How to Use the Hallucination Detector Prover MCP in Vercel AI SDK

Q: How do I connect the Hallucination Detector Prover to Vercel AI SDK?

Install both ai and @ai-sdk/mcp. Create your client using createMCPClient with the HTTP transport type. Pass the MCP Server URL, fetch the tools via mcpClient.tools(), and feed them to streamText.

Stop streaming plausible fiction to your users. Enforce strict epistemic rigor in your Vercel AI SDK applications.

Stop Hallucinations in Vercel AI SDK

The `validate_hallucination_grounding` tool acts as a strict filter for your LLM outputs. Before your app sends a single token of factual information to the frontend, this tool forces the model to cite verifiable sources. You define the boundaries. The model either provides a DOI, URL, or publication date, or it admits it does not know. Streaming responses directly to a React or Next.js UI creates massive risk if the model invents facts. This MCP Server prevents that embarrassment. It catches uncalibrated confidence and blocks opinion masquerading as objective truth. Your users see real-time data they can actually trust, rather than fast fiction.

Calibrate Confidence Scores

The `validate_hallucination_grounding` tool demands explicit confidence scoring based on evidence quality. A peer-reviewed randomized controlled trial gets a high score. A random blog post gets a low one. The model must quantify its certainty before it speaks. You get to set the threshold for what gets through to your Svelte or Vue application. If the model claims absolute certainty without hard evidence, this MCP Server flags it as epistemic overreach. It forces the system to separate independent facts from subjective assessments.

Detect Internal Contradictions

The `validate_hallucination_grounding` tool cross-references every claim made in a single response. It compares the second paragraph against the sixth. If the model contradicts itself, the tool catches the error before the user ever sees it. Long streaming outputs often drift. The model loses the thread and starts making up numbers that conflict with earlier statements. By calling this tool before rendering the final output, you guarantee internal consistency across the entire generation.

Setup guide

Set up Hallucination Detector Prover 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 Hallucination Detector Prover 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 Hallucination Detector Prover transactions",
});

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

Common questions about Hallucination Detector Prover MCP in Vercel AI SDK

Install both `ai` and `@ai-sdk/mcp`. Create your client using `createMCPClient` with the HTTP transport type. Pass the MCP Server URL, fetch the tools via `mcpClient.tools()`, and feed them to `streamText`.

Yes, verification takes compute cycles. You trade raw speed for factual accuracy. The tool runs its checks before the final text streams to the user, preventing fabricated claims from hitting the UI.

It verifies the claims the model makes against the sources you provide in the context window. If the model cites a specific internal document, the tool checks if that citation actually exists and matches the claim.

The model likely failed to cite a specific source or presented an opinion as a fact. The tool forces the model to state its knowledge boundaries. If the model guesses, the tool rejects the output.

The server processes the specific factual claims and citations generated by your model. It runs entirely inside an isolated V8 sandbox. The execution is ephemeral, meaning your text data vanishes the moment the verification finishes.
