Live Financial Modeling in Vercel AI SDK

The `validate_freelancer_budget` tool pipes real-time financial projections into your interface. Instead of waiting for a backend response, your users see their net income update as they adjust their billable hours or expense estimates. This MCP Server handles the heavy math behind the scenes. You simply pass the tool output to your streamText function to keep your React or Next.js components synced with the user's actual business viability.

Automated Revenue Reality Checks

Stop calculating revenue based on a 2,080-hour work year. This tool forces a 65% utilization cap to account for the reality of admin work, marketing, and contract gaps. Your AI client uses this data to show users exactly why they are currently underpriced. It surfaces the 35% non-billable time that most freelancers ignore, preventing them from building a business on a foundation of math errors.

Complete Overhead Accounting

Most freelancers forget to account for self-employment tax, health insurance, and retirement contributions. The tool calculates these hidden costs against the gross revenue to reveal the true net take-home. By integrating this directly into your application, you give users a brutal but necessary look at their financial health. It turns vague income goals into concrete, actionable pricing requirements.

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 Freelancer Budget Prover transactions",
});

console.log(text);

Common questions about Freelancer Budget Prover MCP in Vercel AI SDK

You initialize the client with your endpoint and pass the tool definitions into your agent's configuration. The SDK handles the streaming of tool results, allowing your UI to display the calculated budget metrics instantly.

Yes, the tool calculates your minimum viable rate based on your specific overhead and utilization. It ensures your rate covers all costs including taxes and insurance, rather than just matching market averages.

The tool includes a cash flow buffer calculation that accounts for typical Net-45 or Net-60 payment terms. It identifies potential gaps in your income stream so you can plan for the lag between finishing work and getting paid.

The server runs in an ephemeral Vinkius sandbox. It only processes the specific financial inputs you provide during a session and does not store your tax or income records once the connection terminates.

You risk operating at a loss without realizing it. Many freelancers think they are profitable while actually losing money on every hour worked due to uncounted overhead and excessive non-billable time.
