How to Use the Context7 MCP in Vercel AI SDK

Q: Can I use Context7 with streamText in Vercel AI SDK?

Yes. You pass the tools from mcpClient.tools() directly to streamText, allowing the model to resolve the library and stream the documentation live.

Q: Do I need to manually close the MCP Server connection in Next.js?

Yes, you should call mcpClient.close() inside your API route or Server Action. This ensures your serverless functions spin down cleanly without dangling connections.

Q: What data does Context7 collect from my documentation queries?

Only the library names and search terms you pass to resolvelibrary. Vinkius processes these queries in ephemeral sandboxes, meaning your search history and proprietary library IDs are never saved to disk.

Feed live library docs and code examples straight into your Vercel AI SDK streaming UI without waiting for static builds.

Feed Vercel AI SDK real-time docs

Stop training your models on stale APIs. When your users ask for the latest React or Svelte syntax, your Vercel AI SDK application uses `resolve_library` to map the framework to its exact version path on the fly. The model then pulls fresh, context-rich code snippets using `query_docs` and streams them straight to the frontend. Your users watch the exact, current code render line-by-line instead of staring at a blank loading spinner.

Edge-ready MCP Server documentation lookups

Heavy SDKs choke on the edge, but this lightweight MCP Server integration keeps your Next.js Edge Functions fast. By initializing the connection with `createMCPClient`, you fetch precise framework specs without bloating your serverless bundle. Your agent calls `mcpClient.tools()` to grab only the necessary documentation blocks. Once the streaming response finishes, `mcpClient.close()` cleans up the connection immediately to prevent memory leaks in ephemeral environments.

Zero-friction token handoffs for private docs

If your team relies on private library paths, you cannot expose raw credentials to the client. This setup uses the SDK's native `authProvider` to pass secure tokens directly to the `context7-mcp` endpoint. The AI client queries `resolve_library` using the user's authenticated session, keeping your proprietary code structures private. Your developers get instant, secure code generation without hardcoded keys in their frontend code.

Setup guide

Set up Context7 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 Context7 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 Context7 transactions",
});

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