customer addresses and invoice totals stay protected. The V8 Isolate Sandbox ensures that every time you call `get_customer`, the environment remains ephemeral and isolated from other sessions.
