How to Use the Document Paginator Engine MCP in Vercel AI SDK

Q: How do I connect the Document Paginator Engine to my Vercel AI SDK project?

Install @ai-sdk/mcp and set up the HTTP client in your route. Call mcpClient.tools() to fetch the chunking tool, then pass it directly to streamText. Always call mcpClient.close() once your streaming session finishes.

Slice legal documents into token-safe chunks and stream the results directly to your React frontend with the Vercel AI SDK.

Token-Safe Slicing with Vercel AI SDK

The `chunk_legal_document` tool splits massive legal files into exact token budgets before sending them to your LLM. It scans the raw text, calculates token weights, and stops cutting right at sentence boundaries so your frontend never receives half-broken clauses. By coupling this MCP Server with your Vercel AI SDK setup, you stream these clean chunks directly to your UI. Users watch the parsed sections populate their screens in real-time instead of staring at a blank loading screen.

Preserve Legal Citations in UI Streams

The `chunk_legal_document` tool uses regex patterns to recognize complex legal abbreviations like F.3d, U.S.C., and v. without breaking them apart. This keeps your citation formats perfectly intact throughout the entire chunking process. When you run this on Edge Functions, the Vercel AI SDK receives clean, context-rich chunks that retain all legal references. Your end users get accurate, readable legal text streamed straight to their browser without any dropped citations.

Avoid Truncation Errors in Edge Runtimes

The `chunk_legal_document` tool calculates mathematical boundaries to prevent raw character-slicing from ruining your legal analysis. It forces the LLM to process complete thoughts, which stops the model from hallucinating missing terms. You can import this tool directly into your edge route and run it alongside `streamText`. This setup guarantees that your Vercel AI SDK application processes massive contracts without hitting context window limits or losing critical legal clauses.

Setup guide

Set up Document Paginator Engine 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 Document Paginator Engine 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 Document Paginator Engine transactions",
});

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

Common questions about Document Paginator Engine MCP in Vercel AI SDK

Install `@ai-sdk/mcp` and set up the HTTP client in your route. Call `mcpClient.tools()` to fetch the chunking tool, then pass it directly to `streamText`. Always call `mcpClient.close()` once your streaming session finishes.

Yes, this MCP Server works perfectly in edge environments because it relies on lightweight mathematical parsing. The tool processes your legal text blocks quickly, allowing the Vercel AI SDK to stream the results without introducing latency.

Basic splitters slice text blindly and often break sentences right in the middle of a legal clause. This MCP Server uses regex-based boundary detection to keep sentences intact, giving your Vercel AI SDK setup reliable data.

Vinkius manages the connection and handles token authentication behind a single endpoint. You only need to pass your Vinkius credentials when initializing the client in your SDK configuration code.

Your legal documents are processed inside an ephemeral, zero-trust V8 sandbox that deletes all text blocks instantly after chunking. No data is written to persistent storage, ensuring your sensitive contract clauses never leave the temporary runtime environment.
