How to Use the LEAP Legal MCP in Vercel AI SDK

Perplexity

Live matter document streams

Feed case documents straight into your UI using `get_matter_documents_only`. Your users watch the file list populate as the agent fetches data, skipping the dead air of a loading spinner. This keeps your application state in sync with the server. You'll see the exact file names and metadata appear the moment the request hits the LEAP Legal backend.

Dynamic matter detail updates

Populate your forms by calling `get_matter_details`. The AI client parses the response and maps it to your frontend fields in a single pass. Don't waste time manual-mapping JSON objects. The MCP server returns the data structure your app expects, ready for immediate display in your React or Svelte components.

Automated contact management

Sync client information by pushing updates through `update_existing_card` or adding new entries with `create_new_card`. The SDK handles the transport, ensuring your local records match the legal database. It's built for speed. When a user updates a contact, the change reflects instantly without needing a full page refresh or complex state management.

Setup guide

Set up LEAP Legal 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 LEAP Legal 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 LEAP Legal transactions",
});

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