How to Use the FreshBooks MCP in Vercel AI SDK

Q: How do I connect the FreshBooks MCP to the Vercel AI SDK?

Pass the Vinkius endpoint into createMCPClient using the HTTP transport. Then call mcpClient.tools() and hand the array to your generateText function. Always call mcpClient.close() when the stream finishes.

Build React apps that stream live FreshBooks accounting data directly to your users with the Vercel AI SDK.

Stream FreshBooks MCP Server Invoices

This MCP server exposes `list_invoices` and `get_invoice_details` directly to your AI client. You can prompt the Vercel AI SDK to pull open invoices, and the results stream into your Next.js frontend instantly. Users watch the data render component by component instead of staring at a loading spinner. Managing customer records works the same way. When your agent calls `list_clients` or `get_client_details`, it grabs the billing profiles. You pass those profiles into your `streamText` function, letting your application build dynamic billing dashboards on the fly.

Render Live Expense Dashboards

Fetching financial records requires tools like `list_expenses` and `list_expense_categories`. Your agent requests the monthly spend data, and Vercel AI SDK pushes the raw numbers to your UI charts. There is no middleman database to sync. Payment tracking happens via `list_payments`. If a user asks whether a specific client paid their bill, the agent queries the ledger. The response streams back to the browser immediately, confirming cash flow without making the user refresh the page.

Build Time Tracking Frontends

Querying billable hours relies on `list_time_entries` and `list_active_projects` via the MCP. You wire these tools into your Edge Functions. The agent pulls the logs for a specific contractor and formats them into a clean invoice draft right in the browser. Task management integrates through `list_project_tasks`. Developers use this to show users exactly what work remains unbilled. Your Svelte or Vue interface updates as the AI reads the task metadata, keeping the project status highly visible.

Setup guide

Set up FreshBooks 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 FreshBooks 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 FreshBooks transactions",
});

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

Common questions about FreshBooks MCP in Vercel AI SDK

Pass the Vinkius endpoint into `createMCPClient` using the HTTP transport. Then call `mcpClient.tools()` and hand the array to your `generateText` function. Always call `mcpClient.close()` when the stream finishes.

Yes, it pushes the data chunk by chunk. Your React components update as the agent reads the invoices. Users never wait for the entire API response to finish.

Vinkius manages the underlying API tokens. You just provide your single endpoint token via `authProvider`. The agent handles the rest of the OAuth flow silently.

The SDK throws an error that you can catch in your Edge Function. You decide whether to show a fallback UI or prompt the user to try again.

The V8 Isolate Sandbox destroys itself after your session ends. Your client names, billing addresses, and invoice amounts never touch persistent storage. Ephemeral execution means zero residual data.
