Real-time cost tracking in Vercel AI SDK

Feed your UI live consumption data using `get_user_info`. You stop guessing what a user's session costs and start showing exact dollar amounts as the stream hits the client. Your application logic stays clean by offloading the math to the gateway. It's a direct bridge between your front-end state and your backend billing logs.

Dynamic model routing with LiteLLM

Inject new endpoints on the fly using `create_model` when you need to swap providers without a redeploy. It’s perfect for Vercel AI SDK when you want to shift traffic from a primary model to a cheaper fallback instantly. Check your current paths with `get_model_info` to verify the failover is active. You maintain uptime while the user experiences zero interruption during model migrations.

Manage keys for individual users

Generate unique credentials for every user session with `generate_key`. You restrict scope and limit budget exposure before a single prompt reaches your LLM provider. If a key leaks or a budget hits its ceiling, call `delete_key` to kill access immediately. You keep your infrastructure secure without touching your core application code.

Setup guide

Set up LiteLLM (LLM Proxy & Spend Tracking) 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 LiteLLM (LLM Proxy & Spend Tracking) 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 LiteLLM (LLM Proxy & Spend Tracking) transactions",
});

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