Perplexity

Live Client Data Injection

Feed live billing records into your UI without the lag of traditional fetch requests. Use `get_client` to pull specific account details and display them instantly as your agent interacts with the user. Your interface stays responsive while the data streams. This ensures the user sees account statuses the moment the agent retrieves them.

Automated Billing Workflows

Trigger invoice generation directly from your frontend logic using `create_invoice`. You can chain this with `list_invoices` to keep your dashboard updated with the latest totals. This workflow removes the need for manual record syncing between your database and the billing system. The agent handles the transaction loop while your app renders the result.

Dynamic Account Management

Modify client records on the fly using `update_client` to reflect changes in billing addresses or tax information. The MCP server ensures these updates reach the backend immediately. This keeps your customer data accurate without forcing a full page refresh. Your users get immediate confirmation of their profile adjustments.

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 Invoice Ninja (Invoicing & Billing) transactions",
});

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

Common questions about Invoice Ninja (Invoicing & Billing) MCP in Vercel AI SDK

Install the necessary packages and initialize the client using the provided HTTP transport URL. You then pass the tools directly into your `generateText` or `streamText` functions to allow the agent to execute billing operations.

Yes, the agent will receive the error response from the tool execution. You should configure your prompt to handle these failures by asking the agent to notify the user or retry the operation.

Your data remains isolated within the Vinkius sandbox. The connection is encrypted and relies on your unique endpoint token, ensuring no other clients can intercept the billing records.

The server provides immediate access to the latest records. Because the Vercel AI SDK supports streaming, you can show the output of your tool calls to the user as they finish.

The server only touches your client names, contact details, and invoice line items. This data is ephemeral and is never stored or logged by the infrastructure hosting your agent.
