How to Use the CourtListener MCP in Vercel AI SDK

Q: Can Vercel AI SDK stream CourtListener opinion text?

Yes. When the model calls getopinion, the Vercel AI SDK streams the resulting text chunks straight to your frontend. The user reads the ruling as it downloads.

Q: What happens when CourtListener returns a massive docket list to Vercel AI SDK?

The SDK processes the searchdockets array as it arrives. You render partial lists in your Next.js app before the full payload finishes transferring.

Stream federal court records and legal opinions directly into your React frontends using the Vercel AI SDK.

Stream Dockets with Vercel AI SDK

The `search_dockets` tool lets your Vercel AI SDK app fetch live federal case records and stream them straight into the browser. Your users hate loading spinners. You build a real-time tracking interface for specific cases. Calling `get_court` pulls jurisdiction details, allowing you to render the results in your React components before the fetch even finishes.

Map Out Legal Citations

Using `list_citations` allows your Edge Functions to map out case history on the fly. Tracing precedent usually means clicking through dozens of browser tabs. Hooking this MCP Server up to your frontend lets the agent push interconnected opinions to Svelte instantly. The model reads the raw text via `get_opinion` and extracts the core arguments. Your users watch the summary generate live on their screens instead of waiting for a 10-megabyte batch response.

Audit Judge Disclosures

The `list_financial_disclosures` tool grabs conflict-of-interest data and streams the findings into your dashboard. Investigative apps need fast access to public records. Combining this with `get_judge` builds full profiles for specific bench members. The integration handles the API routing while you focus on the UI components.

Setup guide

Set up CourtListener 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 CourtListener 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 CourtListener transactions",
});

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

Common questions about CourtListener MCP in Vercel AI SDK

Install @ai-sdk/mcp and set up an HTTP transport via createMCPClient. Point the URL to your Vinkius endpoint, extract the tools with mcpClient.tools(), and pass them into streamText.

Yes. When the model calls get_opinion, the Vercel AI SDK streams the resulting text chunks straight to your frontend. The user reads the ruling as it downloads.

It works perfectly. The Vinkius endpoint handles the heavy lifting, so your Edge Function just passes the tool definitions to the model and pipes the output back.

The SDK processes the search_dockets array as it arrives. You render partial lists in your Next.js app before the full payload finishes transferring.

Vinkius runs your queries in ephemeral V8 sandboxes. Your specific searches for case dockets and judge profiles vanish the second the connection drops. We log absolutely nothing.
