How to Use the LEAP Legal MCP in Vercel AI SDK

Q: How do I stream LEAP Legal matter files using Vercel AI SDK?

You call listleapdocuments inside your streaming text generation function to feed file metadata directly to the frontend. The SDK streams the document list as a React component, letting lawyers browse case files without waiting for a full page reload.

Q: Can I log billable hours with LEAP Legal and Vercel AI SDK?

Yes, you execute createleaptimeentry inside the SDK's tool calling loop. The interface streams the exact recorded minutes and rate back to the attorney's chat window for instant billing verification.

Q: Can I search cases without triggering full page renders?

Yes, you use searchleapmatters inside your streaming function to push matching case results directly to your search bar component as the user types.

Stream live LEAP Legal matters and real-time billing updates directly into your Vercel AI SDK frontend with this MCP Server.

Perplexity

Stream live case creation directly to your UI

The `create_leap_matter` tool acts as the primary driver for opening legal cases instantly from your user-facing Next.js input fields. Your Vercel AI SDK client updates the interface step-by-step as the case is registered, bypassing static loading states entirely. This means when an attorney opens a case, they see the new folder appear in real-time. By integrating this MCP Server, your frontend maps incoming payloads to live UI components without waiting for bulk API response cycles.

Render live billing entries as they happen

The `create_leap_time_entry` tool records billable hours directly from the user's chat window into the firm's ledger. The Vercel AI SDK streams the status of the logged minutes so lawyers get immediate visual confirmation of their billable work. You don't make users wait for a page refresh to see if their time registered. Instead, the MCP connection renders the exact duration and billing rate on the screen the millisecond the database updates.

Display interactive client portfolios in real-time

The `get_client_leap_matters` tool retrieves a client's entire legal history to display inside your React dashboard. Your Vercel AI SDK setup streams this data block-by-block, letting attorneys read early case files while the rest of the portfolio loads. This reduces perceived latency during busy morning lookups. By deploying this MCP Server on Edge Functions, you deliver immediate case data without server-side bottlenecks or stalled UI threads.

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();
