How to Use the Deterministic Math Expression Evaluator MCP in Vercel AI SDK

Q: How does the Deterministic Math Expression Evaluator work with the Vercel AI SDK?

It connects as a tool provider. You use the AI SDK's createMCPClient to link to this MCP server, then pass the evaluatemath tool to streamText. Your AI agent can then call the tool to solve math problems, with results streaming into your UI.

Get correct math results streamed into your UI with the Vercel AI SDK. No spinners, just answers.

Real-time Calculations in Your UI

The `evaluate_math` tool gives your AI client a calculator that shows its work. As your agent solves a problem, the results can stream directly into your React components. Users see numbers update live, not after a delay. This is built for the Vercel AI SDK. It hooks right into `streamText`, turning what used to be a backend-only task into a live part of your user experience. It just works.

Secure Math, No `eval()`

The `evaluate_math` tool uses a strict Abstract Syntax Tree (AST) parser. That means it only understands math, nothing else. It's impossible to trick it into running arbitrary code. This Vinkius-managed MCP server runs the calculation in an isolated sandbox, keeping your application and your users safe. You can let your agent handle user-provided formulas without worrying about code injection. It’s the right way to do math with an AI.

Drop-in Vercel AI SDK Integration

Your agent gets the `evaluate_math` tool with a straightforward setup. Just install the MCP client, point it to the server URL, and pass the tools to `generateText`. Your agent is now ready to do math. The Vinkius platform handles all the authentication and scaling. You get one endpoint token and you're done. No server maintenance, no extra config.

Setup guide

Set up Deterministic Math Expression Evaluator 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 Deterministic Math Expression Evaluator 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 Deterministic Math Expression Evaluator transactions",
});

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

Common questions about Deterministic Math Expression Evaluator MCP in Vercel AI SDK

It connects as a tool provider. You use the AI SDK's `createMCPClient` to link to this MCP server, then pass the `evaluate_math` tool to `streamText`. Your AI agent can then call the tool to solve math problems, with results streaming into your UI.

Yes, it's designed for it. The tool uses a parser that only accepts mathematical expressions, preventing any code injection risks associated with `eval()`. All operations are sandboxed and secure.

Predictability. Your AI agent gets a dedicated, error-proof tool for algebra, so it won't hallucinate or make simple arithmetic mistakes. This guarantees correct calculations every time.

It handles standard algebraic expressions. This includes numbers, arithmetic operators (+, -, *, /), parentheses for order of operations, and common functions. It's made for business and scientific math, not for solving abstract calculus.

The server only processes the string-based mathematical expressions you send to the `evaluate_math` tool, like `"(5 + 3) * 2"`. Each request is handled in an ephemeral, zero-trust environment, and the expression data is not logged or stored.
