Search the Law with Vercel AI SDK

You use `search_legislation` to find matching acts, statutory instruments, and other legislative documents across the UK. The results stream instantly into your React UI as you type, making the search experience feel immediate. Need something more granular? Call `search_by_subject`. This tool lets users narrow down searches using specific topics within the official database.

Get Specific Legal Sections via MCP Server

If you know exactly what section you're looking for, call `get_section` to retrieve those details. You can also pinpoint a full schedule by invoking `get_schedule`. This precision allows your users to jump straight to the relevant text without browsing. Don't forget about context. Use `get_table_of_contents` first; it gives necessary structure before calling other, more specific tools.

Tracking Legal Updates with Vercel AI SDK

Need to know what changed recently? The `get_recent_legislation` tool pulls the latest published UK laws into your application. Furthermore, if you want a quick overview of all laws from a certain year, just hit up `get_legislation_by_year`. This lets you build dynamic sections showing current legal changes in real time.

Setup guide

Set up UK Legislation 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 UK Legislation 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 UK Legislation transactions",
});

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